The detective's plaything (Kuroba Kaito x high school detective! f.reader)

Prologue

《[Y/N]'s POV》

It was just another boring day. I hung out with Kaito-kun and my younger sister Aoko. Solved some cases and went home.

Locked up in my room researching Kaito KID again I faintly heard my sister groan. 'Probably problems with homework again.' I thought as I lazily got up from my sitting position of course not before finishing my choclate and walked towards her room.

I knocked expecting an answer, but all I got was silence.

"Aoko. Open your door." I quietly said as I waited for some kind of sound coming from the inside of the room. Again. Silence.

"I'm coming in." I suspiciously said as I slowly opened the door. There she was sitting in her chair, homework sheets sticking to her face, but most importantly... The smell of a laxative everyone knows very well.

I imediately take a look at my suroundings. The window is open, seems to be fresh since it had just rained and there are no sings of rain in the bedroom. A white feather was left behind, a note and a jewel the jewel Kaito KID stole during his last heist. 'So he did return it. I knew it'

I put my gloves on and take the jewel with the KID note I didn't bother to wake my sister up knowing she whould push herself till she collapses. I exit the room and go to the living room.

"Oto-san!" I call out to him.

"What is it, [Y/N]?" He asks, but when he sees what I'm holding his face reddens from anger.

"God damn that phantom thief! He got away again!"

"Oto-san calm down. At least I was right about him returning it to sister's room." 'But... I didn't think he whould do it when she was in there.' I think to myself as my frustration overwhelms me.

♤ The next day ♤

I was sitting in my seat eating my bento when Hakuba-san aproached me.

"Hey Nakamori-san! Can you come to a crime scene with me?"

'Why is he suddenly asking me to go with him? Usually he solves cases with ease.' Feeling suspicious of his sudden offer I put on a smile and agree with it.

"Sure, I'm free."

"Great then I'll wait for you at the main gate."

"Sure, but why so suddenly?" I put on an innocent face and tilt my head to the side a little bit, at the same time reading his reactions. No changes. At all. I mentaly curse. 'I can't read him at all. That's a Sherlock Holmes fan for you'

♤ After school ♤

"Sorry, I had to talk to the teachers about something."

"You were the one who called me here and you're late." I complain.

"Anyway let's get going. I hav-" He starts but I interupt him.

"You have to talk to me about something important, right? You were very obvious since you usually solve cases easily by yourself. And right now we are heading towards the place where Kaito KID's last heist was." I stop talking and wait for him to say something, but when he doesn't answer I continue.

"As far as I remember yesterday you just solved a murder in the opposite direction where we're going. And since you are very punctual you try not to get involved in any cases in the morning." Hakuba-san was silent for a few moments when he spoke.

"As expected from a detective as good as myself. Yes, that is true. Right now we are heading to the building Kaito KID's heist took place in."

"And why are we heading there? KID never leaves any traces it whould be kind of hard to track him like that." Hakuba-san chuckles.
