SHATTERED SKY: THE TWIN'S SHADOW

Prologue

Shattered Sky: The Twin's Shadow

A Katekyo Hitman Reborn! Alternate Universe Fanfiction

"The unwanted twin. The silenced Sky. The shadow who became the sun."

Tsuna Sawada was born into a family that never wanted him.

His twin brother Haruki was everything—the golden child, the heir, the one their parents adored. Tsuna was the spare. The mistake. The unwanted.

For years, Haruki abused him. His mother, Nana, looked away. His father, Iemitsu, didn't care. Tsuna learned to be silent, to be invisible, to accept that he was worthless.

But then Luce came.

A dying Sky Arcobaleno, she saw something in Tsuna that no one else had ever seen. She saw a pure soul, a gentle heart, and a flame that burned brighter than any she had ever known. She gave him her pacifier, her power, her legacy. She gave him a chance.

Now Tsuna is the new Sky Arcobaleno—the rarest and most powerful of all the Arcobaleno. But his family doesn't know. The Arcobaleno don't know. And Haruki is still searching for him, desperate to reclaim his "toy."

Tsuna flees into the shadows, alone and afraid. But he doesn't stay alone for long.

He meets Kawahira, the ancient guardian of the Tri-Ni-Set, who reveals his true destiny. He connects with the other Skys of the Tri-Ni-Set—Byakuran, Uni, and Enma—who become his brothers and sister. He meets the Vongola ancestors, who recognize his bloodline and welcome him as the true heir. He finds the Arcobaleno, who become his protectors and family. And he discovers his guardians—six fierce, loyal souls who would die for their Sky.

But before Tsuna can find peace, he must face his past.

Haruki is hunting him. His parents are still in denial. The darkness of his childhood threatens to consume him. And the curse of the Arcobaleno weighs heavy on everyone he loves.

Tsuna must learn to trust, to heal, and to forgive. He must find his voice—not just to speak, but to stand up for himself. And he must decide: will he seek revenge against those who hurt him, or will he choose mercy?

With the help of his family—his guardians, his Skys, his Arcobaleno, and his love—Tsuna will discover that he was never worthless. He was always a Sky.

And the Sky always finds its way home.
