Avelin Nina ニーナ・アヴェリン

She is a foreign student at St. Union, originally from Russia, and was recruited by Miyuki to join the Circlet Bout club. She is very stoic and laconic, often preferring to be alone. Spends most of her free time playing FPS online games where she excels in sniping. This skill translates to Circle Bout where, even though she's the designated backup and barely gets to play, she uses a sniper rifle as her weapon since she is more adept in taking down opponents from a distance.
