Edit: Okay I have been informed that he was actually a human once, therefore this comment's wrong. Gonna leave it here for context though.
Not once did anybody or anything so much as try to claim that Kokoro (maybe? Been a long time since I've seen assassination classroom) is a human.
The entire schtick of that series is that he an alien
@Slovak Guy , I give he mentioned at season 1 that he was once a human but he doesnt tell people how or why he became the way he is.
@Enormous fire after checking the wiki, I found out that you really are right, he was actually a human. My bad, it's been a long time since I've read it
@Slovak Guy , it's all good, been awhile since I watched it anyways.
