Manga creator Roots announced on Sunday that a fourth season of the anime adaptation of his and artist Piyo's Teekyu tennis manga has been green-lit. The announcement was originally made at the Teekyu High-Fiving Party event on Sunday.

Piyo launched the manga in Earth Star Entertainment's Comic Earth Star magazine in early 2012, and the first anime season was announced just months later on the manga's first book volume. Earth Star Entertainment claims that this is the fastest television anime adaptation ever. A second and third season followed, with Crunchyroll streaming both series as they aired in Japan.
