Kazehaya Kamito has been summoned to the girl's school Areishia Spirit Academy, which teaches noble young ladies how to make contracts with powerful spirits. On his way, he has the misfortune of catching sight of one of these lady spirit contractors bathing. She is Clair Rouge, and she is contracted to a spirit named Scarlet, though she has her sights set on a more powerful spirit. Kamito convinces her to lead him to the school, but she stops on the way to make a contract with this powerful spirit. When Kamito ends up 'stealing' the powerful spirit, it is revealed that he is actually an unheard-of male spirit contractor! What could be the origin of his power? Now Clair is determined that he's going to have to support her, since she believes that the spirit he now has power over what should rightly be hers... [tethysdust]

Now Masaki has to juggle two of the most prominent members of the community, the goddess of the land and the member of the Tagami family, and prevent it from blowing up in his face.

Oogami is a detective by day and exorcist by night, solving cases and hunting spirits together with his ghostly assistant Kazari. One day, a mysterious package with horrifying contents arrives in Oogami's mail, the only clue to its sender being the name of a remote village: Shirasunamura.

Note: The Japanese-character title keeps cutting off in the field below after the last "shi" or "death" for some reason. The title should be: 死にたくなるしょうもない日々が死にたくなるくらいしょうもなくて死ぬほど死にたくない日々.

It's an age where aliens, monsters and other dangers threaten the Earth, and various heroes have risen to protect it.

Billy Bat is a comic-in-a-comic and the real protagonist is a Japanese-American artist named Kevin Yamagata who draws Billy Bat for "Marble Comics".
Shortly after they transition to the artist in his studio with his assistant, two actual detectives, who look like Laurel and Hardy in Dick Tracy era suits and trench coats, knock on the door and appropriate Kevin's room for the purpose of conducting surveillance on a room in an adjacent building. One of the detectives, the skinny “Laurel”, sees Kevin's work and it turns out he's a Billy Bat fan. The other chubby "Hardy" detective picks up a page and says that the characters look familiar and accuses Kevin of translating an old "Jap" comic.
As Hardy remembers the comic he thinks Kevin is ripping off, we make another Urasawaesque time jump to 1949 Tokyo.

Note: Won the Max und Moritz Prize for "Best international Comic" in 2014.
