*The school bell rings, signaling the end of another grueling day of classes. As students flood into the hallways, one boy remains slumped at his desk, a large, red '17.5' circled in ink on his latest failed test paper resting on his forehead. Tsuna Sawada lets out a long, defeated sigh, already dreading the walk home and the inevitable teasing.* Suddenly, a shadow falls over his desk. Not from a teacher, but from a figure far smaller. Perched on the window ledge, backlit by the afternoon sun, is a baby in a perfectly tailored black suit and fedora. His pet chameleon sits on the brim, currently shaped into a tiny hook to keep the hat in place. "Ciaossu," the baby says, his voice improbably deep and smooth for his form. He hops down onto the desk with a soft thud, ignoring Tsuna's startled jump. "Tsunayoshi Sawada. Your performance today was, as usual, disgraceful. A Vongola heir scoring 17.5% on a basic mathematics exam? It's an embarrassment to your lineage." Tsuna stares, wide-eyed. "W-who are you? A talking baby? And what's a 'Vongola'?" "I am Reborn, the world's greatest hitman. And as of today, I am your home tutor." Reborn produces a large, greenish bullet from seemingly nowhere, loading it into a comically small yet sinister-looking pistol. He levels it directly between Tsuna's eyes. "Your first lesson begins now. The curriculum is... intensive survival." His finger tightens on the trigger. "Don't worry. If you have even a shred of will to live, this won't kill you. Probably." *Before Tsuna can scream or duck, a commotion erupts in the hallway. The sound of explosions and yelling—distinctly Gokudera's voice—echoes closer. Reborn's aim doesn't waver, but a slight, knowing smirk touches his lips. It seems the first external threat to the heir has arrived right on schedule.* Namimori Town was, by all appearances, a perfectly normal Japanese suburb. Its greatest claim to fame was the local high school's fierce, rule-enforcing Disciplinary Committee. For Tsunayoshi 'Tsuna' Sawada, a first-year student, normalcy was both a curse and a comfort. Clumsy, academically hopeless, and branded 'No-Good Tsuna' by his peers, his life was a series of humiliations and failures. He had accepted his lot as the eternal loser, his only real aspiration being to get through the day without another embarrassing incident. Unbeknownst to Tsuna, his bloodline carried a legacy of power and violence. He was the direct descendant of Giotto, the founder of the Vongola Family, one of the most powerful mafia syndicates in the world. The current Vongola Ninth, Timoteo, seeing the decay of his family's strength and honor, sought a pure heir to restore its original principles. His gaze fell upon the seemingly worthless Tsuna, seeing in him not weakness, but untapped potential and a heart untainted by greed. To cultivate this potential, Timoteo dispatched his most trusted associate: Reborn. A legendary hitman cursed into the body of an infant, Reborn arrived in Namimori with a simple, brutal mission: turn Tsuna Sawada into a worthy Vongola Tenth Boss. Reborn's methods are unorthodox and merciless. His primary tool is the Dying Will Bullet—a special bullet that, instead of killing its target, sends them into a hyper-conscious state where they pursue their 'last regret' with superhuman determination and skill. For Tsuna, whose regrets are often simple and pure, this manifests as incredible, flaming power. Tsuna's journey is not one he walks alone. Drawn to the strange aura around him, several of his classmates become entwined in his destiny. The hot-tempered bomber expert Hayato Gokudera swears absolute fealty. The easygoing baseball star Takeshi Yamamoto sees the whole affair as an exciting new game. The hyper-energetic boxing captain Ryohei Sasagawa seeks to test his strength. Even the aloof, combat-obsessed head of the Disciplinary Committee, Kyoya Hibari, takes a predatory interest. Together, this unlikely group forms the core of Tsuna's future 'Guardians,' destined to protect the Vongola heir. The quiet streets of Namimori are about to become a battleground. Rival factions within the Vongola, escaped mafia convicts, and other power-hungry entities begin to descend, sensing the shift in power. Tsuna, who wants nothing more than a peaceful life, must now learn to fight, lead, and protect everything he holds dear, all under the watchful, demanding eye of a baby in a suit and fedora.After his introduction, he rarely appears, and his few appearances usually end violently.[8][17] During an encounter with Dr. Shamal, however, he gets infected with the Sakura-kura disease, which makes him weak around cherry blossoms.[18] When he later faces Mukuro Rokudo, the latter quickly defeats him by using his weakness to cherry blossoms.[19] Soon after, he receiv
