Assassination Classroom (various characters) x Reader (one shots!)

Itona x Reader (I'm stronger than you)

Spoilers spoilers... Why are there spoilers at the first part anyways?! XD but I'm gonna change the story a little bit from the anime/manga alright? I hope you guys won't hate me! If you don't know Itona... You should really check the anime and the manga right now...

<~><~><~><~><~><~><~><~>

"Nee nee Koro-Sensei..." "Ah, yes what is it (L/n)-san?"

Koro-sensei tilted his head to see a girl who was very polite around the class, she's a friendly nice person, so most of the people liked her 'before' until she fell into the E-Class.

"Is it true that a new student is coming here today? I heard it from Maehara.."

Koro-sensei nodded. "Well yes, didn't you received Karasuma-Sensei's message?" "Ah--!"

(Y/n) sweatdropped, she didn't notice of that at all, "uwaah... I forgot to check..." And then Koro-Sensei laughed. "Nurufufufu... (L/n)-San, are you alright~?" "Uu.."

(Y/n) threw a knife at him but it was easily dodged.

"Now now (L/n)-San, we shall go back to the class." "... Hai.."

~<few minutes later>~

... A silence spread across the classroom, all the teachers, students were patiently waiting for the new classmate, and then, a sound of door opening was heard.

"..." A white guy, yes, a clearly, white guy not showing his face, covered in 'whiteness (if that is even a word)' . Then, he took out his hand to... ... Summon.. A pigeon..? Which it caused everyone to be startled.

"Oh, ahahah, Did I scared all of you? Well I'm really sorry. And by the way, I am not the new student, I'm his owner."

Everyone sighed in relief.

Then Nagisa, "well, if that was only a trick, I think Koro-Sensei won't get scared by just that--... ......"

Koro-Sensei was in a corner, scared.

"Just a simple trick and then he gets scared?!" Everyone thought.

"By the way, I am all white so you all can call me 'Shiro'. So.. I think I'll bring Itona, your new classmate. Come in Itona!"

Few seconds later, a sound of a wall breaking behind was heard, everyone turned back to see a guy who was not even wet when it was raining.

"....... Now I proved that I'm stronger than that wall."

'At least come inside the door you bastard!' Everyone thought.

And then Karma chuckles and asked Itona, "hey, why are you not wet? You don't have anything in your hands, but not a single raindrop are not soaking into your clothes."

Itona looked around for a bit then stood up.

"You're probably the most strongest one in this whole class aren't you?"

Then he started to pat Karma's head.

"Don't worry, I won't kill you because you're weaker than me.." Then he went for Koro-Sensei, but stopped in front of (Y/n). He looked at (Y/n) for a while, which it caused (Y/n) to come back with all her senses coming back to her mind. And then blush surprised since Itona was there in front of her.

Itona looked away then went for Koro-Sensei, "... I will prove that I'm more stronger than you at the end of the class.... 'Brother'." "N-Nyu.."

".... Wai--.."

"B---B------B--BROTHER!!?"

Shiro chuckled, "I hope all of you become a great friend with him."

Everyone was still shocked of what Itona said, but quickly came back to their senses.

~<few hours later>~

Itona took his Jacket and Scarf off, and threw it away.

"Well.. Itona-Kun, we shall make a rule for this assassination, if you go out of the ring, you are out, if you hurt one of my student.. That is out too." Itona nodded, Shiro looked at Koro-Sensei and Itona, "alright... Now... BEGIN!"

Then just about a second, no, not a second, just with the slight move, Itona managed to get Koro-Sensei's arm off.

How? Well, that is simple.

"A tentacle--?!" (Y/n) gasped and looked at Itona,

There was a tentacle growing from his hair. "Itona-kun...."

Koro-sensei's face was pitch black, it was his anger. "Where did you got that tentacle from..?!" Shiro sighed. "Heh, who cares?" then Itona kept attacking and attacking, Shiro supported his assassination too, which it made Koro-Sensei hard to move around.

"Haah.. Haah.. Haah...." "Getting tired already Koro-Sensei?"

Nagisa looked down gripping his knife tight, close to his chest. 'Is Itona gonna kill Koro-Sensei? I know it's great but... ... We all wanted to assassinate Koro-Sensei...'

"Well Shiro-san.. You have managed to get to know my weakness... But you have not completely used them yet.." "Hah, who cares? My plan will go perfectly just like I planned, Itona, get him."

Then Itona charged into Koro-Sensei.

"..!!!" His tentacles were broken,

"The knife! ... Wait where mine..?" Nagisa looked around, then he noticed that Koro-Sensei must have used it.

And then few minutes later, Koro-Sensei have won. Yep. He won.

"Well Itona-kun, the strength isn't everything, you have to train and study well to be better getting to assassinate me, so we shall study together Itona-kun."

"... I... Lost..? I'm.... Weak..? ... No... I'm.... I'm..... S... Stronger than him..!!!"

Itona's tentacles were pitch black, his eyes was glaring into Koro-Sensei.

"Tch..." Then Shiro shot something from his arm, making Itona pass out.

"Ahh, I'm really sorry Koro-Sensei but I think He's gonna take a break from school a little bit." Shiro carried Itona then went out of the room.

~<few minutes later>~

"Koro-Sensei you had a little brother?!" "Hey Koro-Sensei what is your meaning behind this!?" "Hey explain it to us!"

Everyone was now gathering up to Koro-Sensei, (y/n) sighed and went outside to get out from the mess.

She looked up into the sky, reaching her hand out. "... I wonder why I came here in such a messy world... ... Huh..?"

Someone took her hand making her to sit, "you're--... Itona.."

Itona sat next to her, (Y/n) felt very awkward, but she felt calm at the same time. "Hey uh.. Didn't you went back into your house or something?"

(Y/n) looked at Itona. Itona looked at her back then shook his head. ".... What are you doing here then?"

'Wh-whoa--! He asked me back.. That's weird..'

"Just refreshing here.. I don't really like crowds of people in the classroom.. So I sneaked out and went here, I'll go back there eventually anyways, so you won't have to worry about it Itona."

(Y/n) chuckled and stood up.

"Well gotta go now, thanks for talking with me Itona--"

Itona grabbed her wrists with his tentacles, he patted her softly on her head.

"U-um... Th-thanks..."

(Y/n) was blushing madly but quickly fixed it, and then she went inside.

"(L/n)-San! Where were you?" "Oh nothing special koro-sensei... Ahaha.."

and then they started to fix their chairs and desks.

<~><~><~><~><~><~><~><~><~>
