Kaneki Ken, a ghoul in Tokyo, is a monster that devours human beings in the chaotic and noisy modern city of Tokyo. People call it species. Their appearance is almost the same as that of human beings, but they only feed on human beings and are natural enemies of human beings. On that day, Kaneki Ken, an ordinary student of Shanghai University, met a mysterious woman, Miss Dai Lishi (actually a species) and was involved in an elaborate accident. From then on, he was transformed into a half-human, half-species, and once felt lonely and helpless, but he was taken in by an antique (animated version translated as "anding district") coffee shop, but the good times did not last long. The "bronze tree" organization quickly found him and was taken away and tortured. Finally, he understood that "weakness is evil" and decided to become stronger and go on. ?
