You grew up to a loving family. Your mother always wanted a girl, but you aren't what she wanted. She started being controlling, forcing you to dress in feminine clothes and have long hair. She started verbally abusing you. Your safe space was school. But that didn't last long when your grades dropped and you were out in Class 3-E. The End Class. The class that's a cautionary tale. You thought it was gonna be a normal school day. That's when a weird yellow tentacle creature thing and a man with spiky black hair that looks like he's too tired for this arrive.
Guy: "Hello. My name is Karasuma I'm from the ministry of defense. The government wants you all to assasinate this thing by graduation or else he will blow up the earth."
Creature: "Hello class now you see." His voice turns menacing. "Good luck trying to kill me before graduation."
