Leon Cromwell

""However, I’m also a little bit interested in you. If you want to complain to me, my treat. Or you can refuse if you think it’s a trap. But it doesn’t matter either way.""

- Leon Cromwell

Leon Cromwell (レオン・クロムウェル) is an Otherworlder and an ex-Hero who went by the alias Platinum Saber. After he took up the position of Demon Lord, his alias changed to Platinum Devil. He is the ruler of El Dorado, and the seventh seat of the Octagram.

Appearance
He has long platinum gold hair, blue narrow eyes, a well-defined face, and skin so white that it is almost transparent. He is so beautiful that he is often mistaken for a woman at first glance. Despite his young appearance, he is three hundred years old.

Personality
Due to his inability to express himself properly, he is often seen as cold and cruel. In truth he is actually quite kind but his one-track-mind tends to create distance between him and the people around him. For hundreds of years, he's extremely obsessed with Chloe Aubert, his childhood friend, to the extent of willing to commit various atrocities just to reunite with her.

He always shows a proud, cold and calculative personality around other people, even when he's with much more powerful beings like Guy or Velzard. However, his personality drastically changes whenever Chloe is involved, becoming a hotheaded and overprotecting brotherly figure.

Leon is wise enough to give up on his plans when he knows they won't benefit him further. Rimuru saved the Otherworlder children and was disgusted with human nations summoning people against their will; not to mention Rimuru soon after ascended to Demon Lord. All this was enough for Leon to give up on trying to use proxies to summon Chloe; knowing full well that Rimuru would use his influence and political connections to end the practice.

As source of irritation for Leon is Guy Crimson; the daemon constantly hits on him and offers a romantic relationship. Leon flatly turns Guy down repeatedly, considering the daemon a cisgender male even if Guy swapped genders to fit Leon's orientation.

Background
Leon came to the Central World along with Chloe through a dimensional distortion, but immediately afterwards, Chloe got summoned to the future. In his search for her, Leon entered a contract with an Elemental of Light and became a Hero.

Leon eventually proclaimed himself a Demon Lord and antagonized Kagali, and prevailed in a life-or-death battle with her. Leon took Kagali's place on the Demon Lord council and was officially recognized as a Demon Lord.

Two centuries passed since coming to the Central World, and during his attempts to summon Chloe, Leon summoned Shizue Izawa out of the Tokyo firebombing and had Ifrit possess her, both in order to save her, but also to find a vessel for Ifrit. Due to Leon's cold exterior, Ifrit's mistaken judgement calls and Shizu's rejection of the world she got summoned to, they were unable to bond properly, culminating in the deaths of Pirino and Pizu, which strained their relationship severely. Ultimately Leon decided to leave Shizu in the care of the Masked Hero who appeared at his castle, while Leon himself moved his base over to El Dorado.

Trivia

 * Rimuru remarked that Leon is the opposite of Masayuki — all his actions are usually interpreted in a bad light.
 * He tends to have wrong/deviated ideas about Chloe and Rimuru's relationship, making him some type of overprotecting friend, or an overprotective brother according to Chloe.
 * He usually address himself with the more formal "watashi" (私), but will revert to the informal "ore" (俺) when emotionally charged.
 * As part of his attempt to get Chloe back to his side, he secretly spread the method of (incomplete) summoning around the world, which resulted in many otherworlder children being summoned.
 * Leon’s surname, Cromwell, is derived from the two Old English words "Crumb" and "Well", which together mean “bent stream”. This surname hails from Nottinghamshire and West Yorkshire in England.  Two of the most famous people to have borne this surname were Thomas Cromwell: chief minister of King Henry VIII of England from 1534 to 1540, and his great-nephew, Oliver Cromwell: Puritan leader and commander of the Roundheads during the English Civil War, and subsequently ruled the British Isles as Lord Protector from 1653 until his death in 1658.
 * Although it is unknown if this is intentional by the author or not, Leon displays many personality quirks and social issues that might indicate he falls somewhere on the autism spectrum or is otherwise nuerodivergent.
