Synopsis
Moyashimon follows Tadayasu Sawaki, a seemingly ordinary college freshman, who possesses the extraordinary ability to see microorganisms.
He enrolls in an agricultural university where his unique talent attracts the attention of quirky professors and classmates, particularly one Professor Itsuki.
Initially indifferent to his power, Sawaki gradually learns to understand and appreciate the world of microbes thanks to the influence of the eccentric characters around him.
The anime explores his journey of self-discovery as he navigates university life surrounded by these visible, chibi-like microorganisms and the unusual individuals who share his academic environment.
