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.
