The Assassination Classroom is real?! (Various x reader)

I meet Itona!

I turned around and speed away. I need to calm down...

"Hello?" I called Karasuma
"{Y/n}? Why are you calling me in the middle of class?"
"Because if I don't I'll end up killing them." I bit down on my tongue
"Who? Don't do anything rash"
"The kids name is Itona but not him but his guardian...that bastard is who I wanna kill..."
"Why? What's so special about him" he sounded confused
"He's the one who turned sensei into that thing! He has plans in the future...I wish I can stop it now..." damn it!!! No fair
"Why can't you?"
"Because it'll ruin everything that's gonna happen, I will mess up time and space if I interfere.. remember when I said that I don't want to be another Koro-sensei?"
"Well he is the one who turned sensei into that perverted octopus."
"I don't understand?" I can picture him pinching the bridge of his nose
"I don't have the right to tell you but...Koro-sensei wasn't born the way he is now...he was once a human and a very powerful one at that. He's what you Japanese call the Shinagami if I'm correct, and Itona guardian is a scientist who changed him into that thing, sensei was the only person alive who'll be able to handle this experiment and that's exactly what happened. But it went wrong and the former class E teacher who was also involved got killed .." I can hear Karasuma sighing in frustration with the new information. 

"The only reason I'm speaking in English is so no one over hears me."
"Makes sense...we will talk more later."

I nodded "What flavor cake you want me to bring home?"
"Just get me a chocolate, and have only 1 cake before dinner!" I giggled at how protective he is
"Yes fine fine onii-chan"

I hanged up and went to a sweet store.

I looked along the different cakes they have.
Yes they have my favorite!!!

"Hi how may I help you?" The lady asked
"Yes I would like to have 2 strawberry cheese cake and a chocolate cake."
She looked at me with a confused look
"Uh one moment" she spoke English with a very strong accent

Then she went to the back and grabbed a lady with a badge that said 'Manager'

"Hello what is it you like?" Her English was a little better
"2 strawberry cheese cake and a chocolate cake please oh and a glass of milk" she nodded and grabbed the cakes. 

Once I paid she led me to a table where I sat near a window and she put a tray with the items on.

They went behind the counter and stared at me. "We don't get a lot of foreigners here so let's hopes she likes it" one said

I took a spoonful of the strawberry one and ate it. Hmmmm~ delicious!!!

I gave them a thumbs up with a proud smile and continued to eat.

I was enjoying the peace and quiet until I heard the chair in front of me move. I looked up with a confused look to see Itona.

He was there glaring at me, "Can I help you with something Itona?"

"Hmm how is it possible? You were just giving out such powerful bloodlust s few minutes ago now it seems that it never existed." He tried to figure it out.
"It's rather simple actually, I learned how to control it, however what you guys saw and felt wasn't me letting loose that wasn't nearly a quarter of what I got" I smirked once I saw his face.
"I have to prove that I am the strongest!" He started to get antsy.

Once I saw that I cut a piece of my cake and fed it to him before he can say a word. He was shocked at the sudden gesture but he ate the piece.

"I know how much you like sweets so I gave you some to try" i smiles and he looked at me with sweet eyes.
"Now you can't fight me yet, not until you get stronger." I pet his head and got up to walk out.

"I'll see you in class" I winked and he blushed.

I walked out the door with the cakes in hand ready to go back home.

"School finished by now so he should be heading home soon." I smiled thinking about it.

"Well well look who we have here? Class E scum!" Oh great just what I need.

I rolled my eyes and looked up to see Asano and his little gang.

"What do you want? I got somewhere to be" I slightly lied
"You cut class didn't you? You may be a foreigner but there are still rules" the guy with the classes said to me.
"Tch whatever go follow your tomato head of a leader" I pushed passed him to walk by.
"Damn you brat!" He pushes me without my realization Crap!

I waited to hit the floor but it never came. When I opened my eyes I was in Karma arms.

"Ehh didn't anybody tell you picking on girls is a no no" He grins and stands up.

The other guy flinches slightly.
"What's it to you huh?"
"Everything" he steps closer while the other guy steps back.

Just then I moved myself behind him and took a fork out from the cake bag and put it on his neck.

"Next time you think about putting your hands on me, I'll make your life a living hell" I shoved him aside and walked to Karma.

"What you doing here I thought you guys have training with sensei?"
"Yeaaa it got boring so I left" he shrugs
"Of course you did" I give out a small sigh
"Is this really new?" He smiles
I giggled "Nope!"

We both walked home since it was close to each others. He went to my place and we studied for a little and chatted until Karasuma came home.

3rd POV-

As Karasuma got home, he found Karma and {y/n} near the table and both of them sleeping.

He clenches the bridge of his nose "What am I going to do with these two" he sighs and picks up {y/n} and puts her on the couch as he does the same for Karma.

"There" he puts a blanket on them and goes to his office. There he makes a phone call to his captain.

"So about the plan B, preparations are set and we are ready to set up whenever you are"
