Ultraman: I, a Blue, Cautiously Became the Strongest

After transmigrating to the Ultraman world, Sairen became Zero's older brother. Although his Blue Tribe genes were more prominent, his combat talent was every bit as impressive as Zero's.

But Sairen couldn't be bothered to fight himself, so he chose to lie low in the Land of Light.

Fortunately, he obtained an Ultraman Simulator when he transmigrated, allowing him to grow stronger without even leaving home.

In his first simulation, he gained a rainbow talent: the stronger his opponents, the stronger he became. Traveling the universe alongside Tregear, he left behind a legend as the invincible Blue Tribe member.

In his second simulation, he gained a golden talent: a scientific research maniac. The cheats Sairen created boosted the overall strength of the Land of Light and even cured Father of Ultra's back injury. They then overwhelmed and killed Belial when he broke into the Land of Light.

When a simulation ended, Sairen could keep some of its gains in the real world.

By lying low, Sairen eventually became the strongest fighter in the Land of Light.

One day, when Belial broke into the Land of Light, the sky practically fell.

Belial: Wait, weren't the Blue Tribe supposed to be this weak?

Sairen: First, the Blue Tribe can get stronger too. Second, I only chose to become a Blue Tribe member after I ran out of opponents to fight!
