Bouida Haruto, a hardcore otaku with no interest in 3D (real) women, once appreciated figures from afar, accepting that "if you get into them, there's no turning back." However, when Nona, a character he loved from an anime called "Girls→Planetary Investigation" had a figure of her released, he ended up purchasing it. And then that night, the figure of Nona somehow came to life, and a couple-like lifestyle between man and toy began.
In her Junior High years, the pitcher Yomi Takeda was not able to get very far in a cross-school baseball tournament. Since the catcher on her team wasn't at her level, she couldn't use her signature move, the "Magic Throw," and eventually regretted not being able to use it. After Junior High, she decided to stop playing baseball and went to Shin Koshigaya High School, a school without a baseball club.
There, she found her long lost childhood friend, Tamaki Yamazaki, who used to play catchball with her when they were kids. Tamaki also played baseball during her Junior High years as a catcher, and could even catch Yomi's "Magic Throw!"
Their promise with each other during their childhood could now be fulfilled! Walking together on the road of baseball once again...
The story of the girls who love baseball will begin!
