Skirk is a mysterious swordswoman who dwells in the darkest corners of The Abyss, and a strict teacher with a soft spot for the defenceless. She is capable of utilising a technique dubbed "Foul Legacy", which involves a strenuous physical transformation. She's an exceptionally dangerous combatant who is capable of using several weapons and possesses pale skin, red eyes, silver hair and a tall athletic build. Her outfit resembles fish bones, and barely covers up her numerous scars.
