~Y/n pov~

We were still tidying up bits and pieces from the play we did.

Kaede accidentally spilt the beads, so her and Nagisa were cleaning them up.

Koro-sensei left the classroom, maybe to find Kaede and Nagisa.

It had been a long year and soon it would be coming to an end.

I wonder if we can beat Koro-sensei before the limit expires.

A crashing noise interrupted my thoughts.

It seems everyone else heard it too.

Just what had caused the noise?

I quickly ran outside, followed closely by Karma and a few others not far behind.

When my footsteps halted, I saw something no one would believe if they didn't see it for themselves.

Kaede was stood on top of the building and there were green tentacles coming out of her neck. Her green hair was long and flowed down to her waist.

It was like she was a completely different person.

She's been hiding this the whole time?

Koro-sensei was on the floor near us, covered in scratches.

"Koro-sensei!"

"What happened?"

She finally spoke, "Aw man. I attacked with all I had too."

"Kayano? What in the world?" Koro-sensei stared up at her.

"Sorry." She smirked, "Kayano Kaede is not my real name."

So, all of this, all the time we spent together, it was all just a lie.

"I'm Aguri Yukimura's little sister."

The octopus had a shocked reaction, from that I could guess he probably knew her.

"I'll try to kill you tomorrow Koro-sensei. I'll let you know the location beforehand." With that she left.

"Unthinkable. If she grew tentacles without any maintenance, she would have been under constant hellish pain." Itona stared at the spot 'Kaede' once stood, "There's no way she could bare it without it showing on her face."

"Aguri Yukimura's sister?"

"Isn't that our old homeroom teacher?"

So that's why most of the class thought the name was familiar.

"I thought I'd seen Kayano somewhere else before. I recognise her now I've seen her with her hair down and a harsher expression."

"Isn't she Haruna Mase?"

"You mean the young acting prodigy?" I exclaimed, "Just what else is she hiding?"

"Who knows?" Karma smirked, "This is an unexpected turn of events."

~*~

"Kayano called you a murderer..."

"What happened in the past?"

"I'll tell you everything about my past. But before that,  Kayano is an important member of E-class." The octopus stalked, "I'll tell you when everyone is together as a class."

We stood in the field, all of us were behind Koro-sensei and 'Kaede' stood across from him.

"So you came.." 'Kaede' smiled, "Then, let's end this."

"If you do not remove the tentacles, your life will be in danger." Our teacher tried to reason.

'Kaede' remained calm, "There's no use trying to make me lose my composure with a bluff."

"Kayano, was everything an act?" Nagisa looked hurt.

Of course he would feel hurt though, who wouldn't if they were in that situation.

"I want to avenge my sister." She ignored his question.

"Kaede at least hear him out!"

"Are you really okay with this?" Karma had no expression.

Itona spoke next, "Your body probably feels hot, with just the nape of your neck cold."

Suddenly, her tentacles set aflame.

"Shut up. Outsiders should be quiet." She was listening to reason.

'Kaede' attacked setting a big patch of the field on fire, she also managed to get a few of Koro-sensei's tentacles.

Everyone backed away.

She was out of control.

No one knew what to do.

But we have to do something, or she'll definitely die.

It doesn't matter if she kills the octopus or not, she'll die regardless.

Unless we find a way to stop her.
