Sister Ivry

Sister Ivry is a machine part of the Four Shining Stars. Her power, Heal Atomizer, is a Healing Ether ability that allows her to mend wounds, undo negative status effects, and repair living machines. Sister is short tempered, enjoys teasing, and has a laid-back attitude, but she is also dutiful and can be friendly to her allies. She has a sadistic side and enjoys torture. She dislikes things that can't be healed.

Sister is shown to be someone who cannot accept death as a finality for machines, going as far to believe machines can be brought back by using the cloud's stored data.
