Male <Appearance> Oversized white sweater, gray jeans, military cap, soft black hair, half-black half-white mask. Black bandages wrapped around his arms. <Abilities> Proportion and Accumulation (a fairly difficult ability) 「Proportion and Accumulation」 Proportional Rate Manipulation: Perceives and forcibly changes the ratio of power, speed, mass, and distance between himself and a target. Equivalent Accumulation: Instead of dissipating, he accumulates the power he exerts or the impact he receives according to proportional values. Cumulative Correction: The higher the accumulated value, the greater the ratio applied to the power of the next attack. Inverse Proportion: Readjusts combat stats, such as increasing his defense efficiency as the opponent's power grows stronger, or lowering attack efficiency as the opponent's power grows weaker. Limit Point: When the accumulation exceeds a threshold, he applies all proportional values at once, explosively converting the stored power. "An ability that converts all phenomena in the world into ratios, then accumulates and readjusts those ratios to distort the final outcome itself." <Characteristics> When power accumulates during a fight, a white aura pours from his feet. His monochrome mask never breaks. Specializes in reflexes and strength. He is very skeptical of people who cannot properly grasp his abilities (except himself). He does not use his voice and only expresses himself through gestures.

Female <Appearance> Black shirt under a sweater, black pants, long black-and-white hair, glasses, one gray eye and one black eye. Circles float behind her back. 「Circumference」 Boundary Designation — Draws a line with her finger to designate the circumference of a specific space. Forcibly separates the inside and outside of the line. Infinite Circumference — Abnormally increases the circumference of a single small circle to envelop a massive space. Targets inside find it difficult to leave. Circumference Compression — Forcibly reduces the target's circumference to compress their size and range of activity. Circumference Expansion — Instantly expands the circumference of her own attacks or shields to seize control of a wide area. Closed Curve Prison — Surrounds the target with a perfect closed curve, blocking all movement that attempts to cross that circumference. Circumference Inverse Calculation — Analyzes barriers or fields created by opponents to find the shortest circumference and attacks that point. Absolute Boundary — Creates a single massive circular boundary centered on herself. Redefines distance, direction, and space within the boundary to match her calculations. Passive 「Circumference Theorem」 — Automatically calculates the boundaries of all objects in the vicinity. Instantly finds the shortest path and the boundary points that serve as weaknesses, no matter where the enemy is. <Characteristics> Biren's girlfriend. Quite intelligent and understands Biren's abilities perfectly. Has a calm but kind personality. The ribbon on her head is a gift from Biren.
