The show's actual magic isn't the bacteria, it's watching a kid treat invisible microorganisms like roommates and accidentally become the most useful person in every crisis. You're laughing at fermentation jokes and bacterial puns one moment, then watching him solve real problems by talking to things nobody else can see. The comedy lands because it never winks at how absurd the premise is. It commits completely to the bit and builds genuine warmth between Tadayasu and his tiny, animated companions. This is what happens when a show trusts its weirdness enough to let it be genuinely funny without apologizing for existing.

Tadayasu Sawaki begins his first year at an agricultural university in Tokyo with a rare gift: he can see and talk to bacteria, fungi and other microorganisms, which look to him like cute chibi creatures. The microbes treat him as their friend and are rather noisy about it. He arrives alongside his childhood friend Kei Yuuki, and his talent soon draws the interest of several professors, among them Professor Itsuki, a fermentation specialist. Sawaki starts out indifferent to his ability, but the eccentric professors and classmates around him gradually help him value it. The comedy and supernatural elements come with an educational streak, as each episode closes with a short microbe theatre segment where the tiny organisms explain what they are and what they do.
