Hsien-ko (katakana: レイレイ, hanzi: 泪泪) is a video game character from the fighting game series Darkstalkers.
Hsien-ko was born around the 1730s with a twin named Mei-ling. During this time, ghosts and spirits of the dead arose from their resting places and attacked a rural Chinese village.
After their mother was killed by a powerful demon, she and her sister decided to use Tensei-no-Jutsu to save her, but they used a prohibited sub-division of this technique, Igyo Tenshin-no-Jutsu, and fought to release their mother's soul from the dark. This turned the twins into a jiangshi (僵屍), a type of Chinese vampire. This, however, also gave the two unusual abilities that later makes Hsien-ko capable of wielding a pair of giant mechanical arms which the two use to fight for their purposes. Mei-ling is later transformed into an ofuda on Hsien-ko's hat.
