Theresa

Theresa is a demi-human mercenary who was originally a human Seeker, but transformed into a lizard-like demi-human after perishing in a labyrinth. She always wears a lizard mask that obscures her face, revealing only her long black hair and a tail. Because of her demi-human status, she was undervalued at the mercenary guild until the protagonist, Arihito, recognized her potential and welcomed her as his first companion. Although she is mute and seemingly expressionless, she possesses a strong-willed, loyal nature and gradually shows her feelings through subtle gestures and the color changes of her mask. In battle, she fights as a nimble 'Rogue' on the frontlines, utilizing her dual-wielding abilities and shields. Strengthened by Arihito's exceptional 'Rearguard' support, she becomes a reliable shield for her allies while harboring a deep sense of devotion and affection toward him.
