Galactic Pirates

Katsu Kaizou is a very gullible, 17-year-old high school student and a believer in science fiction, aliens, ghosts, UFOs, conspiracies, etc. He thinks that everything going on around him is the result of some sort of alien plot to take over the world. Each story is pretty much self-contained and is completely bizarre. Kaizou joins the school's science club, makes new friends, and ends up coming in contact with all sorts of strange things like log people, deadly sushi, pee-blades, scary infections, robot invasions, ghosts, living dolls, and more!

In the midst of a global crisis as the supercomputer that manages the earth's energy has seized control of all global functions and reduced humanity to the level of hunters and gatherers, a young smuggler and his robot sidekick rescue three high-class girls stranded on their way home from their school on the Moon and then a mysterious alien and his translation cat. Can this motley crew uncover the mystery of the supercomputer's actions and save humanity?

Yuu and Saya are two of the top Cosmic Hunters in the galaxy, and Yuu is enjoying a bit of fame after his most recent adventure. The two are on a date when they are interrupted from a distress signal from their "ally", the feline pervert Nyan. In the meantime, the space pirate Belga begins attacking space freighters in an attempt to lure out Yuu, so she can take him to bed with her. Of course, when he spurns her, she decides that if she can't have him, then no one can.

The story revolves around Kakazu Kio, an ordinary high school freshman living in Okinawa. A girl with cat ears appears before him during a memorial service for one of his family ancestors. The girl calls herself Eris and claims she is an alien. Before long, fanatical alien worshipers and a mysterious government agency are in hot pursuit of Eris, but Kio's childhood friend Manami—who wants to follow in her father's footsteps in the CIA—captures Eris. Kio finds himself having to protect Eris from everyone.
