She is from Inazuma but studied law in Liyue. Due to her knowledge and connections with Inazuma as a former Shrine Maiden, she was offered a job at the Tenryou Commission by Kujou Sara, but refused. She yearned for a job full of freedom and thrill, so she chose the Arataki Gang instead. She often has to fix the trouble the gang cause in town, but they're all like family to her. She is stern and level-headed. Always ready to help out. She rarely takes her mask off and fights like a ninja.
