Suphia serves as one of the Three Beastketeers in the Beast Kingdom of Eurazania under the former Demon Lord Carrion. Known as the White Tiger Claw, she is a lycanthrope whose combat rank rose from Special A to S following significant events. Her humanoid form features long white hair, cat-like eyes, and a lean build. Partial transformation retains humanoid features while adding feline attributes like paws. Her full beast form manifests as a large, nearly scale-covered white tiger with serpentine eyes, horns, and a tail replacing legs; openly displaying this form is considered brazen among lycanthropes, reflecting her bold nature. Personality-wise, Suphia exhibits bluntness, aggression, and a fondness for combat, often testing opponents through fighting. She initially disdained humans but revised her views after encountering stronger individuals like Youm. She uses the masculine pronoun "ore," reinforcing her tomboyish demeanor. She enjoys alcohol and festivities but notably dislikes getting wet. Her abilities include lightning manipulation, channeling electricity through her claws. Her beast form significantly enhances physical power, speed, and durability. She clashed evenly with Shion during an early diplomatic envoy to Tempest but later struggled against high-tier opponents like Father Middray. Suphia began as Carrion's subordinate and student, holding deep respect for him. As an emissary to Tempest, she instigated a fight with Shion to gauge the nation's strength, leading to mutual respect. She later aided Tempest against Clayman's army alongside other Beastketeers. After Carrion's awakening and Eurazania's integration into Tempest, she remained as head of the reorganized Flying Beast Knights, succeeding Albis. Key relationships include her close dynamic with fellow Beastketeer Albis, despite occasional irritation over Suphia's eagerness to fight. She respects Rimuru Tempest after witnessing his power, eventually serving under his command. She is romantically involved with Gabiru.
