Moyashimon

Sawaki Tadayasu has just enrolled in an agricultural university in Tokyo with his long-time friend Yuuki Kei. Although not known outside a close circle of friends and family, Tadayasu has the unique ability to see and communicate with microbes, which appear larger and look different to him than they do to a normal person's eyes. 

This catches the attention of Itsuki Keizou, a professor at the university and an old friend of Tadayasu's grandfather who specializes in microbiology and fermentation. Thus begins Tadayasu's tutelage under Professor Itsuki, aided by his graduate student Hasegawa Haruka, as he attempts to adjust to his new life at the university.

Note: Won the Grand Prize for the 12th Tezuka Osamu Cultural Prize and the 2008 Kodansha Manga Award for general manga.
