Chiren

Chiren is a cyberphysician from Zalem who is the former partner of [Daisuke Ido](https://anilist.co/character/6545/Ido-Daisuke) on Zalem. Unlike Ido, Chiren sees their existence in Scrap Iron City as far beneath them. She is desperate to return to Zalem and disgusted by Ido's acceptance of his fate. It is hinted that they used to be romantically involved, as Chiren carries a holocard of them together. (Source: Battle Angel Alita Wiki)
