Sawaki Tadayasu, a new first-year at Agricultural University, can see microbes; when he spots massive numbers of microbes pouring out of the ground, he suspects that a missing student, Hasegawa Haruka, might be buried there.

Sawaki traces Hiochi bacteria to a room where two upperclassmen, Kawahama and Misato, are illicitly brewing sake.

Professor Itsuki sends Sawaki and his best friend, Yuuki Kei, to steal vegetables from a university farm.

Mutou Aoi, who once held the title of Miss Agricultural University, is ready to take it easy now that she's back in Japan; then Sawaki spots a microbe on her that's infamous for causing food poisoning.
