A disoriented young man awakens in an unfamiliar room, his mind blank of any memories or even his own identity. Six concerned maids attend to him at once, explaining that he is their new master and confirming his name as Akio. He soon discovers he is confined to a special mansion and may depart only after confronting unresolved personal matters, with the maids prepared to guide him. Lacking any recollection of what those issues might be, Akio faces an uncertain beginning in this strange new setting.
