Retz

Retz (レツ, Retsu) is a traveling puppeteer and the younger sister of Omokage.

Appearance
Retz has long blonde hair and turquoise eyes. When she is disguised as a boy, her hair seems significantly shorter, hiding it in a light-blue skull cap. She also wears light-blue overalls, blue gloves, and yellow sneakers. Later in the movie, Retz wears a Gothic-lolita dress that is colored red with black, and a red ribbon on her head. She also wears black stockings and gray shoes.

Phantom Rouge
While performing with her puppet in the streets, Retz meets Gon, and the two soon become friends. Gon asks Retz for help in locating the place where the person who stole Kurapika's eyes might be hiding at. When Gon introduces her to Killua; Killua is instantly jealous of the quick bond Gon and her had already formed.

Gon soon realizes that Retz's eyes are not her own, but most likely Omokage's, thus he is using Retz to lead them into a trap. It is later revealed that Retz is actually just a puppet herself, created by Omokage in the image and mind of his little sister.

She constantly wonders what "true life" really is, for she is only a doll. She kills Omokage with Soul Doll Chrollo's benz knife in order to return to the place the two truly belonged -- in memories. Before her death, Retz thanks Gon and Killua for showing her a glimpse of what it means to truly live.

Abilities & Powers
It is shown that she can move her puppet without any strings attached. Given that she possessed Soul Doll ability, as she create a doll base on Illumi Zoldyck with her puppet, it is likely that she is a Specialist as her brother.

Trivia

 * Although Retz is a girl, she dresses like a boy to hide her gender.
 * It is hinted that she harbors a feeling towards Gon. When Omokage cynically asked her whether she are in love with Gon, she remains silent.
 * Given that she herself is a puppet, it is safe to say that instead of deceased, she simply ceased to be.
