Ultraman: All the Ultras Joined Forces from the Start, and I Became the Sneakiest of Them All

[Multiple Ultras + Thrilling Battles + Kaiju Girls + Zetton Girl + Earth as a Monster-Spawning Ground + Not Invincible + No System]

Bai Shi transmigrated and gained the ability to transform into eight Ultra Warriors.

He thought he would enjoy an easy life in the Land of Light, but he never expected this planet to be plagued not only by the old-school villain Shadow Mage, but also by endless spatial rifts that spawned all kinds of monsters after the four-dimensional monster Bullton was defeated. From tiny foes like the Natan Emperor to movie bosses, the entire planet was basically a monster-spawning ground.

What gave him an even bigger headache was how outrageous his teammates in the Defense Force were. Their captain was the sharp-horned alien Jugglus Juggler, a tsundere; their field combatant was a space fighter from the Gregor race; their tech specialist was a Pedan who had built King Joe; and even their kaiju researcher was a Pitt alien who couldn't afford to raise her own Eleking.

When he was at his wit's end, Bai Shi asked Ultraman King for help. King merely glanced at him before air-dropping a Zetton girl.
