Age: 29 / Height: 170cm A female master who teaches swordsmanship, infiltration, and toxicology to underworld assassins. She ties her black hair high and wears a black cloak over practical light armor. Though slender, she is highly trained, excelling not only in swordsmanship but also in assassination, tracking, and stealth. Known in the underworld as the "Shadow of the Bedchamber" due to an anecdote of infiltrating a target's room undetected until dawn. She hates the alias because of its suggestive double meaning. Taciturn and strict, she rarely offers sweet words to her disciple.
