Dark humor and quirky horror unite in this tale of clashing heroes and monsters from the creator of Tokyo Ghoul and Tokyo Ghoul: re! 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! Azuma has always felt driven to help others, and his need to become a choujin is just an extension of that desire. But when he finally turns, it's not the victory he dreamed of. Now, rather than fighting side by side with Tokio, he's trying to kill him! Forget repairing their friendship--can Tokio escape their reunion with his life?
