"Second year student of Torauma High School, Katsu Kaizou is a cyborg. Attacked by mysterious people and left close to death with severe injuries, he was turned into a cyborg by genius scientist Saien Suzu which saved his life. She brought along with her the underling Tsubouchi Chitan along with whom Kaizou continues his fight.

Or at least, this is what he imagines..."

Katte ni Kaizou was one of the earlier works of the incredibly under-appreciated manga artist Koji Kumeta who is most known for his "Sayonara Zetsubou Sensei". It follows the hijinks of the former genius Katsu Kaizou, who believes in various conspiracy theories, aliens, etc. due to an injury he sustained from getting pushed off of a jungle gym, and the other members of the science club whom, by accidentally dropping a anatomy model on his head out of the second story of the school building, caused him to believe that he was reborn as a cyborg!
