MHA: My Little Brother is an S-Rank Villain For Fun! My Chaos Academia

So I'm reincarnated in My Hero Academia as the protagonist's little brother with a terrifying intelligence quirk, there's just one small snag.

I became the youngest S-rank villain in the world, I completely destroyed the plot and I control an evil organization called Hydra just for fun.

With my knowledge, I plan to have fun in this world, after all, in this superhuman society, if you can dream it, you can do it. In my case, I can build it!

A lightsaber, an evil Furby, robotic tentacles, many inventions, and many minions.

Heroes and villains are just pawns in a grand and elaborate game. My game!

“Prepare for trouble and you had better be afraid! Because I am Child Emperor and this world will become my playground!”
