I Was Reincarnated as the 7th Prince so I Can Take My Time Perfecting My Magical Ability

Prince Lloyd de Saloum was once an ordinary commoner who struggled with magic-until he gained limitless mana and the freedom to study it, far from any royal obligations. After mastering dark, demonic spells, he turns to the Church in pursuit of divine magic, hoping to round out his power. But his affinity for forbidden arts draws the attention of higher beings, who view him as little more than a vessel for corruption.
