In the World of Ultraman: From the Start, I Got the Geed Riser

(No heroine + starts in the Geed world + not an invincible protagonist + moderately satisfying + leans toward the Ultraman side + human side + System is a pain + comedy)

Lin Ye died suddenly at home in his previous life. Unwilling to accept his fate, he transmigrated to the Geed world and obtained the Sublimator System. He thought he could beat the crap out of Belial and kick the Land of Light to pieces, but the System told him he didn't have any powerful items. So he forced the System to upgrade, only to discover that the current timeline was the Crisis of the Spark, and Belial was about to detonate the Super Dimensional Bomb.

Lin Ye couldn't just sit around doing nothing, so he opened his beginner's gift pack and became Noah from the start, leaving everyone stunned. But his System was such a pain.

And so, his legend began to spread across the universe.

Noah: This little punk even wants me to give him a cheat.

Belial: Lin Ye, you bastard! He turned into Noah and hit me with a Noah Hellfire!

Orb: Lin Ye, save me!

No way. First, I need to calm down and give each of you a big slap.
