The new updated version will have a voice cast, which includes:
Hazumu Sakuta (Sumikko Gurashi Sorairo no Mainichi, Eiga Sumikko Gurashi: Tsugihagi Kōjō no Fushigi na Ko) is directing the anime at Fanworks. Yoichi Kato (The IDOLM@STER Million Live!, Yo-kai Watch) supervised and wrote the scripts. Michihiko Suwa (Case Closed, Inuyasha) is the production planner.
Yoko Usami directed the first short series at Fanworks.
The company teases the series as a “cute x mystery” anime. The “authentic mystery” story follows Tomanto and friends as they solve mysteries using vegetable and fruit trivia. (Tomanto’s name is an apparent wordplay on the words “tomato” and “mantle” or manto, for the Inverness cape popularly associated with the Sherlock Holmes character.)
The first short series premiered on TRAIN TV, the video platform on Japan Railways trains’ in-car displays, in October 2025, with the 26th and final episode slated to premiere on April 5. The shorts stream on the TRAIN TV website and YouTube after they premiere.
