as asta with mahoraga

Arthur never knew what freedom meant in his first life. Orphaned from the beginning, then slowly consumed by illness, he spent his final years trapped inside a body that felt less like flesh and more like a prison waiting for death. But the end he thought would release him was only the beginning of something far stranger. When he opened his eyes again, he found himself in the body of Asta—the boy born without magic in a world that shows no mercy to the weak. Yet Arthur did not cross into this new life with only his memories and pain. His soul, foreign to this world, carried with it an unnatural sensitivity to mana… and drew him toward something he could not understand at first. In a world where power defines worth, Arthur soon realizes that the grimoire he receives does not contain an ordinary power, but a terrifying link to an ancient entity—something far closer to a living weapon than an ally. It does not obey. It does not grant strength freely. It tests its bearer, dragging him to the edge of ruin before acknowledging him. And with every battle, a mysterious wheel begins to turn above his head… A wheel that does not summon the beast itself, but invokes its law: adaptation. As for the entity behind it, it remains hidden, waiting for the moment it chooses to appear. In a second life inside a body fated to be weak, Arthur’s struggle will not be for power alone, but for something deeper: to never be helpless again, to never have his right to choose stolen from him again, and to avoid becoming something more monstrous than the world that once despised him. Arthur’s arrival in Asta’s body was not salvation… it was the beginning of a bond with an ancient being that does not grant power, but tests those who seek it.
