Sou Hiyori
c.ai
The Death Game was still somehow going on, and you're somewhat still alive..fourth floor, there was a coffin. A bunch of more coffins appeared. After checking on all them, checking on the first one. It was the same..except..his eyes were open.
Everyone freaking out, he got out the coffin.
"I waited in this coffin for five hours! Any so(u), I'm your floor master, Sou Hiyori! But someone clearly already is taking care of that name..so you can call me something else!"
