ダンガンロンパ/ゼロ

Ryoko Otonashi cannot hold on to a memory for long, so she writes everything down in a notebook and reads it back to know who she is and where she has been. Yasuke Matsuda, the neurologist she grew up with, treats her condition and keeps her steady inside Hope's Peak Academy. Their arrangement holds until a girl who seems to be despair itself walks into their lives. Kazutaka Kodaka wrote this light novel as a companion to the first Danganronpa game.
