One might say that freshman college student Tadayasu Sawaki has a broad perspective. He possesses a peculiar ability to see microorganisms with the naked eye. Sawaki can perceive all sorts of microbes, from the fungi that cause athlete's foot to the yeast used in alcohol production, viewing his tiny companions as cute chibi creatures. Attending an agricultural university, his talent attracts the interest of numerous professors, including Professor Itsuki, who specializes in fermentation. Sawaki begins his studies indifferent toward his ability, having chosen an agricultural school in Tokyo. However, with the help of the eccentric community around him, he gradually learns to appreciate these visible microbes and his gift. The whimsical cast of professors and classmates at the university almost makes Sawaki seem normal despite his ability.
