Transmigrated into Ultraman Taiga, I Eventually Became Reiga

On the first day Lin Ye fell into the world of Taiga, the System gave him a Light Core that was on the verge of going out. Before the third day was over, he was already standing before a monster, transformed into a Giant of Light of his own. Taiga taught him how to throw a punch, Fuuma taught him how to catch up with those he couldn't afford to leave behind, and Titus taught him how to stand his ground. Later, the light of eleven New Generation warriors came into his hands one after another, and Ginga was finally more than just a name in his memories. But on the other side of the rift, someone else was waiting for those eleven beams of light. They wanted him to make a decision on behalf of everyone. Lin Ye dismissed the compulsory options listed by the System, turned to his companions, and asked, "This time, who wants to come with me?"
