Sun Luyu (onyomi: Son Roiku) is the youngest daughter of Wu Emperor Sun Quan. She became embroiled in a political dispute with her older sister Sun Luban who framed her for conspiring against the regent Sun Jun, leading to her execution. Her design theme in Blast is meant to evoke the image of a young girl with a doll-like expression. In contrast to Sun Luban, she is given her father's style of outfit and her mother's hair.
