A new Saki spin-off manga called Someya Mako's Mahjong Parlor Food has been announced. The author is Mekimeki and it will be published in the Young Gangan magazine (like Saki) starting on the 7th of June. It looks like it could be a food porn manga with some mahjong elements. The serialization of Toki by the same author will also continue. Akio Translations will probably translate the first chapter, but afterwards I'm not sure.
EDIT: Spectacular Scanlations on Mangadex will handle the translation.
Mekimeki released this nice picture for the announcement (all credit goes to Mekimeki).
I
must say I'm very surprised at this development. I imagine most people
are. A new spin-off, yes. But Mako? And food? I didn't see that one
coming. In any case, this could be like a Kiyosumi side-story with
Saki, Nodoka, Hisa and Tacos having plenty of screentime. More than
they do in the main story nowadays. That's if the story takes place in the same year as the main story of course.
