No One's POV

So far, class 3-E has gotten close to their new art teacher, and now, they even call her Kai-Sensei.

Their relationship is one filled with trust and respect (and fear, if they somehow get on her bad side *cough* Terasaka *cough*) but the students still don't know that much about her. She is still a mystery.

As for the teachers, well... nearly each day Professor B***h would always try to hug Kaitlyn, but only for Kaitlyn to dodge and avoid it. She explained to them that she doesn't really like hugs much, but still Professor B***h try's because 'Kai-chan is just too cute not to hug!' Was her reasoning and motivation.

Kurasuma would simply be Kurasuma, nothing much about him, he still keeps his distance to keep this professional, but in truth he likes the small adult, just in the short amount of time Kaitlyn's grown on him.

As for Koro-Sensei well... Kaitlyn and Koro-Sensei share a lot of things, each of them loves to teach, and they recently found out that even Kaitlyn can be just as odd as he was, which strengthened their friendship.

But when Koro-Sensei tried to do his perverted things he was scolded by Professor B***h and everyone in class. Reason was because between everyone here, Kaitlyn was the most innocent one. (She doesn't know anything, about rude stuff. A lot of her friends try everything in their power to keep it hidden from her, even to this day)

...~...~...~...~...~...~...~...~...~...~...~...~...

Irina and Kaitlyn were walking along the hallway ~ after Koro-Sensei did his perverted thing and looked a Irina's chest. Irina took Kaitlyn with her, away from the perverted octopus, and started chatting, until Kaitlyn stopped.

"What's wrong Kai-chan?" Irina asked, worried about the small adult.

Kaitlyn could sense something was wrong and pulled Professor B***h behind her, just before a rope/wire wrapped around her neck.

"Look buddy, I don't take 'trying to hurt my Onee-san' likely, so hurry and show yourself!" The ravenet demanded.

Dark brown eyes narrowed as a figure came to view.

"I see, you are quite skilled now aren't you young one" a shady looking old man with black hair said with amusement.

Then Kurasuma came, and recognised him.

"Kurasuma, do you know this man?" Kaitlyn asked ~ more like demanded ~ him, while still staring at the intruder.

"Yes, this is..."

"Lovro... my teacher, a retired Assassin, one of the best that works for the government. He is also the one who assigned me on this mission" Irina explained nervously, gritting her teeth.

"Correct, and I'm here to take over this job, Irina you run along home, you are clearly out-matched" the man known as Lovro said to her.

"Please sir, you have to give me a chan-"

Before she could finish, in an instant Lovro's hand was out stretched, ready to grab her, but one small hand stopped him and held on to his arm tightly.

Kaitlyn held on to his arm tightly, eyes still narrowed underneath her fedora, glaring at the man.

"Hm... you've got quite the protective friend Irina, don't worry child, she knows how to take care of herself" reluctantly, Kaitlyn let the man go and moved aside.

She knew it wasn't her business, but can't help but protect her friends.

"Irina, what have I told you, 'everyone has their own strength and weaknesses' a good assassin knows when to go home."

"Congratulations! You are half wrong and half right!" Koro-Sensei appeared, his face half purple and other half orange.

"I agree as an assassin our beloved Irina is nothing special, frankly she's crap"

"NO ONE WAS ASKING YOU!"

Kaitlyn mentally chuckled at the bluntness of Koro-Sensei.

"Having said that, she belongs here, she's a perfect fit for this class" Koro said, and Kaitlyn couldn't help but mentally agree.

"I propose a kill off, let us see who passes as the better assassin! The rules are simple, whoever kills our friends Kurasuma and Kai-chan firs... ugh? Where did Kai-chan go?"

Everyone look to the spot were the long haired ravenet stood.

'What the hell! She just disappeared with out a sound or us realising!' They mentally thought.

Then Koro found a note from Kaitlyn on the ground and opened it.

Sorry Koro-Sensei, but count me out of this game, not really in the mood

~ Kai-chan 😄✌️

"Oh well... I guess Kai-chan won't be participating, what a shame. Anyway whoever kills our friend Kurasuma WINS!" Koro continued his announcement.

"Excuse me, Why the hell am I the only target all of a sudden" Kurasuma complained.

"It has to be you, I am un-killable and Kai-chan just ran out." He explained then handed anti-sensei knifes "here, you have all day tomorrow"

...~...~...~...~...~...~ (Time Skip: the next day) ~...~...~...~...~...~...

It was the next day and Kaitlyn has been watching everything that's being going on ~ secretly of course. Irina's attempt on Kurasuma the first time made Kaitlyn sweat drop.

'Sorry Onee-san, but he's not the kind of guy to fall for something so obvious.'

As for Lovro Kaitlyn had a gut feel he's going to make a move in the Teachers break room.

And what do you know... she was right.

She stayed seated not really paying attention because she knew that, even though Lovro is a great assassin, Kurasuma is still young and highly trained, there's a reason why Lovro is a retired assassin.

After Kurasuma stopped Lovro, Kaitlyn gazed at her Onee-san and she look even more nervous ~ but not as nervous and scared as Koro-Sensei.

'I wonder why he's scared?' She mentally questioned.

Then Lovro spoke "Even if I wasn't a relic, even if I could kill that man, you'll still be out of my reach, same goes for Irina, if I can't do it then neither can she" he said to Koro and everyone heard him.

Kaitlyn finally stood up fedora shadowing her eyes "If that's how you feel Lovro-san then fine, but at least stick around to watch her, you'll see, my Onee-san can be more than just a pretty thing." Kaitlyn said eyes finally revealing themselves at the end.

Lovro looked into those dark brown eyes and saw the young looking adult meant every word.

"We shall see." and he walked out the door.

"Ka- kai-chan, did... did you mean it? What you said before. Do you think I could take out someone like Kurasuma." Irina asked stuttering a little.

Kaitlyn looked to her in the eyes and gave her a sincere smile.

"Of course, the same goes for you too, right, Koro-Sensei?"

Kaitlyn looked to the yellow creature with a knowing smirk.

"Kufufu, correct" he answered.

"I'll be off now, got a class to teach after all" she waved and left.

...~...~...~...~...~...~...~...~...~...~...~...~

The fedora wearing ravenet seated down eating her lunch with her class when she noticed everyone gathering towards the window.

She watched ~ along with the class ~ as Irina try's to assassinate Kurasuma. Getting the drop on him and holding the fake knife ready to kill, but he held her back.

In the end though, he gave in and she won.

The class cheered.

'I knew you could do it Onee-san' Kaitlyn smirked as she tugged her fedora down.
