You Were Told to Do Research, Not Drive the Land of Light Insane

After transmigrating to the Land of Light, I became Stony Ultraman, the younger brother of Mother of Ultra, a good-for-nothing researcher who loves inventing things.

Luckily, I activated the [Happy Inventor System]. As long as my inventions make their users “happy,” I can earn rewards and grow stronger!

But the System has one awful catch: every invention comes with a random “comical” side effect!

When Captain Zoffy leads the Space Garrison in grinding the monster army into the ground while dancing to “The Most Dazzling Ethnic Style”;

When Ace unleashes the Ultimate Guillotine, but has to shout the chuuni line “In the name of the moon, I'll punish you!”;

When my brother-in-law, Father of Ultra, watches the Ultra Brothers collectively dance in an excruciatingly embarrassing moment, broadcast live across the universe...

I, Stony, became the shared nightmare of every monster and Ultraman in the universe!

Monsters: “We can't beat him, and we don't even want to try. It's too humiliating for monsters!”

Ultra Brothers: “Stony, please! Can you make the side effects normal this time?!”
