Third Day of Special Training "The Haunted House – Ghost Mansion and the Promise of That Day"


Scene 5: Third Day of Special Training “The Haunted House – Ghost Mansion and the Promise of That Day”

Since Chika started staying at our house, the first weekend had arrived.

I was in my room, facing the computer screen, playing a game… or rather, I wasn’t.

Instead, I stood there, squinting at the bright sunlight pouring in, arms crossed, listening attentively to the hustle and bustle around me.

Passersby included groups of girls around my age and families out for a stroll. It was rare to see men alone; it was mostly lively groups.

And rightly so.

After all, I was at…

“Welcome to Ashihara Fantasy Land!”

“Ah, Takkun! Sorry, I took a bit longer than expected!” Chika appeared, waving her hand and coinciding with the park’s announcement.

Wearing a navy blue dress, different from her uniform or casual clothes, she waved at me and I nodded in response.

“No worries. I enjoy people-watching, so I was just taking it all in.”

“A lonely hobby, I must say… But thanks, I managed to buy this!”

She pulled out a cat-ear headband from her shopping bag. It was a replica of “Nekomatan,” the mascot cat character of the amusement park.

Many girls around us wore similar accessories. It seems girls are drawn to such things… or maybe it’s like how boys can’t resist buying wooden swords on school trips.

“Does it look good on me?” Chika asked, gleefully trying it on.

“Looks great,” I replied casually.

Chika, sometimes reserved, sometimes wildly carefree, reminded me of a cat. The black cat ears contrasted strikingly with her platinum blonde hair… but saying that out loud felt too embarrassing.

“Wow, that girl is so cute…” A man walking by with his girlfriend said in admiration, only to receive a glare from her. I couldn’t help but agree. Adorable. Incredibly adorable. I wished I could capture the moment in a photo.

Ignoring my thoughts, Chika pouted at my brief reply, but quickly cheered up and said, “Alright, shopping’s done. Let’s continue our special training today!”

Indeed, we were here for her “special training” under the guise of visiting the local amusement park.

The reason for choosing an amusement park was simple – my parents had returned from an exorcism job and gave us tickets they received as a thank you. Though too old for amusement parks, they passed them on to us.

I wasn’t particularly interested in amusement parks, and thought of giving them to Kasumino. However, Chika suggested, “Let’s do our special training at the haunted house in the amusement park.”

If that’s what she wanted, I couldn’t refuse. Hence, we found ourselves here this weekend.

This was certainly not a date or anything fun like that…

Back to the story.

After browsing the souvenir shops, we were ready for today’s special training. Chika was leading the training, so I followed her to the chosen attraction…

“…We’re going on this?”

We arrived at a terrifyingly tall free-fall ride – a classic scream-inducing attraction.

It must’ve been forty or fifty meters high. Just looking up made my neck ache. Slowly ascending seats reached the top, then plummeted down, echoing screams of the riders.

Chika pointed excitedly at the ride, “This is one of the park’s most famous attractions. It’s known for its height and speed. I always wanted to visit… no, I thought it’d be good for my training.”

“I see. So far, your training has been all about overcoming fear, so this makes sense… But still,” I hesitated, knowing my own fears.

“I think we should skip it. It looks dangerous.”

To be honest, I’m terribly afraid of thrill rides. Horror doesn’t faze me, but the physical shock of rides, especially high ones, is too much. I had vowed never to ride one again after a traumatizing experience in a school trip.

“Accidents could happen, you know.”

Chika confidently reassured, “It’s been operating safely for five years.”

“Being prepared for accidents is always important,” I argued.

“Don’t worry. They do daily checks on ‘The Screaming Spin of Death,'” she said.

“That name is far too ominous!”

Despite my protests, Chika looked at me intently and said, “…If Takkun really doesn’t want to, we can skip it.”

Faced with that, I couldn’t refuse. She was eager for her training, and I couldn’t be the one to stop her.

So, there I was, nervously fastened tightly in the seat.

After waiting in line for a while, we were finally seated. Height checks and medical history inquiries were part of the process – they were serious about safety.

Despite my fears, I couldn’t back out now. Chika was working hard to overcome her fears, so I had to face mine.

As the safety bar locked and the staff completed their checks, my seat began ascending.

“Wow, oh wow,” Chika exclaimed, her voice filled with excitement, unlike her usual scared tone.

“Look, the ground is getting farther away. Amazing!”

“Yeah, amazing…” I agreed, trying to hide my fear.

As I watched the crowd on the ground shrink rapidly below us, I felt an intense homesickness for Mother Earth. Yet, undeterred by my thoughts, the ride continued its ascent into the sky.

Slowly, slowly, it climbed. I wished it would just reach the peak quickly, but perhaps this prolonged fear was part of the calculated experience. I was already feeling nauseous.

Meanwhile, Chika, as expected, looked thrilled and said, “We’re about thirty meters high now, still going up, it’s amazing!”

“Yes… amazing…”

Finally, at the peak altitude, the seat stopped. From this height, we could see the far reaches of the park and the clear blue sky, with crowds moving below – a sense of omnipotence from being able to view both worlds. This realization made me pause for a moment.

But, my overwhelming desire for this to end surpassed any other feeling.

Next to me, Chika was sparkling with excitement, surveying the surroundings.

After a few seconds or perhaps a minute, the moment came abruptly. The seat plummeted down at a terrifying speed.

From defying gravity to being pulled back to earth, the intense air pressure made me involuntarily scream.

“Ah, waaaahhh!!??”


The former was my scream, and the latter, Chika’s. Though screaming, it was clear she was having fun.

Once we reached the ground and the safety bar was released, Chika, her cheeks flushed, turned to me and said, “Hey, hey Takkun! That was so fast, I was shocked! …Takkun?”

I just stared, speechless and stiff, which made Chika look at me curiously.

Well, I thought, at least I managed to stay conscious. I should be proud of myself for that.

And I resolved to be a bit kinder to Chika during these training sessions.


After experiencing the park’s most thrilling ride.

Chika, undeterred, suggested we go on the roller coaster next.

I realized she must really love thrill rides. While it felt wrong to stop her – and honestly, I didn’t want to dampen her spirits – I silently followed her lead.

By the time we had finished three rides (this amusement park had an absurd number of thrill rides), I was completely drained.

“Ah, that was scary. They were all so intense!”


I replied, completely exhausted, in contrast to Chika’s lively demeanor.

“…But I didn’t expect this. You like these kinds of attractions, Chika?”

It was genuinely surprising. She usually screams so frightfully, yet she seemed so alive on thrill rides.

At my comment, Chika responded uncertainly, “Well, this was my first time actually riding them, so I didn’t know if I’d like them. But it was fun, so I’d like to ride them again if we come back.”

I thought to myself, she should definitely ride them alone next time. Though, if we come back, it might not necessarily be with me.

As I was pondering this, Chika pointed to a nearby bench, suggesting we take a break.

After sitting a short distance apart, she complained about the gap, so I moved closer.

We sat in silence for a while until Chika suddenly spoke.

“When I’m here, I remember when I came as a child.”


Surprised by her unexpected comment, she continued with a wry smile, “Don’t you remember? When I was five, we came here with your parents.”

“Ah… yes.”

I remember that time well.

Observing me, she hesitantly asked, “So, do you… remember what happened at the haunted house back then?”

“Hmm, yeah. Chika got so scared that she wet herself and fainted, and we had to carry her out with the staff dressed as ghosts…”

“You didn’t have to explain it in such detail…”

Chika blushed, slightly annoyed. Oops, I lacked delicacy.


“No, it’s okay. I brought it up… I’m glad you remember that time with me.”

“I remember it well. We always had fun together, Chika.”

Hearing my sincere response, she looked surprised, then shyly smiled and whispered, “Ehehe, I see.”

She gazed at me and continued, “Then, do you remember… that thing?”

“That thing? What do you mean?”

“Um, you know, that…”

She hesitated, then sighed and shook her head. “Never mind, it’s okay.”

“What is it? Now I’m curious.”

“It’s okay for now,” she insisted, standing up abruptly. “Anyway, let’s decide on the next attraction… I mean, training. Which do you prefer, ‘Super Swinging Pirate Ship’ or ‘Shocking Dragon Rider’?”

“Why does this amusement park have so many scream-inducing rides…”

I remember it wasn’t like this when I visited in the past. With that thought, I pondered my next move.

If we continue with more thrill rides, I might not survive. Besides, this isn’t really helping her training.

After some thought, I pointed to a spot in the pamphlet.

“I think we should go here.”

“…You mean, the haunted house we visited before?”

Exactly as she said. The attraction, named “Curse and Murder House,” was a haunted house – the very place where she had previously faced a grand defeat.

“With the training so far, I think you’ve built up a resistance. It might be good to confront this past trauma head-on.”

Hearing this, Chika made an obviously displeased face, but surprisingly, she soon nodded in agreement.

“True, I’ve become stronger. Considering the training so far, that haunted house feels like child’s play now.”

“Great spirit!”

Confidence and motivation are key. With my encouragement, Chika nodded confidently and declared,

“Hehe, then let’s go show the new me, reborn through training with you, Takkun!”

“Looking forward to it.”

Though in my mind, this felt like a classic setup for disaster.

But, it’s best not to voice such thoughts.


And so, we headed to our destination, the “Curse and Murder House.”

Within the fancifully themed Ashihara Fantasy Land, this attraction stood out, blatantly ignoring the surrounding atmosphere – a classic Japanese-style haunted house.

It was originally created as a tie-up with a famous horror movie and remained as a permanent attraction due to its popularity. Over time, it collaborated with various horror movies and games, sometimes completely changing its content, attracting many repeat visitors.

But let’s leave the explanation at that.

It was as popular as ever, showing a one-hour wait when we arrived. Chika began to show signs of backing out, but I decided to ignore it, and we lined up.

Looking around, there were more couples compared to other attractions. Noting this, I glanced at Chika.

I shouldn’t think about it too much, but it was hard not to be conscious of it.

To distract myself from these troubling thoughts, I simply watched the people passing by.

After about an hour, as the sign indicated, it was finally our turn. We were led inside by a staff member to a room styled like a traditional Japanese entrance, where a walkie-talkie was placed on a stand.

The staff member had left, and instructions came through a TV monitor. It advised using the walkie-talkie in case of any trouble or desire to leave midway.

Who should carry it? Glancing at Chika,

“…Takkun, you carry it. I might use it too soon otherwise.”

After a moment of thought, she said that, so I strapped the portable belt around my waist and placed the walkie-talkie inside.

With preparations complete, the video announcement continued. We were to play the role of investigators in a cursed house. Our task was to search the house thoroughly and find the source of the curse. The main character of the movie tied to the attraction explained this, then the monitor displayed a message.

“How many are entering?”

“…Just the two of us, obviously.”

I casually touched the monitor to select our response, then answered “No” to the next question, “Are you a family?”

The man in the video smirked mysteriously and said, “I see, just the two of you… perhaps you might…”

His cryptic words were followed by static on the monitor, briefly showing the face of a horrifying woman.

“Ah! N-no, I’m totally fine with this!”

Chika, clearly startled, jumped but quickly composed herself, unasked.

So I responded earnestly.

“Right. If we get scared by this, we won’t be able to explore inside. Let’s do our best.”


Agreeing, the door ahead opened, and we officially stepped into the “house.”

Inside, it appeared to be a spacious traditional Japanese house, typical of an attraction. However, it lacked any windows, making it perpetually dim. Walking on the creaky wooden floor, relying only on footlights, we were startled by a strange, metallic scraping sound, causing Chika to widen her eyes in shock.

She barely managed to suppress a scream. Once the noise stopped, she exhaled with relief and looked at me expectantly.

“You’re doing great, Chika. You would have definitely been out with that sound before.”

“Hehe, praise me mo─”

Her words were cut short by a sudden, thunderous noise and flickering lights. Seeing a shadowy figure on the nearby sliding door, she stopped speaking.

She managed not to scream but was visibly trembling all over.

After staring at the door for a few seconds, Chika timidly suggested, “Hey, Takkun, I have an idea.”

“What is it?”

“Let’s hold hands.”


“Well, you know, it’s dark in here. Wouldn’t want to get lost, right?”

Her rapid speech betrayed her anxiety, but I nodded in agreement nonetheless.

“Alright, here─ whoa!”

Expecting a light touch, I was surprised when she firmly grasped my hand.

Her hand was slightly smaller and slender. This was the first time we held hands since she started living with us.

“What’s up, Takkun? Are you scared too?”

She asked, tilting her head at my startled reaction. It wasn’t the case, but maybe it was better to let her think so.

“Yeah, this haunted house is quite something. The production is totally different from before.”

That was a genuine reaction. Maintaining my composure, I replied, and she nodded vigorously in agreement.

“Don’t worry, I’m not scared at all anymore after all the training you’ve given me.”

“Let’s not use that phrasing, please.”

It seemed she regained some confidence thinking I was scared too, holding my hand tightly and stepping forward boldly.

“…Takkun, you go first.”


I figured it wouldn’t be right to push Chika too hard. Sighing, I decided to lead the way.

We cautiously moved through the dim corridor. Unlike the past, where costumed staff would frequently jump out, the approach now seemed different, focusing more on a Japanese horror style with darkness and occasional strange noises.

But Chika’s hand, still holding mine, was sweaty and intermittently tightened its grip. Honestly, I was more concerned about her than feeling scared myself.

I just wanted it to be over, and then, we entered a large room that appeared to be a Buddhist altar room. There was a sliding door at the far end, a few meters away.

It felt like a setup for a trick. I glanced at Chika, and she returned my gaze.

“What’s wrong, Takkun? Are you scared here?”

“You seem more scared than I am.”

“No, no, I’m fine. Totally fine. Surprisingly, no ghosts have appeared yet!”

I decided not to point out her trembling voice. As I gave her a skeptical look, she squeezed my hand harder and hurriedly added,

“Look, I’ll prove I’m not scared! I’ll go to that door over there.”

“Are you sure?”

“Yes. It’s just dark and has strange noises, but that seems to be it!”

As if to defy her own ‘death flag’, she let go of my hand and confidently took a step forward.

Then, the door behind us slammed shut with a loud “clank.”


“It’s locked,” I noted almost simultaneously. Suddenly, the metallic sound filled the room, growing louder.


Unable to hold back any longer, Chika screamed. But that wasn’t all. The walls started moving, and a huge, ominous woman’s face was projected onto the ceiling.

Even I was taken aback by this, partly due to the technical advancement.

And of course, Chika was terrified.

“Meahhh! The face! On the ceiling!”

As she screamed, a man’s voice from the speakers, the same one from the initial guidance, echoed.

“Trouble! The evil spirit inhabiting this mansion is awakening! I’ll tell you two the method to exorcise it, listen closely, I’ll only say it once!”

We waited with bated breath for his words.

“Spirits are weak to strong life force… love! Show the spirit haunting this mansion your love – a passionate kiss!”


I exclaimed, realizing the announcement’s implication. Was this a special setup because we were not a family and came as a pair? What if two male friends entered?

Ignoring these thoughts, I turned to Chika, half-expecting her reaction.


She seemed determined. Placing her hands on my cheeks, she prepared to kiss me.

“Wait, wait, wait. Let’s not go that far.”

“Exorcism requires it. Don’t worry, I’m wearing lip balm today.”

“That’s not the point!”

Though my voice was calm, I was in complete disarray.

She leaned closer, our faces almost touching. My cheeks burned, either from my own tension or the warmth of her hands. Chika’s cheeks were also flushed red.

“Are you sure about this, Chika?”

Her response was cut off as the room’s gimmicks continued, but our proximity in that dimly lit, eerie room was already a haunting experience of its own.

“Hey, Takkun.”

“What’s up?”

“Takkun, have you ever kissed someone?”

“No, I haven’t.”

“Me neither. The closest I’ve come is a peck on the cheek from my mom when I was little. So… um…”

Fidgeting, she trailed off, her words muddled.

“…I’d like it if you did it, Takkun. I don’t really know how.”

──She said something like that.

In the darkness, amidst the eerie sounds around us, my rationality began to numb further.

Right, it’s for the exorcism. It’s unavoidable, a force majeure.

Even such flimsy self-justification was readily accepted by my mind at the moment. As if being controlled by something, I leaned towards Chika to kiss her─

“Ah, time’s up! Damn, the evil spirit is fully awakening now… gwaahhh!!”

Just as I was about to do it, the man’s voice echoed again, and I hastily pulled away from Chika.

“Looks like we’re out of time!”

“Yeah, out of time, right!”

We both awkwardly said that, and then suddenly, numerous… hand-like things burst out from both sides of the room!


The slightly pleasant atmosphere from moments ago was shattered by Chika’s thunderous scream. Simultaneously, arms wriggled out from the walls and a ghastly face was projected onto the ceiling using what seemed like projection mapping.

Even I was startled by this, partly because of its technical impressiveness.

And, of course, Chika was utterly terrified.

“Meeaaaahhhh! The face! On the ceiling!”

Her scream, louder than the metallic noise, was met by an ominous, deep voice.

“I won’t forgive, I will kill, kill…!”

Then, the room filled with mist, red lights flashed, and part of the ceiling opened like an elevator, revealing a figure descending.

It was a woman crawling on all fours, with long black hair. But what was truly bizarre was her back, sprouting numerous gnarled human arms.





In this battle of screams, Chika unsurprisingly lost.

She collapsed to her knees, staring blankly into space, motionless.

“Hey, Chika? Are you okay?”

I rushed to her, waving my hand in front of her, but there was no response. It seemed she had fainted from shock.

As I wondered what to do, someone tapped my shoulder from behind.

“Um, is that guest okay…?”

The actor playing the spirit, with arms protruding from her back, asked with genuine concern.


“Umm, huh…”

“You’re awake. Good.”

As Chika woke up on a white bed, I greeted her. She looked around, confused.

“Where are we?”

“The amusement park’s first aid room. You fainted in the haunted house, so they let us use this place.”

By the way, the actor playing the spirit helped carry her out. I couldn’t thank her enough.

As I explained, Chika pulled the blanket up to her mouth with a disheartened expression.

“…Ugh, how embarrassing. I thought I was overcoming my fears.”

“It’s okay, that was quite a performance… I was a bit scared too.”

Trying to comfort her, Chika remained unusually downtrodden.

Seeing her like this, I thought for a moment, then went to the small fridge in the room and took something out.

Seeing it, Chika exclaimed, “That…”

It was an ice candy from a nearby shop, shaped like the park’s mascot character, in orange flavor. I handed it to her and smiled slightly.

“You used to beg for this when we came here before. I wasn’t sure if you still liked it, but I thought it might help you relax.”

Feeling suddenly embarrassed, I averted my gaze.

Seeing me, Chika sat up, took the ice candy, and smiled softly.

“Thanks… You remembered.”


I replied shortly, trying to hide my embarrassment. “But,” she continued with a calm expression,

“You got one thing wrong, Takkun. I did ask for it, but initially, I couldn’t get it.”

“Really? I thought…”

I distinctly remembered her holding it with a big smile as a child.

As I looked puzzled, Chika smiled again.

“It was exactly like this back then. I was paralyzed with fear in the haunted house, and you helped me… Then, with the little pocket money you had, you bought this for me.”

“Was it like that?”

Her words brought back a clear image of her as a child, clutching the ice candy and smiling.

As I tilted my head, Chika chuckled softly.

“Yeah. You were always there for me, Takkun.”

“Yeah, that’s right.”

I thought I remembered the past well, but it seems that wasn’t quite the case.

“Chika, you’re really something.”

As I shrugged my shoulders, Chika responded with a mischievous look.

“Hehe. I’ve always been watching you, Takkun.”

I knew she meant nothing more by her words, but still…

Being told something like that by such a beautiful girl, any boy would feel a certain way. I wished she’d be a little more mindful of how her words affected me, as my face turned red with embarrassment.

“By the way, what happened inside again? I barely remember anything before I fainted.”

“It’s better if you don’t worry about it.”


“Please, just don’t think about it.”


Earlier that day, in Ashihara Fantasy Land, around mid-afternoon.

Among a group of high school girls, one girl stood out for not being as enthusiastic as the others. She cast her gaze over the passing crowd.

One of the girls approached her with a high-spirited tone.

“What’s up, Matsuri? You look down.”

“Ah, no? I’m totally up and excited.”

Though she smiled and responded, when unnoticed, she couldn’t help but sigh.

It’s not that she wasn’t having fun, but… there was someone else she wished was there. Just thinking about him made her feel incomplete.

“Lately, he’s been kind of distant…”

With a sigh, thinking about “him,” she couldn’t help but feel a bit down, even though she didn’t want to show it in front of everyone. As her gaze wandered aimlessly…

That’s when she saw her. Amidst the crowd, a girl with striking silver hair caught her attention. The girl, in the company of someone else, walked with a familiar smile. It was her classmate, Kurokawa Suvuetorāna. But what drew her attention more was the person walking beside Kurokawa.

“I thought they might be siblings, but no. He’s someone I know very well…”


Surprised, Matsuri muttered to herself in disbelief.


After Chika recovered and we thanked the staff, we left the first aid room.

As it was still early in the afternoon, we decided to enjoy the attractions without any thoughts of training. By the time it was evening, we were back home.

We had dinner as usual, took baths as usual, and went to bed as usual.

Despite the fun day, I was overwhelmed by exhaustion and sleepiness. I started dozing off around ten, which was unusual for me.

I thought I should go to sleep early, so I closed my eyes, letting the drowsiness take over, but…

“…Hmm, it’s not working.”

Around midnight, I found myself wide awake again.

I had gotten into bed feeling great, but as I lay there with my eyes closed, I unintentionally started recalling the day’s events, particularly the sensation of holding Chika’s hand.

Don’t judge me. Guys like me, who aren’t used to being around girls, tend to overthink these things.

I had managed to keep my composure in the haunted house environment, but now, in the quiet of my room, I couldn’t help but feel restless.

Just when I was starting to get used to Chika living with us and not overthink things… What a pitiful trait of a boy.

As I tried to shake off these distracting thoughts and closed my eyes again, that’s when it happened.

Someone knocked gently on my bedroom door.

At first, I thought I misheard, but no, it was real.

“Takkun? …Are you awake?”

It was Chika’s voice, soft and hesitant.

“Yeah, I’m up… What’s up?”

I wondered what she needed at this late hour. I got out of bed and opened the door.

There stood Chika, clutching a pillow and wearing pajamas.

“Sorry, Takkun, for coming by so suddenly at this time…”

“No, it’s fine… But what’s up?”

To my question, Chika, burying her face in the pillow and averting her gaze, muttered softly.

“…I’m scared.”


Still not fully grasping her meaning, I was taken aback when Chika, seemingly losing patience, clarified.

“Because! I keep remembering that haunted house and I’m too scared to sleep alone!”

“Can’t sleep alone…”

Really, like a grade-schooler. I wanted to retort but restrained myself, seeing her serious demeanor. However, another question nagged at me.

“So, why did you come to my room?”

“Why? Because… well, that’s why. I wanted to sleep together tonight.”


Her casual mention of something so astonishing almost made me raise my voice in surprise. I quickly lowered it, remembering that my parents’ bedroom was on the first floor and unlikely to hear us, but still, it would be hard to explain if they suddenly appeared.

Trying to contain my shock, I sighed and looked back at Chika.

“Sleep together? Do you understand what that means?”

“What does it mean?”

Chika tilted her head in confusion. Right, she was always like this.

“By the way, Chika, how did you do in health and physical education tests?”

“Why? I’ve always scored a hundred, but what does that have to do with anything?”

What’s going on with the education in this country? In a moment of escapism, I posed this societal query, then snapped back to reality.

Wait a minute. She just said “sleep together,” not necessarily in the same bed.

My high school boy’s brain had run wild with the idea of sharing a bed, but it might just be a simple matter of her in the bed and me on the floor. Though, even that idea was stimulating enough.

With my senses slightly skewed by the late-night atmosphere, I tried to make sense of the situation.

“Sorry, I got a bit carried away… So, you mean sleep in the same room, right? That’s fine by me.”

“Really? That’s great…”

Chika’s face brightened up, and I nodded, continuing.

“Okay, then you can take the bed… But since I was just sleeping there, should I bring some blankets?”

“I don’t quite understand what you’re saying.”

“What do you mean? If we’re sleeping in the same room, we’ll split up, right? You on the bed and me on the floor.”

As I explained, Chika blinked in surprise and shook her head.

“No, that’s not what I meant. What I’m saying is… I’m scared, so I want you by my side when I sleep.”

“Next to you?”

Wait, does that mean…

…Apparently, that was indeed what she meant.

“Even so, that’s a bit…”

As I began to object, I stopped, seeing Chika’s genuine fear. Her shoulders shook with fright. After all, it was partly my fault for putting her in such a state during our “training.”

Should I then comply with her request?

After a moment of thought…


My back was warm.

Giving in to Chika’s request, we ended up sharing my bed. The first thing I felt was her warmth.

We couldn’t face each other, and lying side by side would be too awkward, so I turned my back to her. Of course, my bed was meant for one, so sharing it meant inevitable closeness.

I could feel Chika’s breath on my back, indicating she was facing me. She shifted slightly, causing our feet to touch briefly, and I quickly moved to adjust our positions.

Far from being able to sleep, my body was now fully alert.

You might find it silly, but sadly, this is how a high school boy is wired.

Sharing a bed with such a beautiful girl, feeling her body heat so close… It’s unlikely any high school boy wouldn’t feel restless in such a situation.

How was I going to survive this night… But just then, Chika suddenly hugged me from behind.

Not just her arms – a soft warmth pressed against my back, sending my entire circulatory system into chaos.

“Uh, Chika? What are you doing?”

“Just hugging you… it calms me down.”

“High school boys aren’t just pillows to be hugged, you know.”

“But… if we don’t do this, I’ll be scared.”

Ah, I see. If she’s scared, then it can’t be helped.

With a somewhat resigned self-assurance, I thought this, and then Chika spoke up softly after a while.


“I’m sorry, I’m sorry, I’m sorry.”

“Why are you apologizing?”

She calmly pointed out my reflexive apologies, and then Chika went on to say,

“You know, I’ve always wanted to say this but never found the right moment… Thank you for always joining me in my training.”

Hearing her words, I let out a small snort.

“…I haven’t done anything worth being thanked for. Rather, I should be the one apologizing to you, Chika.”

“Why? What for?”

She asked inquisitively, and after a moment’s hesitation, I confessed,

“For scaring you so much in the name of training. I might have inadvertently given you some weird trauma… I’m really sorry.”

When I honestly apologized, Chika fell silent for a while and then replied,

“That’s not true. Remember, I said any kind of training would be fine.”

“But still…”

“I absolutely want to overcome this fear. I need to. So… this is fine.”

Her firm voice left me speechless, unable to say anything more.

After a while, I ventured to ask her,

“…I’ve been wondering. Why do you need to overcome this fear so badly? It’s not like you’ve ever shown any weaknesses at school, and I think you’ve hidden it well enough.”

To my casual question, she replied a bit more sternly,

“I can’t allow it. I must cure my fearfulness… I promised that to you, Takkun.”

The last part was almost a whisper. Yet at this close distance, I didn’t miss it.

“A promise?”

To my query, Chika was silent for a moment before responding quietly,

“Don’t you remember?”


“…I see.”

Confused by her words, I asked again, but she just replied with that and then fell silent.


No more words came. She wasn’t asleep, but… she chose not to speak anymore.

The word “promise” kept spinning in my mind. As I pondered it, I eventually fell asleep, and when I woke up the next morning, Chika had already returned to her room. I got dressed and left my room, and just then, I ran into her, already in her uniform.

Considering what happened last night, I felt awkward about greeting her, but not doing so would be even more unnatural.

“Good morning,” I said, my voice tinged with a bit of unease. But…

She turned away from me without a word and descended the stairs.

True, outside of training, we weren’t exactly chatty. But we did exchange greetings like “good morning,” “I’m home,” “welcome back.”

Yet, this attitude from Chika was puzzling.

“Chika, hey—”

I called out to her, and she looked back once on the staircase, her face different than usual—no, perhaps it was her usual “princess” mode. She looked at me with a composed expression and said,

“I’m sorry, Takkun. I misunderstood.”


“I don’t need your help anymore. Thank you for everything up to now.”

With those dismissive words, she hurried downstairs.

Standing there, stunned by her words, I eventually snapped out of it.

…Despite getting up earlier than usual, I ended up almost being late for school as usual.
