Clayman, crafted by the former Demon Lord Kazalim as a Deathman and member of the Moderate Harlequin Alliance under the alias "The Crazed Clown," was designed to ascend as a True Demon Lord. Rising among the Ten Great Demon Lords three centuries ago, he expanded his power through calculated alliances and manipulation, governing the Puppet Nation of Jistav—a realm enriched by lucrative trade and mystical artifacts. His dominion relied on coercive tactics: stealing hearts to bind subordinates with curses of eternal servitude, forming elite units like the Five Fingers. Beneath a poised, aristocratic exterior lay ruthless ambition and a penchant for treating others as disposable instruments. Loyal only to the Harlequin Alliance and Kazalim, he harbored an insecurity that fueled reckless ventures, such as engineering the Orc Disaster, manipulating Milim via the Orb of Domination, and provoking human-monster conflicts to amass souls for his ascension. Overconfidence in schemes like controlling Charybdis or deploying anti-magic barriers against Tempest ultimately revealed his weaknesses. Defeated by Rimuru’s evolution and the unraveling of his plots at Walpurgis, Clayman met his demise. Yet in *Clayman Revenge*, the Unique Skill "Retry" propelled him 70 years into the past, memories intact. Adopting caution, he pursued self-strengthening, restored Mjurran’s heart, enforced disciplined training, and forged alliances to evade past errors. This rebirth reshaped him into a tactician valuing loyalty, preemptively countering threats like the Hero Chloe Aubert. Relationships once marked by exploitation evolved. Post-time-leap, he earned allegiance through mutual respect, recruiting the demon Rain and artificer Sasha. His bond with Kagali—Kazalim’s reincarnation—endured, reflecting steadfast devotion. Interactions with Milim shifted from manipulation to an unanticipated camaraderie, her acknowledgment of him as a "friend" subtly influencing his growth. In battle, Clayman wielded "Puppeteer" for control and intelligence, "Martial Dance" for agility, and geomancy. Forms like Crazy Pierrot heightened aggression at the cost of vulnerability. The "Retry" skill introduced strategic foresight, tempered by dread of irreversible defeat. His legacy spans themes of hubris, redemption, and the transformative power of second chances.
