I'm in Tiga, and I'm the True God, Kyrieloid

[Contrasting personalities + lighthearted comedy + overpowered showboating + battles across multiple worlds + decisive and ruthless + no saintly do-gooder + one or more heroines]

After transmigrating into the world of Ultraman Tiga, Lin Ran discovers he has become a Kyrieloid, about to be blasted to bits by Tiga’s Zeperion Ray! Looking at the Giant of Light before him, its warning light flashing red as it forms a cross with its arms, Lin Ran panics. At the brink of life and death, the “Myriad Worlds Show-Off System” activates! As long as he shows off, slaps faces, and racks up Shock Points, he can evolve without limit.

Lin Ran casually slaps Tiga’s finishing beam away, kicks him into the ruins, then stands in midair and proclaims to the world, “I am the true god who protects Earth!” All of humanity is stunned, Captain Megumi is left speechless, and GUTS spends the night revising its battle plans.

He thought he could settle down as a revered “Flame Demon God” and maybe enjoy some romance, but then dimensional rifts suddenly open. Zero, Belial, Hyper Zetton, and all sorts of otherworldly beings, even Godzilla, crash into the main world to claim territory!

“Hey, the guy with two flying blades on his head! Put those blades down! This is Earth, not the backyard of your Land of Light!”

Facing a sky full of gods and demons, Lin Ran cracks his knuckles as a raging sea of flames in his Ultimate Hellfire form appears behind him. Everyone, are you ready for a god to beat you senseless?
