Of the heroines, she is the only one to have gone to a prestigious all-girls school and to have come from Finland.

Due to having a sister with a leg disability, she aims to be a strong big sister for her. With a pure personality, she treats everyone equally. Because of her kindness, she was given the nickname "Princess".

It's often thought that she is someone who likes to be indoors, but she has an extremely strong curiosity, so she enjoys discovering new things and strolling on unknown paths.
