A solitary dragon named Oragon receives an unexpected summons: the Strike World faces total destruction, and only legendary monsters can prevent catastrophe. Across a sprawling anthology of interconnected tales, Oragon encounters an unlikely cast of powerhouses recruited to stand against the looming threat. Among them walks Lucifer, a fallen angel bearing the weight of her past, and Arthur, a knight whose legendary skill masks deeper scars. Solomon, a mage princess, commands forces most would never dare approach. Each character arrives with their own motivations, secrets, and reasons for answering this desperate call. What unfolds is a series of action-packed episodes that balance genuine stakes with comedic relief, letting these monsters develop beyond their game origins into actual characters with conflicting desires and surprising depth. The omnibus structure means each arc brings fresh perspectives on the same world and overlapping conflicts, creating a mosaic where battles matter and humor punctures tension at just the right moments. This isn't about saving the world through heroic speeches. It's about impossible odds, strange alliances, and whether monsters destined to oppose each other can find common ground.
