Yusuke Saito is a normal high school kid...well, normal enough, except that he can't remember anything from his life except the last six months. But when he starts to get confronted by people who insist they're from his past, who allege that he did horrible things to them...suddenly Yusuke's missing memories become crucial to remember. Otherwise, the skeletons in his closet may just make him a skeleton, too...
Tracing the remaining fragments of his memory, Yusuke visits the seaside town he lived in with Akari Ichinose, the girl he hurt so badly. Then everything is revealed--his life with Akari, his memories of murder, and the facts behind his disappearance. The truth weighs heavily upon Yusuke, who thought he was detached from his own past...but there is no escaping the crimes he committed.
