An Shiraishi

An has amber eyes and long, waist-length black hair with blue tips, worn loose with little star accessories. She takes out her earrings and star accessories during school. Her voice is strong and radiant.

An is a cool and candid girl with an unyielding spirit. She acts very affectionate towards her close friends, and is very kind and forgiving. She leaves a strong impression on others and is hard to forget. An encourages those around her to be the best they can. However, her and Akito often bicker due to their long-standing rivalry.

When An is part of the disciplinary committee at Kamiyama, she gets nervous when asking someone to follow the rules, getting shaky and stuttering when asking someone to tuck in their shirt.
