For some reason 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! Then an old man, Professor Itsuki Keizou, leaps onto the scene and starts digging...

Hiochi bacteria, sake's worst enemy, are pouring out of the window of a school building! Sawaki traces them to a room where two upperclassmen, Kawahama and Misato, are illicitly brewing sake. Now deep in debt after their sake brewing effort failed, the pair devise a plan to make money using Sawaki's ability to see microbes...

Kawahama and Misato have begun to cultivate caterpillar fungus to make money, but another first-year student, Oikawa Hazuki, kills them all with an antibacterial spray. Elsewhere, Professor Itsuki celebrates the construction of his new fermenting cellar with a sake brewing demonstration, giving Sawaki a firsthand look at the work of microbes in fermentation.

Professor Itsuki sends Sawaki and his best friend, Yuuki Kei, to steal vegetables from a university farm. The pair are on edge as they set out for their first thieving experience... but it turns out to be part of a campus-wide event using first-years to teach potential thieves a lesson!

Sawaki encounters a "microbe monster," a man covered from head to toe in microbes. He turns out to be Hiyoshi Kikuji, a friend of Professor Itsuki's who runs a liquor store. Sawaki and his companions are fascinated by Kikuji's tales of the depth of Japanese sake and the work of microbes. Just then, a woman bearing a huge backpack and a horrible stench, Mutou Aoi, appears...

Mutou Aoi once held the title of Miss Agricultural University, but after returning on foot from a long trip with a bag full of fermented foods on her back, she's lost much of her feminine appeal. She's ready to take it easy now that she's back in Japan, but Sawaki spots a microbe on her that turns out to be one of Asia's top 5 causes of food poisoning!
