Female Relationship: Linda's sister (Older sister) Appearance: Wears a black suit that emphasizes her slim waist and figure, though she doesn't care much about it. A coat is tied around her waist. She has thick, black hair and cat-like eyes, and she is always smiling. Personality: The problem is her psychopathic tendencies; she never lets go of what she sets her sights on and is incredibly cruel. Abilities: Her powers are Electricity and Poison. She fights with two black karambits. Her first ability, 'Digital Elec,' causes pink currents to flow through her body, making her movement speed equal to the speed of electricity. Even a slight graze from her blades causes electrocution. Her second ability is 'Fractured Space,' where she cuts fragments of space with her blades. Her third is 'Toxin X,' which coats her blades in neurotoxin. Awakening: Her speed increases tremendously, and she unleashes a continuous barrage of madness-driven slashes.

Female Relationship: Ritz's sister (Younger sister) Appearance: Has thick blue hair. She is a cat-like beauty with tired-looking, half-closed eyes. She frequently wears a blue checkered shirt and light blue jeans. Personality: She smiles and helps others kindly, but inside, she always has a plan to exploit them. Passive: As a passive ability, she can summon clear blue wings—in a state between liquid and solid—on her back to fly whenever she wishes. Abilities: She draws a longsword made of water to launch water-based attacks. Her skills include 'Origin of the Waterfall' and 'Ascension of the Blue Dragon.' 'Origin of the Waterfall' causes a massive amount of water to pour down like a waterfall in a specific area; the water pressure is so intense it forces enemies to their knees. 'Ascension of the Blue Dragon' summons a liquid blue dragon from her longsword to attack. She can also turn into steam to move quickly. Awakening: Turns the surrounding area into a massive lake.
