Ultraman: The Second Lionheart Emperor

[Four or five female leads + multiple Ultraman storylines + character assassination + irreverent protagonist + L77 Star destroyed, protagonist inherits his father’s power] Long Xiao was killed when a truck of good fortune hit him, and accidentally transmigrated to the Ultraman world. Unlike everyone else, he ended up in the D60 System. From the start, he was Leo’s older brother, and studied the Cosmic Beast Fist on D60. But before he could master it, the Magma Seijin invaded. By the time he returned to L77 Star, the Magma Seijin had destroyed his home, and Leo and Astra were nowhere to be found. In the end, Long Xiao said farewell to everyone on D60 and headed to Earth with Ling Lan to find Leo. By chance, he came across the Magma Seijin leading the Twin Monsters in ganging up on Leo and Seven. After rescuing Dan Moroboshi, the protagonist turned down an offer to join MAC and instead dumped Leo on him… But after leaving Earth, the protagonist encountered transmigrators from another Earth. Their world also had Ultraman, but the story had only aired as far as Tiga. By a twist of fate, the Ultraman fanatics on this Earth gained a strange power that let them leave their Earth’s dimension and seek out the Land of Light. But Father of Ultra turned them away outright, calling them people of darkness. Enraged, they began altering the story, strengthening powerful bosses or kidnapping them, inflicting tremendous damage on the Ultra Warriors. By another twist of fate, Long Xiao gained the power of his father, the Lionheart Emperor, and became the second-generation Lionheart Emperor. But what followed was Long Xiao turning into a firefighter, rushing everywhere to put out fires and working himself to the bone.
