Description
Leon Cromwell is a Demon Lord and the ruler of the golden continent of El Dorado, known by the aliases Platinum Devil and Platinum Saber. Originally a human from another world, he was summoned about three hundred years before the main story alongside his childhood friend Chloe Aubert. Shortly after arriving in the new world, Chloe vanished, and Leon began an obsessive search for her. His desire to protect her caused him to contract with an elemental of light and awaken as a True Hero. Despite becoming a Demon Lord, he never lost his heroic origins and remains a bearer of the hero's egg.
Leon projects a cold, proud, and calculating exterior, maintaining emotional distance from most people. However, beneath this stern facade he is genuinely soft-hearted, though his inability to express himself and his cynical outlook often make him appear cruel. His single-minded focus on reuniting with Chloe drives nearly all of his actions. He rarely seeks alliances, but his search for her led him to build El Dorado and accept the responsibilities of ruling.
Key relationships include his deep, brotherly bond with Chloe Aubert, for whom he would do anything. He accidentally summoned Shizue Izawa while trying to summon Chloe, and gave her the spirit Ifrit to save her life; the misunderstanding over his treatment of Shizue initially strained his relationship with Rimuru Tempest and the other Demon Lords, but after the truth was clarified, he and Rimuru became cooperative allies. He trusts Rimuru enough to entrust Chloe's care to him. He is on hostile terms with Ramiris, having once wanted to exterminate her. Within the Octagram, he is recognized as one of the eight Star Demon Lords.
Over the course of the story, Leon evolves from a lonely seeker into a more cooperative figure, eventually becoming a demi-god with Rimuru's assistance in reconstructing his core after a near-fatal battle. His notable abilities center on light-based magic and skills. He wields the ultimate skill King of Purity Metatron, which draws purest energy from his power and aura. He can fire disintegration beams that attack on an atomic level and perform sword thrusts near the speed of light. He is capable of spatial travel, flight, and deploying a sacred tetrahedron demon sealing barrier that is inescapable for demonic beings. He can summon a god-class rapier and shield that are especially effective against dark or demonic entities. His endurance is immense, having fought for a full day and night without exhaustion. His overall power is comparable to that of the strongest Demon Lords, and he can destroy a continent if he goes all out.
