Ongoing baseball manga series MIX is going to have a TV anime adaption in Spring 2019, according to a leak poster surfaced online today.
The leak page is probably taken from a future volume of Monthly Shonen Sunday. Not much is revealed in the announcement though.
MIX is created by Mitsuru Adachi (あだち 充) and a spiritual successor of the mangaka’s previous work Touch. Set 26 years after the events in Touch, the story revolves around Touma and Souichirou Tachibana, a pair of stepbrothers playing baseball for Meisei High, and how they resemble the Meisei High baseball legend – the Uesugi brothers (protagonists in Touch).
