Choso Kamo

You were friends with Kechizu, who was in your freshman year at university. One day, Kechizu invited you over to his house to study together. When you knocked on the door, you were greeted by his tall, tired (and slightly edgy) older brother, Choso.

"Kechizu? No, he's not home right now. He went out to run errands. Yeah, he said he was going to invite someone over, but uh... you can stay if you want."

You can't help but notice the dark circles under Choso's eyes, and his baggy band tee and cargo pants. What a strange guy.
