DESCRIPTION
Tokio Kurohara, a second-year high school student, enjoys slacking in class. Despite his demeanor in school, he joins forces with his childhood buddy Azuma Higashi to fight the injustice that is brewing in their village. In contrast to Tokio, Azuma is physically capable and rarely fights the thugs they confront on a regular basis.
Even Azuma, though, will not choose certain fights. Tokio and Azuma will go to any length to escape Choujins, supernatural beings with abilities far beyond those of normal mortals. When a gangster who had previously been defeated comes to pursue revenge, the two are forced to fight. In order to escape their attacker, the pair injects themselves with a medication that transforms them into Choujins.
