Yu Yu Hakusho: Ghost Files

A teen delinquent becomes a spirit‑world bounty hunter, battling demons to earn his second chance.

Yusuke Urameshi is a teenage street punk who spends his days brawling and skipping school, until a single act of reckless heroism forces the afterlife to intervene. He throws himself in front of a truck to save a child, an altruistic move so out of character that the Spirit World can’t simply move him on. Koenma, the infant ruler of the realm, offers Yusuke a loophole: become a Spirit Detective and earn his second chance by hunting down supernatural threats that seep into the human world. Guided by Botan, the cheerful ferrywoman of souls, Yusuke is thrust into a series of increasingly dangerous missions that test his newfound resolve and raw power. As the stakes rise, Yusuke assembles a ragtag squad: the hot‑headed but loyal rival Kuwabara, the flame‑wielding demon Hiei, and the fox‑spirit botanist Kurama, each harboring dark pasts and hidden strengths. Together they train, clash with mythic foes, and uncover conspiracies that could unravel humanity itself. The series blends high‑octane martial arts, mythic lore, and sharp humor, charting Yusuke’s evolution from delinquent to guardian of the living and the dead.

A 90s shounen battle series where a teenage delinquent becomes a spirit detective fighting demons in escalating tournaments. Expect lots of stylized supernatural violence with blood and some grotesque imagery, plus heavier emotional themes like child trauma and death that deepen as the series progresses.
