James Porter was an average, overweight nerd with a passion for video games and fantasy novels, until a magical bus, "Bus-kun," hits him, transporting him to a fantasy world filled with magic, monsters, and adventure. Reincarnated as a lean, muscular, and handsome version of himself, James discovers he has an innate talent for fire and lightning magic, though his chaotic use of spells often causes more problems than it solves. In this new world, James is tasked with preventing an ancient evil god from escaping the underworld and bringing destruction to the land. Along the way, he forms a ragtag party including a snarky but brilliant witch with a cat familiar named Cosmo; Leonidas, a stoic lion beastkin knight with a holy shovel named Carol Anne; and Katherine, a sharp-tongued explosives obsessed elf. The group embarks on wild quests, from battling monsters and solving murder mysteries to navigating a bizarre, physics-defying Wonderland-like realm. As they face increasingly dangerous enemies, James learns to harness his overpowered abilities, befriending quirky allies like Goop, a sentient green slime, and Bob, a wisecracking skeleton. Together, they uncover the dark cult trying to release the god and find themselves in the middle of tournaments, royal intrigues, and epic dungeon crawls. With a blend of humor, action, and heart, this Dungeons & Dragons-inspired adventure follows James as he fumbles his way toward heroism, discovering that saving the world might just be the adventure of a lifetime.
