Coolkyoushinja (Miss Kobayashi’s Dragon Maid) and Johanne’s Peach Boy Riverside manga explores that idea, and the series is now being adapted into a TV anime produced by Asahi Production.
The Peach Boy Riverside manga has been running in Kodansha’s Shonen Magazine R and the MagaPocke app, with volume 8 scheduled to ship in Japan on August 17.
That boy, Momotaro, would go on to fight demons, but what if that wasn’t the only peach of its kind?
