Little Brother

Tsuna's mother is assassinated when he's one and a half, so he gets taken to Italy by his father. Iemitsu is a very busy man, though, so little Tsuna is raised mostly by his cousins – Vongola Nono's sons – and the household staff. He grows very close to all four of them, but then when he's six the cradle happens, and his father chooses to send him back to Japan to live with his mother's sister – who's a successful artist – rather than keep him in Italy where the Family's enemies have suddenly become more bold with Xanxus' disappearance.

This story is abandoned. I'm considering a rewrite, but I wouldn't hold my breath if I were you, it probably won't happen for a while. Sorry!
