On the ceremonial night when Hsien-ko and her sister, Mei-Ling, who were close to becoming Senjutsushi by their master, their village and people were attacked by a group of supernatural beings knows as Darkstalkers sent by Jedah Dohma. After their master was murdered, their mother gave her life to protect them, but because of this, her soul was trapped in darkness. To release their mother's soul from the darkness, Hsien-Ko turns herself into a Jiang-Shi (a Chinese hopping vampire). Mei-Ling turns into a ward to make sure Hsien-Ko doesn't lose control of her darker half that has been building inside her. The two set off to hunt down the Darkstalkers who attacked their people, and help innocent people as a Darkhunter.

Hsien-Ko is a respectful, goodhearted, and honorable person who opposes evil from a supernatural being. She has an intimate interest in men who seek to improve themselves and help others. This is often the reason why she does not have feelings for Lord Raptor. She is very protective when it comes to her family and the relationships she makes with others and dislike those who disregard their own humanity in search for absolute power. There is however a darker side to Hsien-Ko, as she holds a personal grudge to demons and those that hurt innocent people, and is afraid of the jiangshi trying to consume her mind. In moments she doesn't need to fight or in not-so-tense moments she seems to be somewhat clumsy.

Vocal range: medium-high. The ending shows them as children so please be able to a childlike voice as well.
