HIKARI-MAN manga omnibus volume 2 collects volumes 3-4 and features story and art by Hideo Yamamoto.

In his guise as electrified superhero Hikari-Man, young high school otaku Shirochi Hikari has taken care of most of his tormenters--but then the super-yoked upperclassman Daiya shows up at his house looking for revenge! Even if Hikari-Man can defeat him, does that make him a hero, or just a high-voltage bully in his own right?!
