Sho Kusakabe possesses white hair, bright crimson eyes, and an angelic youthful appearance, standing 145 cm tall with a December 25 birthdate. Born through a virgin birth to Mari Kusakabe, he is Shinra Kusakabe’s younger brother. At age two, his Adolla Burst ignited during a fire that consumed their home, transforming Mari into an Infernal and enabling his abduction by Haumea and Charon. Raised by the White-Clad under the Evangelist’s influence, he grew viewing the cult as his sole parent. As the Third Pillar, Sho commanded the Knights of the Ashen Flame with detached authority, prioritizing efficiency over emotion. His combat prowess centers on a katana wielded with precision, favoring non-lethal strikes using the blade’s flat side or sheath. His Severed Universe technique halts universal expansion, granting near-instantaneous movement countered by debilitating cold that forces periodic pauses. A clash with Shinra triggered an Adolla Link, flooding Sho with suppressed memories of maternal love and their fractured past. Emotionally awakened, he rebelled against the White-Clad, only to be subdued by Haumea’s mind control, which erased his newfound humanity. Breaking free a second time, he abandoned the cult, adopting civilian attire and exploring the world with naive curiosity. He later reunited with Shinra, pledging to shield him as a guardian angel and thwart the Great Cataclysm. Initially reliant on the Evangelist’s grace, Sho’s Adolla Burst grew independent as reality merged with Adolla. His superhuman speed and strength allow feats like shattering concrete and overpowering foes such as Faerie and Joker. In the conflict’s climax, he joined Shinra in Adolla, aiding efforts to avert global collapse. Critical junctures define his arc: accidentally impaling Shinra mid-battle, reconciling tearfully with Mari’s spirit in Adolla, and defying the Evangelist’s designs. Once a ruthlessly detached weapon, Sho evolved into a protector driven by rediscovered kinship, balancing ethereal poise with resolve to forge his own path.
