Simultaneous Transmigration: Unchanged Heart, Sleep and Scheme

Ma Kai transmigrates into the world of *Chūka Ichiban!*, landing as a lowly apprentice in the Dark Cooking Society. On the verge of becoming a slave, he discovers after a single night's sleep that he is not alone—he has undergone simultaneous transmigration across multiple worlds. His incarnations share abilities, memories, and even stack physical traits. In the *Tomie* universe, as Tomie's twin brother, he gains incredible regenerative powers—along with the troublesome side effect that anyone of the opposite sex who spends too long near him becomes obsessed with bearing his children. After one night, his strength soars, yet his core resolve remains unchanged. He faces off against Xiang En, Zhilin, Lady Lei Hua, and even Fei—whose "National Glory Noodles" may be peerless, but Ma Kai dismisses all as mere pretenders. In the *Claymore* world, he is the first male warrior, the supposedly useless No. 47—yet his juniors keep forming parties to hunt him down, and his cellar is running out of space. In the *Digimon* universe, Mimi and LadyDevimon both fall for him. Then come the *Slayers* and *One Piece* realms—and after *Chūka Ichiban!* concludes, so does *Hunter × Hunter*: humanity's fear of the Dark Continent stems from insufficient firepower, and the New Dawn Agency's Mobile Suit Research Institute will become the beacon illuminating that abyss. His kill list includes Hisoka, the Phantom Troupe, and Illumi—and he tells Kurapika that chains are a dead end, urging him to manifest a Striker Gundam instead. After *Sailor Moon* ends, he saves the world and figures a harem is only fair. After *Gundam Seed*, he vows to tear mobile suits apart with his bare hands. With the *One Piece* world concluded, the ongoing arc now shifts to a Hong Kong crime drama universe.
