According to Moonphase, a TV series for Sano Tae’s 4-koma manga series, 「Morita-san wa Mukuchi」, has been green-lit for production. It will premiere in July. The series had already received an OAD special back in March of this year.
Synopsis: (*courtesy of Desangel)
“Morita-san wa Mukuchi” is a 4-koma manga about Morita Mayu, a highschool girl who rarely speaks. The reason behind it is not because she doesn’t like to talk nor because she has nothing to say. The reason she rarely speaks is due to the fact she thinks too much before speaking, thus losing the timing to speak altogether .
