I feel like I'm forgetting someone important... Yuuma Kurose is a lonely boy who can see ghosts and is plagued by nightmares. In his dreams, he is returning to his hometown and there sees Kaito, a boy surrounded by terrifying spirits. For some reason unbeknownst to Yuuma, Kaito runs after him with a serious look in his eyes, saying, "I'll definitely protect you." The same moment he touched him, the spirits that have been surrounding Kaito start possessing Yuuma all at once! A strange and youthful tale of two people who are at the mercy of fate!
