Shyao Lin

Shyao Lin and Rey had the same master, and always thought of each other as brother and sister. She is a sorceress, although she does not fight much. She became the master/mistress of the demon Ming Ling after saving her from Rey's hot temper. She is also the object of both Jaryoon and Rey's affections. However, later in the series, she is revealed to be Lady Sohwa, the sage in charge of destroying Rey, whose possession of the soul of Ban-Go causes him to be seen as a threat. Although Shyao readily accepts her fate as the Lady Sohwa and Rey's executioner, both she and the other sages know that killing Rey will affect her deeply. In the manhwa, her spells remain in their original language.

Shyao Lin slowly falls in love with Jaryoon as the series progresses, and both them conveyed their feelings to each other before Jaryoon's death at the hand of Shiyan (Volume 37), activating her "power" and helping Rey to defeat Shiyan. After Shiyan is defeated, she pray for both Hyacia and Rey's happiness.

Background
18 years old. A little bit naive, she has both Rey and Jaryoon eating out of her hand and doesn't seem to know it. Master Louran took under his wing five years ago, begore his death at the hands of the White Tiger. After meeting Rey, she became a self-professed older sister to him. Her real identity, however, is Rana, the Lady Sohwa, one of the eight Sages of the Heavenly Realm. Though Rana would have been classified as an "Ice Princess" type, her experiences as Shyao Lin have begun to slowly change her personality.

Rana stiil loves Rey, but tries to kill him out of a sense of duty. This decision would likely cause her intense guilt.... Even many of the fans are against her now.
