Katte ni Kaizou - Kumeta, Kouji

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!
Included one-shot:
Volume 13: Yuuryou Bukken Chuukai Shimasu (A Brooding, Gloomy Property)

Katte ni Kaizou was published in Spanish as Katteni Kaizo by Ivrea from June 30, 2003 to July 16, 2010.
