High-school student Dong-Jin 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, Dong-Jin 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? (Source: WEBTOON, edited)
