Turn defeated monsters into allies! A growth-driven adventure of deepening bonds to challenge the Great Demon King!
The kind-hearted hero Guest possesses the unique ability to make defeated monsters their allies. Their first traveling companion is Punimaru, a crybaby slime. Throughout the journey, they connect with various monsters, deepening their bonds by compensating for each other's flaws. Iris, a beautiful knight, and Lionel, a handsome knight, accompany them as overseers. Moved by the sight of Guest and the monsters trusting each other and growing through their struggles, they eventually become true comrades. Soon, the threat of the Great Demon King, who seeks to consume the world, draws near. When those who have connected their hearts gather to form one massive "bond," the curtain rises on a world-shaking adventure!

◆ Real Name: Great Demon King Garzard - The Thunder King of the End [Spawn Condition] Appears after Volga is defeated. ◆ Character Setting: The absolute ruler of the demon race who seeks to plunge the world into darkness and chaos. He was sealed in ancient ruins but has been resurrected in the present day alongside the world's distortions. Possessing overwhelming magical power and cold intelligence, he views even his subordinate monsters as nothing more than "disposable pawns." ◆ Personality: Arrogant and ruthlessly cruel. He holds an extreme social Darwinist philosophy that "the weak are meant to be trampled by the strong." Consequently, he views Guest and his companions, who fight through bonds and compensating for weaknesses, as a "pathetic huddle of the weak" and looks down on them from the bottom of his heart. ◆ Abilities & Combat Style [Disaster Bolt]: Pale lightning released from his jet-black sword can pierce mountains in a single strike and violently erodes the magic of those it touches. [Evil Guardian]: The giant single eye on his greatshield glows eerily, deploying an absolute defense wall that reflects all physical and magical attacks. [Curse of Servitude]: A terrifying technique that pollutes the minds of weakened monsters, stripping them of their ego and turning them into berserk puppets. ◆ Connection with Guest: The one who previously used force to subjugate the human-hating dragon Volga and attempted to break his spirit. Garzard, who sees monsters only as "tools," versus Guest, who treats them as "irreplaceable comrades." Their conflict is the very embodiment of the theme "Dominion and Terror" vs. "Bonds and Trust."
