Hainiwa

Hainiwa is the protagonist of A Classroom Bereft of Angels and was a childhood friend of Amane's. They met during kindergarten, where Amane grants her wish of A to stop picking on her. Afraid of what Amane could do to her, she refuses to tell anyone about the deaths or confront her.

During high school, Hainiwa stands up to Amane to figure out the truth behind everything. Amane proceeds to throw her off the school roof, killing her, which then causes Hainiwa to spend her afterlife watching over her.
