Lin Cheng finds himself stranded in the magical, chaotic world of Fairy Tail, a realm far more dangerous than the anime suggested. Without initial powers, he struggles to survive until the activation of the Strongest Puppet System changes his destiny. This unique cheat allows him to summon loyal puppets drawn from characters across the multiverse, fueled by the emotions of those around him.

After a tense initial summoning, Lin Cheng acquires a critical hit: Petelgeuse Romanee-Conti and an army of Sloth Cultists from another dimension. Now possessing a fanatical, madness-inducing force at his command, Lin Cheng must navigate the explosive conflicts of Fiore. While appearing to be an ordinary bystander, he quietly pulls the strings from the shadows, manipulating events and powerful mages alike.

As explosions rock the desert night, the true mastermind behind the coming chaos prepares to rewrite the story of Fairy Tail from the background.
