Tamanchu!
A story of Okinawan girls chasing Koshien — the summer we can't forget.
Set in Okinawa, Tamanchu! follows Aria Tamaki and her teammates as they chase a place at Koshien, the storied stage of Japanese high school baseball. Together, they race through an unforgettable summer of conflict, pain and growth.
Tamanchu! is a “Craft IP”: a story made carefully and grown together with its fans through conversation and feedback. The path is not fixed; the characters’ choices and the story itself can evolve in response to its readers.
In July 2026 we launched the official website, introducing the world and characters of the series. The novel itself is serialized on our official note.
