"Quit playing up the deathbed angle." Shiro said, "You're still alive enough to dodge."

"Shiro..." Itona muttered.

"Useless girl. She'd give her own life for that revenge narrative of hers—you'd think she could have done a bit better than this." Shiro spoke.

Shiro then looked at Koro Sensei, who was starting to get up a bit and said,

"You're quite the monster. Just how many assassins have you driven away in a single year? But there are still two of them right here..."

As Shiro was speaking, he began taking off his cloth. I leaned forward a bit in anticipation. I really wanted to know what he looked like. After he removed the cloth and took off his mask I was in shock. He was a handsome man, but damn, HE HAD A FREAKING ROBOT EYE IN HIS RIGHT SOCKETT! I squealed in fright due to this sudden revelation.

"I'm the last one." He said, "You took everything away...and I'll make you pay for it with your life."

Shiro then looked at the cloaked figure in back and patted his shoulder before he turned around to leave, "Come, 2.0." Shiro said, "March will bring a perfect death for an accursed life. A chill ran up my spine as they quickly left. 

Once they were gone, I heard Yada ask what was up with Shiro and that Black clothed guy. No one was able to dwell on this thought, because Kayano had woken up. Slowly, she opened her eyes and in those few seconds, out class huddled around her. Even I got close to the crowd to see if she was alright.

"I..." Kayano spoke.

"Kayano...thank goodness." Koro Sensei replied.

"Kayano...are you okay?" I heard Nagisa ask.

I jumped when I heard his voice. It was as if a needle had pricked me. I didn't like it and I wondered if this would be my new norm. I now wondered that every time I heard Nagisa's voice it would be a painful reminder of what was, and could have been...

"Uh-huh..." Kayano replied.

I peaked past some of my classmates shoulders and saw that she had looked away while blushing. I used to do that too, so it was easy to spot from far away. I quickly stopped peering over my classmates soldiers though, as I did not want to see anymore of them.

"Kayano..." Okano trailed off.

I assumed she wanted some explanation, and so that's what Kayano gave her as well. "It was pure bloodlust at first...But as I spent time with Koro Sensei, I started losing my conviction in that bloodlust. Like, doesn't this teacher have some circumstances I don't know about? And shouldn't I find out what they are before I kill him? But that's when the bloodlust in my tentacles swelled forth. They wouldn't let me not do it. How dumb. Everyone was genuinely enjoying their assassinations while I wasted the whole year on plain old revenge...." She explained calmly yet sadly.

I could feel my heart strings being pulled by the authentic Kayano even though I didn't want them to.

"Kayano..." Nagisa said to her, "Once you taught me this hairstyle, I stopped fretting about my long hair. And like you said, everyone liked the name 'Koro Sensei' we've been using it all year. It doesn't matter what you were after. We all made you our friend, together. No matter how much you suffered on your own, we can't let you say it was all an act—not all those days you were smiling there with us. Koro sensei promised to tell us everything once we were all together.He's not a saint. We know he doesn't always do the right thing. But let's hear him out—all of us, together." Nagisa finished his speech.

Kayano nodded, "Yeah... Thank you...I can stop acting now." She said. It took my a minute to realize that she was crying, but once she did I started tearing up again. I wanted to hate her, I wanted to hate Kayano so bad. I wanted to hate her for turning out to be evil, I wanted to hate her for getting kissed by Nagisa, but I couldn't bring myself too it. I didn't know why, but there was just something about this new authentic Kayano that made her unhateable in my eyes any longer...

I let go of Karma's hand to wipe my eyes before any real tears came out. Isogai then turned to Koro Sensei and said his name.

"Whatever's in your past...We'll accept it, as long as it's the truth." Isogai told him.

Koro Sensei let out a long sigh before he replied. I could tell that he was really dreading this moment.

Still though, he did as we asked.

"I wanted to never talk about my past if I could help it. But I see I have to. I don't want to lose your trust, the bond we share. This past summer, on that southern island, Mr. Karasuma said of Miss Irina, 'The better the assassin, the broader her skill set'. I think that's relevant here. This E Class is the first I've ever taught. Even so, I've managed to teach you just about every subject without a hitch.Why do you think that is?" He asked us.

Not even I could think of anything, not at first. However, it didn't take me long for me to finally get it. I let out a quiet gasp as I put two and two together.

"Don't tell me..." Takabashi said while he was pushing up his glasses.

"That's right: Until two years ago, I was the assassin known as the reaper."

The class gasped, but Koro Sensei continued,

"And one more thing....Even if you do nothing, I'll die in March. Either I die alone or the earth dies with me: That's the only part of the future an assassin can change."

And with that, out superhuman beast of a teacher began unlocking the human aspects of his past...
