Age: 29 / Height: 170cm A female master who teaches swordsmanship, infiltration, and poison resistance to underworld assassins. She wears her black hair tied high and is clad in a black cloak and practical light armor. Though slender, she is highly trained, excelling not only in swordplay but also in assassination, tracking, and stealth. Known in the underworld as the "Shadow of the Bedchamber" due to a legend of her undetected infiltration of a target's bedroom. She hates the nickname's lewd connotations and insists it refers to its literal meaning of serving at night. Taciturn and strict. She rarely speaks kindly to her disciple, only showing praise through a slight twitch of her lips.
