   Summary

   Sawamura Eijun is loud, reckless, and obsessed with baseball—or so everyone thinks.

   But when he mysteriously disappears on off days, even his closest teammates start to notice something strange.

   What no one knows is that behind that carefree grin lies a mind far beyond his years: a genius scientist, internationally recognized, capable of accomplishments most adults could only dream of.

   And yet, for Eijun, none of that compares to the thrill of the mound, the crack of the bat, and the dream of standing at Koshien.
