Fairy Tail: Cursed by the Time God at the Start

Chronos thought he'd mastered time magic—until the God of Time cursed him for it. Stripped of his powers in the world of Fairy Tail, this transmigrator refuses to stay down. If he can't break the curse, he'll weaponize it. Dragon Slayer magic? Devil Slayer magic? Too mundane. Chronos sets his sights on something far more dangerous: the forbidden power of the gods themselves. In a world where magic is everything, he'll prove that a curse can become the ultimate weapon.
