— Mu Duiying
Mu Duiying is 80th ranked Star Maiden.
Little Restrained was an assassin, after all, not very good at direct confrontations.
Wrapped in black night clothes, her posture was graceful, her hands and feet equipped with fishnet style pads and stockings, and she had a pair of gleaming purple eyes.
Talkative and a bit dumb. The Little Restrained should have been called Unrestrained. To speak of it, her mouth was truly unrestrained, incoherently speaking in excitement. Those who knew would believe this was happiness that grew from the bottom of her heart from soaring through the skies on a Flying Sword for the first time. Those who did not know would believe a lifelong spinster had encountered a rapist.
She first meets Su Xing when he attempts to catch her Star Beast and keep it as a pet. After being convinced by Mu Duiying, Su Xing helps her with capturing her Star Beast. Grateful, she shows him the location of Tang Lianxin's Star Beast. There, they end up meeting Jin Qiongyu and Song Qingci's Uprising group.
This Guardian Star honestly was dedicated. She obviously knew she basically could not possibly be the Killer Star’s opponent, yet she still was unwilling to concede defeat. Only because of a vague promise, Su Xing honestly was somewhat in admiration. She helps Su Xing and Tang Lianxin escape from Song Qingci's Uprising group, leaving soon after they escape.
