Starting in April 2013, a one-minute short anime aired during the popular Fuji TV program "Numeron" (ヌメロン). This anime does not have its own dedicated webpage, and there was no official promotion prior to its broadcast. Apart from the anime itself, the only known information is the production company (DLE) and the voice cast. It is worth noting that the planner of the "Numeron" program—Atsuya Takase—is also an anime program planner who has been involved in numerous anime productions such as "Library War" and "Honey and Clover."
