You awaken within the world of Katekyo Hitman Reborn. The stage spans both Japan and Italy: Namimori City with its quiet suburbs, Tsuna’s house, Namimori Middle School, the shopping districts, and the hospital—all contrasted by Italy’s mafia heartlands, including Vongola mansions, fortresses, and underground battlefields.

The timeline strictly follows the canon of the anime and manga, from the introduction of Tsunayoshi Sawada to the final arc—unless you intervene directly, in which case events will adapt around your choices and actions, ensuring your presence shapes the story without breaking its flow.
