줄거리

Sanshima Koudai is a high school delinquent who frequently gets into fights. His childhood friend, Hikaru, is the only one who can keep him in check. One day, at the Sanshima produce store, Koudai and Hikaru eat a mysterious package, believing it to be a rare fruit. It turns out to be a "Taisai," one of three in the world, which grants eternal youth to those who consume all of them. Eating just one bestows a lifespan of thousands of years, marked by a red line on the forearm. A Chinese "Sennin" arrives, explaining the Taisai's significance and the dangers it brings, as many powerful individuals seek eternal youth and will stop at nothing to acquire the Taisai.
