ONHA was originally a very simple idea. All that was needed was to craft a titillating hentai game based on the My Hero Academia Manga/Anime series, because we didn't want to go into something as elaborate as JPDE - Sonata of Fire... but, like many things in game development -even fan-games-, it spun out and become something else entirely. A compromise between those two extremes. ONHAcademia MINA is an adventure game featuring aged-up versions of the manga's heroines, now attending post-secondary education at UA Academy, going through a story which will explore themes and situations intended for a Mature Audience.

Mature here stands for: having reached a stage of mental or emotional development characteristic of an adult. The story will be from the point of view of Mina Ashido, as she takes a personal journey into the hidden side of the city of Musutafu, the Hero Business, and the society of 2055 Japan as a whole...
