Demon Mikaela's entire thing is built on this brutal inversion of celestial purpose. He's not your typical fallen angel snarling about rebellion; he fell because his devotion was too absolute. In 'Supreme Magus', he starts as a being of pure light tasked with guarding the balance, but his rigid adherence to duty and love for his creator curdles into something monstrous when he perceives a threat to that order. His drive isn't powerlust in a vacuum—it's a twisted form of worship, a need to purge imperfection from existence even if it means becoming the very corruption he hates. That's what makes him compelling. It's not about being evil for evil's sake. The fall happens because he can't reconcile free will with divine plan, so he takes it upon himself to 'fix' things, descending into a logic so cold it burns.
His arc is essentially a tragedy of extremes. Every step he takes towards his goal of a 'perfect' world strips away another layer of his original grace, yet he'd argue he's the only one still truly faithful. The internal conflict is mostly gone by the time we see him in the story; he's reached a point of serene, horrifying conviction. What readers often debate is whether he's a villain or an antihero gone completely off the rails. The drive is this unshakeable, fanatical belief that his path is the only salvation, making him far scarier than a demon who just wants to watch things burn. He's a missionary with hellfire.
