## Summary

Chapter 1 introduces the primary characters: Mamama, the demon lord, and Corleo, the hero. These two monikers possess a unique bond, as they are reincarnated each time one of them dies, identifiable by distinctive markings on their hands. Their world currently enjoys a period of newfound peace, brought about by the sacrifice of the previous hero, Halohalo, who gave his life to establish harmony between humans and demons. This coexistence has become the norm for both species.

However, Corleo, the current hero, struggles to find his purpose in this era of tranquility. He conceals his confusion but grapples with understanding his role during peaceful times. Mamama, the demon lord, fails to grasp his inner turmoil, lacking empathy for his perspective.

Corleo's life takes an unexpected turn when a hero from another world, Evan All Green, appears in their realm. Evan's reluctance to accept a world where humans and demons live together leads to a tense encounter with Mamama, given her marked hand. Evan warns of the potential arrival of his world's demon lord, instigating fear among the demons. They worry that the presence of two heroes in their world might lead to its destruction, so they temporarily imprison Evan. In an effort to prevent harm, Evan proposes that if they allow him to defeat his world's demon lord, he will willingly sacrifice himself.

Inspired by Evan's genuine heroism, Corleo visits Evan in his cell. Evan reveals his unique power, "sigil sorcery," which allows him to perform magic, a power absent in Corleo's world. Using sigil sorcery, Evan transports them to a forested area and suggests they spar while having a conversation. Despite Corleo's lack of training, Evan praises his skill. When Corleo questions Evan about the meaning of being a hero, Evan concludes their fight without providing a direct answer, urging Corleo to find his own path.

Upon returning, Corleo intervenes to stop a group of children from bullying another child. Mamama scolds him for potentially disrupting the peace. Suddenly, Evan transports Corleo to a dark void, warning of the impending arrival of his world's demon lord. Demon Lord End, a grotesque amalgamation of various faces and limbs, emerges, terrifying Corleo. Although Evan easily subdues the demon lord, he reveals his true intentions: to take Corleo's place as the hero of this world, as his own world has become uninhabitable.

As Evan questions Corleo about the essence of heroism, the demon lord from Evan's world taps into Mamama's power and regenerates behind Corleo. In a final act of bravery, Corleo sacrifices himself by throwing his body between Evan and the demon lord, realizing that being a hero means confronting their formidable adversary to protect.

Corleo awakens with Mamama and Evan at his side. Touched by Corleo's selfless sacrifice, Evan offers his life force to the boy, acknowledging his own past indiscriminate killing and believing himself unfit to be a hero. Before passing on, Evan hears the voices of his former comrades calling out to him, and he asks if he can join them.

The hero from another world disappears, leaving behind nothing except his clothes and sword; Corleo rising in his wake.
