Best friends Tokio and Azuma do everything together, even if most of the time it feels like Tokio is just stumbling along in Azuma’s cooler, more talented footsteps. But when they’re attacked one night by a superhuman mutant called a choujin, Tokio finally has a chance to shine—by turning into a choujin himself!

Tokio and his new choujin buddy Ely are now training to become superpowered protectors of the prefecture. But in addition to having to cram their noggins full of choujin rules and regulations, they have to deal with fledgling abilities that won’t always do what they’re supposed to…in ways both embarrassing and dangerous!
