There are many legends according to her appearance when, in fact, she is hiding her "true form." She was just enjoying scaring humans until she got bored of it, so she spent most her time underground until the incident in Subterranean Animism where she went above ground to check what happened. She found out that Murasa and the other youkai who were also sealed underground made it above ground and were planning something.
She decided to have some "fun" by putting the Seed of Non-identification in the fragments of Tobikura. Eventually, she saw the heroine collecting them and she decided to secretly follow them, either helping or getting in their way before deciding to show up to congratulate the heroine for saving Byakuren.
