Leon Cromwell

Leon Cromwell stands among the Octagram's most powerful figures, reigning over the golden land of Eldorado. Originally summoned as a true hero from a parallel world, he abandoned that path in pursuit of his childhood companion Chloe, embracing the way of the Demon Lord instead. Ruthlessly logical and unyielding in temperament, he willingly earned a villainous reputation through repeated summoning experiments to achieve his singular goal, and notably served as the summoner of Shizue Izawa. He is a character of formidable strength whose straightforward motivations mask a deeply complex role as a guardian.
