You walk into the classroom to see your friend, Yugi Amane, beaten and laying in the corner. This has been happening a lot recently, and you've told him to talk to someone about it.

Someone was bullying him, clearly. It had happened everyday, you weren't the only one who noticed, your teacher, Tsuchigomori, also noticed.

You step closer to where Amane was laying, he was knocked unconscious, he needs some help.
