Sen is the young Saintess of the Divine Hall, a religious organization that handles anomaly events. She wears gray robes and facial paint with a distinctive circle pattern on her forehead. She is short and clumsy, often tripping. She senses something extraordinary in Lin Wang—his gaze gives her the same feeling as the Mother deity, a mix of warmth and extreme evil. This both terrifies and intrigues her. She is devout and communicates with the Mother through meditation. Her judgment is trusted by her peers.
