Meet Sawaki Tadayasu, second son of yeast preparation suppliers, who is forced to go to an agricultural university and continue the family business. He has the unique ability to see microbes, and so he and his friend, Kei, are taken as students to the fermentation-process obsessed Itsuki-sensei. This manga follows Sawaki as he tries to make his way through university as discreetly as possible…which is pretty impossible if you’re as talented as he is.

A collection of eleven short stories with a wide variety of subjects.

Maria is a witch living during the Hundred Years' War between England and France. Our young heroine hates war, so to keep the people of the village she protects safe, Maria will use all the power at her disposal to stop the fighting, whether that means conjuring giant dragons or sending her succubus familiar out to mesmerize the warring generals with her charms. But what do the villagers think of her "help"? And what will happen if Heaven notices her interference into human affairs? This story has a funny touch with a little history thrown in!

In the future, Earth has become so polluted that humanity is forced to live in enclosed shelters. In Japan, the shelters are divided between the "inside", which caters to the country's lucrative anime industry, and the "outside", where most people work to support the people working on the "inside". S-zawa is one such "outside" worker whose job involves sending messages into space. One day, he's approached by the ailing embodiment of Earth to send a message before she collapses. Shortly after the message is sent, other girls similar to Earth start showing up at S-zawa's workplace in an effort to help Earth, but he has a thing or two to learn about what the planets and their moons are really like.
