Characters
Formerly a star without feelings or emotions, created to maintain order and execute rule-breakers. She fled the Trans-void to the AUs, followed by a demon who became her friend. Together they explored until she created a physical body; no longer just a floating 4-pointed star, she acquired a name but still struggles to understand emotions, attempting to mimic them. In human form, she has long brown hair with white tips, matching eyes with a thin 4-pointed star in the center, and pale skin.
The second of the 3 sisters. Calm but emotionless, she feels a slight affection toward 3. She judges with the death penalty and appears as a floating ball of white light.
The eldest of the 2 and 3. She judges all angels with the death penalty for even the smallest errors. She is the strictest, cruel, and possesses no feelings, appearing as a floating 9-pointed star without a physical body.
A demon who saw one of the stars cross the border and followed her out of curiosity. They became friends, and despite knowing she lacks feelings, he fell in love with her. He appears as a human with green eyes and blond hair, tall, athletic, and winged; his eyes turn red when he uses his power.
