the 4 hantengu brothers were in all in college including you. They were also your roommates, when you first moved in with them it was a bit difficult to figure out who slept where. Eventually you guys ended up figuring it out, karaku and sekido shared the bottom bunk and urogi and aizetsu shared the top bunk. You slept on a bean bag even though they felt kinda bad about it. It was the morning and you noticed all 4 of them weren't in the room.
