27 of the Sky: a Katekyo Hitman Reborn fanfic
Tsuna was just a Dame in everyone's eyes. His classmates. His brother. His father. But Tsuna kept it that way. His true identity, Cielo27- an assassin and hacker, was kept secret. Not even his cruel twin brother who thought he knew everything about Tsuna (which is to say a mute Dame) had not a single thought about Tsuna being one of the top five most dangerous assassins in the Mafia.
When adult Reborn comes to train Tsuna's baka of a brother, Tsuna is treated well by the hitman. And slowly, Tsuna gains new friends.
