The following is a version that polishes the English copy you provide, enhancing emotional expression, character portrayal and story tension: --- Seventeen years ago, the world first bore witness to the appearance of immortals on the war-torn battlefields of Africa. Since then, a mysterious and rare new form of life—neither fully human nor entirely other—began to emerge among us. These beings came to be known as "Ajin," or demi-humans. Just days before the summer vacation begins, a quiet Japanese high school student loses his life in what seems like a simple traffic accident on his way home from school. But death does not claim him for long. He returns—unscathed, untouched by time. And with that return comes a terrifying revelation: his existence is now a bounty-marked secret, hunted by those who fear what he has become. Thus begins his desperate flight—not just from the law, not just from scientists and soldiers—but from all of humanity itself. --- If you have a Chinese version or other language version, or if you want to further adjust your tone according to a specific style (such as suspense, passion, and philosophical direction), you can also tell me that I will tailor it for you.
