Egokoro Nao is an art college student and one of the 20 chosen to participate in the Death Game. She is initially timid and shy and primarily stays with her teacher Professor Mishima, whom she idolizes to the extent of wanting to stand in anyone's way if they say negative things about him. She is a very emotional and clever person, and also cares about her friends, as shown when talking with Gin, Reko, or Sara.
