High-school student Dongjin Kim seems like a typical moody teenager, but underneath it all, he’s a powerful psychic “villain” who aims to destroy humanity. But there’s a catch - every time he uses his powers to kill, he is thrown back in time. Trapped in this time loop, Dongjin tries to narrow down the culprit by doing the one thing he knows: killing those around him. Will he be able to escape from the time loop and achieve his goal as a villain?
