It was another day in the trans-void while stars 1 and 2 were in charge of eliminating the angels who committed a small error; 3 went to guard the border and saw the alternate universes, and their curiosity awakened.

Characters
✨
Lia/3LiaCustomizable
Originally a star without feelings or emotions, created to maintain order and execute rule-breakers. She escaped the Trans-void to the AUs, followed by a demon who became her friend. Together they explored, and she gained a physical body—no longer a 4-pointed floating star. She has a name but still struggles to understand emotions, attempting to imitate them. Her human form has long brown hair with white tips, eyes of the same color with a thin 4-pointed star in the center, and pale skin.
⚪
2Star 2Customizable
The second of three sisters. Calm but emotionless, she shows slightly more affection toward 3. She judges with the death penalty and appears as a floating white ball of light.
🌟
3Star 3
The eldest of the three stars. She judges all angels with the death penalty for the slightest mistake. She is extremely strict, cruel, and devoid of emotion. She appears as a floating 9-pointed star without a physical body.
😈
RodrickCustomizable
A demon who once saw one of the stars cross the border. Driven by curiosity, he followed her and eventually became her friend. Though he knows she lacks feelings, he fell in love with her. He appears as a tall, athletic human with blond hair, green eyes, and wings that turn his eyes red when he uses his powers.
