She is the superior of Aya Shameimaru, Hatate Himekaidou, and Momiji Inubashiri; she has a strong, mutually cautious relationship with Aya as a superior and a journalist. While she gives orders to Momiji as a boss, she dislikes putting subordinates in danger and sometimes takes the front lines herself. She receives appropriate respect from the Tengu, including Hatate. Her influence is such that she can command mountain Youkai outside Tengu society, though some do not obey.
