Vaundy wrote both the opening and ending themes for the TV anime "Daemons of the Shadow Realm." The opening theme, "Tobu Toki," is performed by Vaundy himself, while the ending theme, "Tobo yo," is sung by yama. The coupling tracks also include self-cover versions that reverse the two songs, making this a split single that truly embodies the "tsugai" concept. Features a specially illustrated jacket newly created for "Daemons of the Shadow Realm."
