Амано Сораха

An excellent Lily with a combat power based on high physical ability, Soraha has a bright and cheerful personality. At the end of her first year, Chika Takekoshi, who belongs to the legendary Legion of Yurigaoka, "Alveheim", was dismissed and the Legion was disbanded. Being Chika's best friend, Soraha also effectively retired from being a Lily. Before she was about to leave, she met Kusumi Egawa in a special dormitory. While spending time with Kusumi, she changed her mind and chose to stay at Yurigaoka.
