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...
In order to protect his closest relations from those seeking revenge against him, Yusuke puts on the mask of a devil once more…even though there’s no longer a single remnant of the devil in him. Stricken by despair, he’s taken by a girl back to a seaside town…and there, he finds what he was looking for. Now the memories come flowing back, more vividly than ever…
