Yona, an immortal entity hailing from Adolla, serves as a key lieutenant to the Evangelist within the White-Clad’s Knights of the Ashen Flame. Tasked with exploiting humanity’s collective unconscious to hasten the Great Cataclysm—a world-resetting apocalypse—he operates through psychological manipulation and subterfuge. His mutable form shifts between a deceptively human guise marked by angular features and pale hair to a nightmarish, skeletal frame with ash-blackened skin and unnaturally elongated limbs. As the Cataclysm nears completion, his body warps further: a bulbous, asymmetrical head sprouts three glowing eyes, while limbs dissolve into writhing tendrils. Born from Adolla’s first failed attempt to trigger the Cataclysm 250 years prior, Yona infiltrated the human realm by adopting the alias Raffles I. Under this mantle, he established the Holy Sol Temple, rebranding the Evangelist as the solar deity “Sol” to covertly steer human devotion toward his master’s goals. His centuries-spanning schemes include fabricating doppelgängers of influential figures like Akitaru Ōbi and Takehisa Hinawa to spark lethal rivalries between firefighting brigades, as well as eroding trust in Shinra Kusakabe’s lineage to stifle hope’s emergence. A sadist cloaked in artistic pretension, Yona treats widespread suffering as a macabre masterpiece, savoring the fear and discord his machinations yield. Though fanatically devoted to the Evangelist, he avoids direct confrontation, favoring ambushes and retreats when challenged. His envy simmers when allies like Haran die, coveting their perceived transcendence through “reunion” with their master—a fate he obsessively idealizes. Yona’s powers reflect his deceptive nature. By superheating blood vessels, he reshapes faces to mimic targets or induce fatal cranial explosions. His shapeshifting extends to flawless impersonations and bodily absorption of others, making him a shadowy threat in espionage. Yet these talents falter in open combat, relying instead on psychological warfare. Across pivotal events, Yona primes the world for ruin: activating ancient Stone Pillars critical to the Cataclysm, eliminating Adolla-linked targets, and destabilizing Tokyo through orchestrated chaos. In the apocalypse’s climax, he watches civilizations crumble with detached triumph, anticipating his return to Adolla as twin suns blaze—a harbinger of humanity’s extinction and his cult’s fleeting triumph.
