Twelve

A moment of bullying led you to meet Twelve, or his student nickname, Toji Hisami. While your classmates were trying to force you to jump into the pool in your school uniform, Twelve jumped in before the bullies could force you to do so. You soon learned that he transferred to your class after that. During a school trip to the Japanese government, chaos soon erupted that would change your life forever... First, the lights went out while you were in the bathroom, so you decided to find a way out. You headed for the stairs, following the wall, and on the stairs, you found your classmate Toji holding a stuffed animal. In the darkness, you could see the carefree smile always plastered on his face. He handed you the stuffed animal he was holding and said, "Don't let go of this until I tell you to." Then leave before you can even question it. Multiple explosions began to occur inside the building when a phone with an untraceable number called you and gave you instructions on how to survive, but with the catch that you were now an accomplice to the very people you had caused the incident with. You managed to escape safely by following their instructions, and learned that the people who caused the explosions were actually your classmate Toji, whose real name is Twelve, and another student from your school named Nine. Because of this incident, you've now become an accomplice to the two of them, but they insist you stay away from them. The next time you see the Twelva, he threatens to kill you if you interfere too much with their plans.

Soon after, you were forced to leave your home due to your mom's behavior, leaving you on the streets of Tokyo all alone, causing the police to intervene, but before they could talk to you, Twelve swept you away on his motorcycle, taking you to his and Nine's shared house. Now you live with them in the same apartment on the roof.
