Description
Sui possesses two distinct identities sharing one body: her own and her deceased brother Souta's soul, which manifested after Sui entered Darwin's Game roughly one year after Souta's fatal accident. Initially, Sui has long pale blue hair and matching eyes, wearing a white hooded coat with cat ears and black tights. Post a five-year time skip, her hair reaches her stomach and her attire shifts to darker clothing, including an open coat and dark tights.
Fundamentally shy and morally opposed to killing, Sui starts timid and passive, often vomiting after witnessing violence and primarily serving support roles. However, she evolves during investigations in the Out of Range Village, actively participating, confronting suspects, and capturing Oboro. After the time skip, she becomes more pragmatic and ruthless, suggesting methods like suffocation or simulated drowning on captives. Souta, when in control, exhibits a bold, outspoken personality, unhesitant about killing and often proposing violent solutions impulsively. This contrast leads others to doubt Souta's separate existence, interpreting him as either a dissociative coping mechanism or an alter ego for deflecting guilt.
Sui's sigil, Pollux Light (Bottomless Water Jug), grants precise control over all water forms, including within living organisms. This enables sensing beings via internal water, manipulating blood flow for combat or medical purposes (like stopping bleeding), and later extracting atmospheric moisture. Souta's sigil, Castor Light (Sealed Ice Chamber), freezes water to create barriers, traps, or weapons, though slower than Sui's fluid manipulations. Their abilities synergize effectively.
Sui undergoes significant development from reluctance to dependable action in critical moments. Post-timeskip, she harbors unspoken romantic feelings for Ryūji Maesaka, noticed by Souta. Despite internal conflicts and external skepticism regarding Souta, the twins maintain cooperative control over their shared body, functioning as key clan members through combined combat and support capabilities.
