- "You disgust me!"
- — Siena
Siena (シエナ, Shiena) is a new character making her debut in the rebooted Soul series timeline. Soulcalibur VI is when she makes her first appearance along with her older brother, Remiel. She is nicknamed The Red Hand.
Siena is a brown-skinned woman with darker brown hair and grey eyes. Her hair goes down to her neck, and curls in places. Her primary outfit consists of a mostly red dress accented with white and gold. On her hand are two white gloves, and her shoes are black with red roses attached to the outer ankles. Under the dress she wears a black corset and silver, laced thigh-highs. Around her neck and resting partially on her shoulders is black lace held in place by a red ribbon and tied together at the front with a red rose to match her shoes.
- Needle- This is Siena's main weapon that her father had forged for her in secret. The rapier was given the name "Needle" due to how thin and pointed the main blade is, but also as a guise to hinder others from realizing it is a blade.
