On one occasion, she also has a job in teaching the students with their training practices in the Moon Demon Company. She appears willing to follow just about any order Guren gives her like jokingly attacking Goshi under his command whenever he goofs off. On the other hand, she has an unrequited crush on Guren and would accidentally confessed to him by the end of volume 2 of Guren's light novels, but he turn her down.
