He was reincarnated into a stereotypical shoujo manga with magic and fantastical creatures- not as any of the main cast, but the villain's butler, a kindhearted but loyal to a fault beastkin who fought to his death to let his abusive master escape- a mere narrative tool to make the villain seem even crueler. Unlike the original, however, he was not kind, nor was he loyal. He is not above killing, stealing, and lying- and he did not care if he was despised. To avoid a meaningless, pitiful death, he would even scheme his way to escape fate. Upon meeting the young villain, however, there was a change of plans. In this second life of his, he'll bet everything on the villain, and fulfill what the original couldn't- he will help the villain find the happiness that was so cruelly taken from him- no matter what it takes.

(Chapters 1-17 Rewritten) I died prematurely in the least cliché way possible... Vaporized as a result of a powerful and fantastic nuclear explosion! How cool, right? But that was only the prologue of my adventure... I was reincarnated in the world of My Hero Academia as the little brother of the protagonist with a wonderful and terrifying quirk of intelligence. With great power comes great responsibility... Hah! Boring! I will use the power of my twisted imagination to have a lot of fun in this world by unleashing chaos around me while I enjoy the show eating popcorn. Sometimes a child just wants to see the world burn... A fantastic giant robot! A really cool lightsaber! Robotic tentacles! Anything my twisted mind can imagine! I'll build it! And I plan to have a lot of fun in the process! So I became the youngest S-Rank Villain in the world, created an evil organization for my amusement, and as if that wasn't enough... I completely altered the plot for my personal benefit. And the best of all! No one suspects that Izuku Midoriya's innocent and charismatic little brother is really the mastermind behind all this chaos! "I am Child Emperor! And this world will become my playground!" I exclaimed happily, raising my fists in the air in front of a terrified crowd of heroes and villains. "HAIL HYDRA!" I exclaimed defiantly from atop a gigantic combat robot as a crooked smile spread across my face. Something tells me there will be no school tomorrow... Hehe.
