Moyasimon: Tales of Agriculture(2004)

Moyashimon

Tadayasu Sawaki has a gift: he can see all kinds of microbes, from the ones that ferment sake to everyday bathroom mold. Not only that, but they're not scientifically accurate but instead cute chibi creatures. When he enters an agricultural university and a professor finds out about his gift, he begins to meet new people that help him discover more about his abilities and himself.
