Shoichiro Yamamoto Introduction to “Manemaneni-Nichi”

The latest work from Takuiro Yamamoto, creator of “Takagi-san”!
The latest work from Takuiro Yamamoto, creator of “Takagi-san: The Master of Teasing,” is a hybrid comedy blending everyday life and a touch of romance (?)!!

The story takes place in the baseball club at a certain high school. Experience the joy of everyday youth as the female managers bring life to the field!

Akane Nagisa became a manager simply because she thought it would make her popular—she knows absolutely nothing about baseball.
Karina Ichinose, who looks like a “gal” but became a manager because she loves baseball.
Yuki Himemiya became a manager because her boyfriend (at the time) was on the baseball team.

Making rice balls for the team, stumbling upon racy magazines in the clubroom, practicing swings with her childhood friend who’s on the team, and getting nervous during her first practice game…

As memories pile up for these three first-year managers, it’s time to say, “Play ball!”
