Kengan: This Scientist Is Overpowered Yet Recklessly Self-Destructive

[A swaggering genius, multiple heroines, canon couples remain intact. Enjoy! Character inspirations: Vegeta, Agul, Gilgamesh.] A top scientist with technology far ahead of its time accidentally transmigrates to the world of Kengan Ashura. A genius who treats rules as meaningless and has almost no common sense decides to give this world a little taste of technological shock. He enters the Kengan Annihilation Tournament, not for victory or defeat, nor for money or fame. To him, this arena filled with sweat and murderous intent is simply the perfect outdoor laboratory. This is the story of a top scientist wreaking havoc on the fighters of the Kengan world with a heap of absurd inventions, while turning the entire Kengan Association upside down along the way. “Don’t mess with that mad inventor. He really will do whatever he wants with your body and your fragile feelings, just to test some ridiculous gadget.”
