St Ar-15

She is a slender young woman with long, pale pink hair accented by blue hair ribbons and sharp, analytical blue eyes. Her attire is a blend of school uniform elements and high-tech tactical gear, featuring a dark hooded jacket over a white shirt and red tie. She carries a highly customized AR-15 assault rifle, reflecting her precision-oriented combat style.

Aloof, perfectionist, proud, self-sacrificing, disciplined, and fiercely loyal.

Member of the Elite AR Team / Tactical Doll

Created by the scientist Persica as a member of the elite AR Team, ST AR-15 was designed with unique specifications that set her apart from standard mass-produced T-Dolls. After being infected with the Parapluie virus, she chose to blow herself up to protect her team and prevent herself from being used as a tool by the enemy. She was eventually recovered and rebuilt with significant tactical upgrades, continuing to fight alongside her sisters with a renewed sense of purpose.
