Tarō Komori is a narcoleptic 14-year-old boy is the main protagonist. Tarō and his older sister, Mizuka, were kidnapped 11 years ago, on September 22, 1996. Only Tarō survived the incident. Since then, he has had recurring nightmares and vivid out-of-body experiences (OBEs). Tarō records these visions to try and make sense of it all. He seeks help from a psychiatrist to help him sort through the details and deal with the fallout of his childhood trauma. Tarō can not remember the face of his kidnapper and has flashbacks containing a black giant taking his sister away.
Once in the Unseen world, Tarō hopes to meet his sister so that he can clarify the past and come to terms with her death. Tarō seems to have romantic feelings for Miyako.
Spoiler!In the later episodes, he begins to believe that Miyako is the reincarnation of his dead sister, Mizuka. As a result, he thinks that to be the cause of his feelings for Miyako. However, that is later subverted as Tarō admits that Miyako is Miyako, and no one else, after all.
