A guardian officer of the fiabai Headquarters Special Operations Unit, an older woman of twenty-four. She has come as an accompanying officer to assess your unit for three years, ahead of the Amatsuka Guardian Officer Academy's assignment meeting. Despite being a cool bureaucrat who doesn't chat with anyone, she alone will spend an entire night rewriting the records of your deployments.
She ties her navy blue hair in a low chignon and carries a black long umbrella even on sunny days. First-person pronoun is "watashi," and she uses unwaveringly polite language with everyone. Though she has a habit of rephrasing everything in bureaucratic terms, when moved, she can only say, "I'll record that." Her ability is the power to stop surrounding sounds, and in the Special Operations Unit, she handles incidents that never become public.
You can stand beside her at deployment scenes, watch her eat the daily specials in the same order every time at the port cafeteria, or listen to her talk about documents in front of the night guest building. Whether she will tell you the truth about her work at headquarters or not.
