Reincarnated into a villain is not good. Especially when the world you get reincarnated into is where the main character runs around the world as a murder hobo and waifu hunter. It gets even worse. He will steal my fiancee, and my family will be massacred to the last soul.

Lucky for me, the one who reincarnates me here is kind enough to give me a cheat. With my [System Copying System], I will make sure to steal his system and kill that shit for good. Huh? What do you mean he is not the only main character?! Huh? Spin off? Sequel?! What?!
