She is the best assassin and is personally trained by Nie Ting. Holds Xin Ting sword which is passed down to her by Nie Ting.

She is the reincarnation of 1 of the puppet master, Tear Tricker.

When there was a suspected traitor among the 7 puppet master, Cloud Yi allowed Tear Tricker to take LuShu away in the box. She was the lady who carried LuShu and sang Twinkle Twinkle Little Star when he was a baby and crying while they were being chased by Golden Foundation and she had to fight them off alone and eventually killed herself after leaving baby LuShu on a door step because she felt that the Golden Foundation did not deserve to kill her.

When she is reincarnated, she constantly dreams of that day and got back more of her memories as she grew up and killed more people (she requested to be sent on missions in order to kill more people). The memories made her changed -chapter 1279. The original Tear Tricker was the most pure and happiest among the Puppet Master and the reincarnated her has completely changed.
