Kai, a 17-year-old who dreams of becoming the world's strongest villain, keeps failing at the one thing he wants most... because every time he tries to be evil, he accidentally saves people instead. Marked by a dangerous seal and pulled between two destinies, Kai teams up with Aria-the responsible mage who keeps him alive-and Lyra-the chaotic troublemaker who encourages the bad ideas. Together, they face traitors, monsters, and a legendary enemy who wants Kai to embrace the darkness inside him. But Kai discovers something shocking: He's not destined to be a villain or a hero. He gets to choose. Action, comedy, chaos, and slow-burn romance collide as Kai tries to survive magic school, runaway missions, world-ending threats... and his own dumb luck. A villain story that refuses to stay villainous.

"When a street magician gets dragged into a deadly realm of living cards, he must fight monsters, unlock psychic powers, and face the Joker-the strongest creature ever created." Si Mage Ryan, isang simpleng magician na pang-baryuhan at pang-street show lang, ay biglang nahulog sa isang dimensyong tinatawag na Deck Realm-isang napakalaking dungeon na puno ng halimaw na kumakatawan sa bawat card sa card deck. Dito niya makakalaban ang: ♣ Beast-type creatures ♦ Crystal assassins ♥ Emotional spirits ♠ Shadow killers ...at ang pinaka-nakakatakot sa lahat: ang Joker, ang pinakamalakas na nilalang sa buong laro. Habang lumalalim ang laban, unti-unting nagigising kay Ryan ang mga kapangyarihang hindi niya alam na taglay niya- psychic intuition, telekinesis, teleportation, at iba pang abilidad na nagmumula sa mga halimaw na kanyang napagtatagumpayan. Ngunit sa likod ng bawat panalo, may nakatagong hiwaga- Bakit siya ang napili? Ano ang tunay na ibig sabihin ng pagiging Magician ang 52 monsters at dalawang Jokers ng Deck Realm, hindi siya makakabalik sa tunay na mundo. At kung manalo siya... baka hindi na siya ang Ryan na dating kilala niya.
