Mechas Can't Defeat Monsters? I Will Directly Transform into Diga

Shen Ci was accidentally reborn on a planet called Blue Star and became the summoner of Ultraman Tiga. Blue Star is being invaded by monsters. Countries in Blue Star rely on advanced mecha technology to fight against the monsters. But as time went by, more and more powerful monsters appeared in the monster wormholes. The human mechas were defeated step by step, and finally they pinned their hopes on the giant of light, Ultraman Tiga. "I am both light and human." Shen Ci: "The bond alone has tied a knot in my body, so I will protect Blue Star." As the sound of light sounded, Shen Ci transformed into Ultraman Tiga in the beam of light and walked into the darkness alone. (In addition to Tiga, I will also write about some other Ultraman. The introduction is insufficient, so please enter the text.)
