||Y/n's P.o.v||

 Suddenly the ground shook then entire school. Karma and I quickly pulled away and looked towards the window. He got up and held out his hand to help me up as well. We went over to the window on the other side of the classroom to see what was going on, and we saw smoke coming from he shed tha Nagisa, Koro Sensei, and Kayano had gone to. My stomach dropped, I had a bad feeling about it all.

"Do you think we should check it out?" He asked me.

I blushed, but before I could answer the ground shook again. This time, it was much more violent and I partly lost my balance. Karma grabbed onto me to make sure I didn't fall. He and I looked towards the window and saw Koro Sensei near a hole in the ground. He looked disheveled. Karma and I instantly looked at eachother, and he let go of me.

"Let's go..." I told him.

He nodded, and together, we both left the classroom and went outside to see what the hell was going on.

"Koro Sensei!" I heard Nagisa at the front of the class say.

Quickly, panic instilled in me and I quickly moved past my classmates to get to the front. My heart sank when I saw Nagisa leaning on Isogai's arm in support.

"Nagisa, are you okay??" I asked, also lending my shoulder for him to put his arm around.

"Yea...I'm okay..." He told me.

"What in the world was that just now??" Isogai asked Koro Sensei.

No words were needed to be spoken for us to understand what had happened. The roof of the storage shed was blasted open, and out came Kayano, she stood on top of the shed. She looked different though. Her hair was longer and her eyes looked cold. The biggest difference about her though, was that she had freaking green tentacles coming out the back of her neck!! I eeked in surprise and tried not to recoil in fear. 'What the hell is going on??' I thought. She stared down at as all as if we were ants on a farm, it was seriously intimidating and not at all how I was used to seeing her face. "Kayano...?" I heard Kanzaki say, "What's with those tentacles..."

Kayano smiled and said,

"Aw man, I attacked you with all I had, too. I can't believe I let him get away.Must have underestimated him."

Koro Sensei stood up and looked at her,

"Kayano, what in the world...?" He asked her sternly.

"Sorry, Kaede Kayano's not my real name. I'm Aguri Yukimura's little sister." she told him.

Koro Sensei gasped and I thought about what she said for a second. Aguri Yukimura...? Why did that name sound so familiar? I was sure I had heard it before, but where, it escaped me. I cursed my intuition for being nowhere to be found when I needed it the most.

"You understand now, don't you?" She asked Koro Sensei, "Murderer."

"Yukimura..." Hara clasped her hands while she said it.

Nagisa took his arm off my shoulder, but I was too busy staring a Kayano's eyes to care. Her eyes, they looked so full of hatred. This new version of her, scared me, but at the same time...Seeing the real Kayano...It was inspiring. This girl, I didn't hate her like I did Kayano. This person was someone else entirely, and she was lowkey...a badass...

"It's no use crying over spilt milk. I have to rest." She told us. "I'll try to kill you again tomorrow, Koro Sensei. I'll let you know where beforehand. Now that I've fought you tentacle-to-tentacle, I know for sure."

Kayano, loosened her tie before she began speaking to our teacher.

"I can definitely kill you as I am right now..." She said.

Then Kayano left. She used her tentacles to propel herself out of there, and all any of us could do was stare up at her and watch. "What...the fuck..." I muttered to myself.

"Unthinkable." I heard Itona say.

I stopped looking at the sky and back at him instead. He then went on to explain that if she grew tentacles without any maintenance, she would have been under constant hellish pain. That there was no way she could bare it without having it show on her face...She did though, because none of us knew that she was like Koro Sensei and Itona until now.

"Not only that, but she's Aguri Yukimura's little sister?" Maehara added.

"Isn't that out old homeroom teacher?" Sugino asked.

I knew that I knew that name somewhere, damnit!! Of course I forgot the name of our old homeroom teacher though, I came like 40 minutes late to class everyday, then I slept for the rest of the time!! I felt like an idiot...And Kayano...wait, if she was trying to kill Koro Sensei in that shed just now, then that also meant... I gasped and covered my mouth. Oh no...I was wrong I had got it all wrong...This—everything I thought, it was all wrong. Nagisa wasn't cheating on me even though we aren't technically dating, he was probably helping her with something!! Of course I blew everything out of proportion, per usual, just like Karma said...Oh my God, Karma kissed me!! And I let him!! I don't even like him, so why, WHHYYYY would I kiss my crush's best friend!! I wanted to break out into sobs right there. No, I wanted to jump in front of a train.

I jumped when I felt someone touch my shoulder. I looked back, and just my luck, it was Nagisa. My face exploded with heat the traveled to my neck and ears,

"Are you okay, Y/n? You look really shaken up."

I looked away from him quickly, "Yea..." I told him.

"Are you sure?"

I paused, "No..." I told him. After saying this I felt all the color leave my face. I turned to face him and swallowed my pride. I knew it wasn't the best time to drop his bombshell on him, but there's no time like the present...He deserved to know...I needed to tell him.

"Nagisa...While you were gone, I—"

Someone bumped into me and put their arm around me before I could tell Nagisa the truth. Of course, it was Karma,

"N/n-chan...You should be listening to what the others are saying..." He told me.

I looked up at him him,

"But, I—"

Karma didn't pay any attention to me and instead looked at Nagisa. He gave Nagisa a harsh glare, "You too, Nagisa-kun..." He said in eerie tone. I felt a chill ran up my spine, something about the way he said that...It left a bad taste in my mouth.

I let Karma bring me back over to the rest of our classmates. Once we were there, I quickly pushed his arm off at me. I glared at him, but all Karma did was shrug. I huffed and looked over at Karma, getting ready to tell him off, but then Mimura said, "I thought I'd seen Kayano before somewhere." He showed us a picture of a girl who had the same harsh look Kayano had. She also had long hair like Kayano, only it was brown. "I remembered after seeing her with her hair down and her harsher expression. Do you remember Haruna Mase?" He asked. He then went on to explain that she was a young acting prodigy who could easily take on any role, but it had been a while since she left the entertainment business which is why he didn't recognize her. I vaguely remembered her as well, but just as he said, it had been a while, so seeing her with short green hair and a kind expression, I didn't suspect a thing.

To me, it made sense why I didn't like her. Sure, I was jealous of her relationship with Nagisa, but I never fully thought that was the reason why I didn't like Kayano. There was always something else about her that just pissed me off...Could it have been the fact that she was hiding the real her? And what did she mean when she said Koro Sensei was a murderer. I had so many questions...

Man...This day just keeps getting worse and worse...
