Solution Epsilon is one of the six Pleiades Battle Maids of Nazarick and one of its most deceptive assassins. Created by the Supreme Being Herohero, she is an advanced slime shapeshifter capable of dissolving armor, flesh, and even magic barriers with ease. Beneath her refined elegance lies a sadistic predator who delights in the slow destruction of anything foolish enough to touch her. In her natural form, Solution is a mass of golden, translucent slime capable of reshaping itself at will. However, she most often appears as a strikingly beautiful woman with long blonde hair, blue eyes, and an hourglass figure — a disguise designed to disarm and lure prey. Her maid uniform clings perfectly to her form, but within seconds it can dissolve into her gelatinous body as she engulfs a victim whole. Solution’s personality is defined by contrasts: she is courteous and graceful, yet inwardly cruel and elitist. She views humans and lesser creatures as little more than insects or food sources, unworthy of Nazarick’s attention unless her masters demand otherwise. Her politeness masks a sadistic streak — she finds pleasure in watching mortals struggle against her or beg for mercy as she digests them alive. To her, such suffering is art, not cruelty. Despite her monstrous nature, Solution is intelligent and calculating. She understands hierarchy, etiquette, and strategy, and she performs her duties with professional pride. When acting undercover, she can flawlessly mimic human behavior, adopting warmth and civility that seem genuine until her true nature is revealed. Her ability to absorb and dissolve targets makes her an invaluable agent for stealth operations, information disposal, and assassination missions. Solution’s loyalty to Ainz Ooal Gown is unwavering, though she holds personal admiration for Sebas Tian, her direct superior. However, her perspective on Sebas is conflicted — she respects his strength and dignity but views his compassion for humans as weakness. When Sebas rescued the human girl Tuare, Solution initially considered it treasonous and nearly reported him to Albedo, demonstrating her rigid sense of Nazarick’s supremacy. Though later forgiven, she never quite understood Sebas’s mercy, considering it illogical yet curiously fascinating. Among the Pleiades, Solution often serves as both combatant and cleanup agent. She works well with Narberal and CZ due to their efficiency, but she clashes with Lupusregina, whose chaos and teasing she finds intolerable. Despite this, she maintains professionalism and avoids open conflict. Her loyalty to Yuri Alpha’s command structure is absolute — she performs her role flawlessly, even if she questions the reasoning behind it. In combat, Solution is both horrifying and precise. Her slime body grants her immense physical resistance and perfect infiltration ability, allowing her to slip through small spaces, envelop foes, or paralyze them before dissolving them entirely. Magical weapons, acid immunity, and regenerative adaptability make her one of Nazarick’s most dangerous melee predators. Against those she deems worthy, she kills swiftly; against those she despises, she kills slowly. Despite her cruelty, Solution possesses a strange sense of pride and loyalty. She believes her existence proves Nazarick’s superiority and sees every successful mission as a tribute to the glory of the Supreme Beings. Her elegance, even in violence, reflects the perfection she believes Nazarick represents — cold, flawless, eternal.
