Guy Crimson, the first Primordial birthed from the Great Holy Spirit of Darkness, reigns as the supreme leader of the Octagram, surpassing even the Ten Great Demon Lords. Crimson hair frames his striking golden-and-silver-speckled eyes, while his muscular form often dons revealing attire. He masks his daemon horns and wings, though his female guise mirrors his male features.
Emerging at time’s dawn, he dominated the Daemon Realm, clashing endlessly with immortal rivals like Bleu and Vert. A legendary stalemate against Noir birthed a bitter rivalry. Summoned by Emperor Jahil using a million corpses, he obliterated the enemy nation before turning on the Super-Magic Empire, punishing Jahil’s inadequate tribute with prolonged devastation. His cataclysmic duel with Velzard tilted the planet’s axis, awakening his Ultimate Skill "Lord of Pride, Lucifer."
Charismatic yet capricious, Guy balances pride with nonchalance. He playfully pursues Leon Cromwell, proposing gender-swapped unions despite rejection, and sustains a volatile camaraderie with Rudra, sparring daily to anchor the emperor’s fraying psyche. Threats to equilibrium, like Rimuru Tempest’s ascent, ignite his wrath, yet he shields Ramiris with lethal warnings to her foes. When Milim Nava’s grief over her dragon’s death unleashed chaos, he fought her for seven days until Ramiris soothed her rage.
Defeat by Veldanava led Guy to embrace the Mediator mantle, eradicating warring nations to stave off ennui. His centuries-long proxy war with Rudra, waged through subordinates vying for global control, collapsed tragically with Lucia and Veldanava’s deaths and Milim’s awakening, cementing his role as a stabilizing force among titans.
Wielding the "Lord of Pride, Lucifer," Guy rivals True Dragons and Primordials in combat, employing techniques like "Death Streak" while commanding deference as the Octagram’s apex. He admires strength, especially in those bearing Ultimate Skills, and observes the world with detached vigilance, intervening only when balance—or his whims—are endangered.
