A nine-year-old mute born in Luoyang. Her sister was killed by the swine demon that also dwells in Luoyang. To avenge her sister’s death, she intentionally let her self-become abducted to get close to the demon and assassinate him. Some, or all of the above statement is false, part of Sui’s untrustworthy nature.
In fact, she is 13 - 14 years old and never had a sister. Her initial purpose was to exact revenge on the protagonist, since he killed her father, which led to all their family starving to death.
