**Title:** *Katekyo Hitman Reborn!* (en)

**Genre:** Action, Comedy, Supernatural, Mafia, Shonen

**Atmosphere:** A masterful, volatile fusion of slapstick schoolyard comedy and high-stakes mafia warfare. The story begins as a whimsical, chaotic farce before seamlessly evolving into an intense, emotionally driven saga of loyalty, legacy, and explosive power.

**Synopsis:**

But as Tsuna collects a loyal, misfit crew (known as the Vongola Guardians), his world expands beyond survival. The true story emerges: a race to master ancient Vongola artifacts, confront the family’s bloody history, and dismantle a shadowy curse that threatens the entire Mafia underworld. What began as a joke becomes a question of destiny—can a boy who can’t even say “no” become the leader of the world’s most feared crime syndicate?
