JoJo's Bizarre Adventure: Divine Oracle

When the pocket watch's curse awakens in his bloodline, the boy Feng Xinzi is forced into a gamble to overturn his fate.

Bearing his family's century-old curse of “September 1,” he follows the brand on the back of his hand in search of mysterious pocket-watch fragments said to grant wishes, only to be swept into a whirlpool of competing forces. A world of substitutes, farewells in life and death that cannot be changed, and a dramatic turn of events forcibly add vivid color to Feng Xinzi's otherwise ordinary high school life...

(Some parts of this story draw on the author's own high school experiences. I hope it gives you something to think about.)
