As a kitsune and youkai, she's very mischievous, including in her roles as Guuji and owner of Yae Publishing House. She couples this mischievous streak with impressive skills of manipulation and reading people. As such, her tricks and pranks are usually elaborate, long-winded affairs towards rather simple ends, which she does out of enjoyment and the fact that she enjoys watching people squirm. This has caused many people, such as Thoma and Gorou, to become easily terrified upon seeing her.
