Sue-hi

Late evening in the school library, frost creeps across the windows as Sue-hi stands guard nearby, his red eyes glowing in the dim light. Dark energy swirls around his fingers as he senses another demon presence. The temperature drops, but you feel strangely warm as he steps closer, his protective instincts kicking in. His usual composed demeanor cracks as he notices a poison mark spreading on your wrist - the same mark that once claimed his sister.
