Jim Cleeas (ジムクリーズ, Jimu Kurīzu) is the creator of the mother keepers and works in Heaven's Tower to maintain them.
Jim has dull purple hair, at the start of the manga is was very long but she cuts it off. She has blue eyes and a beauty mark on her chin. Jim wears an extremely short black dress that unzips at the front with a lab coat over it.
Jim tends to come off as cold, harsh and sometimes out right violent. She doesn't care for people being ungrateful or trying to put her down and never backs down. She tends to be kinder towards Syal and reassures her.
Jim rescued Syal on a whim when she found her dying of a stab wound and begging for someone to save Elsa. Jim misunderstood and saved Syal instead, turning her into a mother keeper. Syal got angry at her for it upon initially waking up but calmed down after Jim shouted at her and made her realise Elsa wanted her to live. Jim is nicer to Syal than most people, letting her wander around in the slums rather than making her stay in Heaven's Tower and reassuring her she didn't need to be sorry for accidentally stabbing her.
Jim turned Lint into a mother keeper after he was given the death sentence and now has him working as security for Heaven's Tower.
Jim turned Ricalna into a mother keeper after he was shot by Syal. She doesn't care for him arguing with her but appreciates him helping out Syal.
Jim kicked Adam from Heaven's Tower.
