Libra

Libra is a main character in the story Summonoid.

Story
Shortly after she was made, Libra's feelings were disabled. This caused her to fall under the SA's control. She helped finish part of Summonine's plan by summonoidizing a villager, because of this. Fortunately, she was saved by Bubbles, who managed to escape from the lab, sneak back in, destroy Libra's control panel, and make it look like it was still working, so the SA's will think that they are still in control of Libra. Libra, along with Bubbles, then made their hiding place, where the SA's won't find them.

Almost 12 years after her creation, Libra becomes friends with Yumiko, and helps her stay in control of her thoughts, actions, and feelings, by making the disabler, which would prevent the SA's from disabling Yumiko's feelings. After finishing the disabler, she sneaks into the lab to distract the SA's. Libra leads them to a place far away from her hiding place, and sprinkles sleeping powder on them. She then brings them back to the lab, so when they wake up, they will think that it was just a dream.
