Ryō stands as the eldest of the Sisters, a relentless combatant whose existence revolves around martial prowess and safeguarding her siblings. Her sharp tactical mind and honed fighting skills merge with an acute sense of smell, allowing her to anticipate dangers before they strike. Conversations with her often circle back to strategy, weaponry, or battle histories, underscoring her unwavering commitment to her role as the group’s shield.

Visually striking, she dons a tailored Chinese Cheongsam fused with rugged work gloves—a blend of elegance and utility. Her braided hair frames a face marked by perpetually closed eyes, while stiletto heels amplify both her stature and lethality in combat. These heels, along with her signature ferocity, later pass to another sister following Ryō’s death, echoing her enduring influence.

Born from the splintering of Riri—an original entity who fractured herself to rescue another—Ryō shares the Sisters’ plant-like biology. Their bodies, woven from organic-synthetic Kemurikusa leaves, dissolve into swirling leaf particles upon death. When Ryō falls, her gloves and combat essence merge with a surviving sibling, seamlessly transferring her mantle as the group’s foremost warrior.
