Part of "ergo" magazine which features manga all written by Konohara Narise.

The Emperor of Evil, Ichidaiji Hiiro, and the Warrior of Justice, Hiroin Manami, fight each other every day, at any time, at any place, even at school! Aside from the usual conflict, both live their high-school life at Super Electric High School (超電寺学園), full of fun and slightly erotic moments. (Source: Amazon, translated and edited)
