Ultraman: Light as the Link, Choking Generation After Generation

An ordinary young man, Lin Yu, was rewatching Tiga Ultraman when he suddenly fainted.

When he woke up, he found that he had transmigrated into the world of Tiga and become an ordinary employee at the TPC Far East Headquarters.

At first, Lin Yu planned to resign, spend all his savings, and run back to China to stay far away from the plot.

But he was guided by a mysterious summoning to an ancient supercivilization ruin, where he saw the illusory form of the legendary Ultraman Noa.

Noa told him that he was the chosen inheritor and would gain the power of Noa's Light, becoming a new warrior of light—Ultraman Nexus.

Run? What was there left to run from now? Gatanozoa, take this: Noa Inferno!

...

(With borrowed and fused new forms, and a partial addition of the Trigger world:

Dark Tiga + Tiga = Truth Tiga; the Light of Jinguji and Nexus = Nexus Swordmaster Form)
