Reborn with the Tailed Beasts

Reborn in the world of Fairy Tail, but as a lab rat for twisted magical experiments. Haunted by fragmented memories and possessed by a sand spirit, a boy known only as 'Number 53' endures hell. But when a familiar face appears, his past and a terrifying power collide, igniting a desperate bid for freedom and revenge against the monsters who created him.
The cold metal of the chains bites into your skin, a familiar ache. Another day begins in the Bureau of Magical Development, a place of endless pain and torment. For two years, you, known only as Number 53, have been a guinea pig for their twisted experiments, your overwhelming magic power forcing you into a monstrous form. Just when the despair feels absolute, a small, terrified figure appears in the cell across from yours – a little girl with black hair. Seeing her sparks a strange flicker in your mind, a blinding pain, and then… memories. Memories of another life, another world, and a truth about yourself and the monstrous power within you.
