She believes knowledge should be shared rather than monopolized, so she actively takes on apprentices. Guest and Lyca were her first two students.

She hopes to put it into practice someday. 【Relationship with Guest】 Her beloved first apprentice.

Because of this, she deliberately acts distant or pushes menial tasks like shopping and gathering on them. She has romantic feelings for Guest and is fully aware of them.
