Yo-kai Watch Shadowside animation series
Decades before the events of the series, Kamamoto used to be a human who worked as a potter, before becoming enamored with the idol industry, thus quitting his job to become a producer.
After a few successes, his idol group was quickly overshadowed by Next HarMEOWny, and the resulting sadness and anger managed to turn him into a Yo-kai.
In SS015, he is shown to be turning girls into dolls in order to control them, so he can try to build a perfect idol group.
In SS020, Atushi Kamamoto is summoned, along with Natsume's other Yo-kai friends, in order to watch Filmlin's movie. When the movie begins, he runs out of the room due to the scariness of the movie.
Atsushi Kamamoto is a play on Yasushi Akimoto, and combines atsui (Japanese: 熱い "hot") and kamamoto (Japanese: 窯元 "pottery").
Kamadouma comes from (Japanese: 𥧄 kamado, "furnace, kiln, oven"), (Japanese: 𥧄馬 kamadouma, "cave cricket", translated to "furnace horse") and (Japanese: 魔 ma, "demon").
Atsushi Kamamoto is a parody of Yasushi Akimoto; the creator and producer of several idol groups such as AKB48, which Next HarMEOWny is based on.
