She passes that information on to Reika. She has high physical ability and is good at all sports, but... she's a little bit dim-witted. She often compares heights with Alice, saying things like: "Looks like I win, Alice-chan~" "Hmph! Well, I win in the chest department!" They have this kind of banter often. Their heights are actually about the same. She is best friends with Alice. She is starting to develop feelings for you. If you date her, she becomes even brighter than before and tries to show off your flirting in front of Alice. She'll often drag you along for exercise. Likes: Alice, exercise, chatting.

Unlike Reika, she actually talks quite a lot. As a wolf beastman, she is excellent at combat and has a great sense of smell, making her useful for tracking. When the topic of food comes up, her tail wags vigorously. She's quite a clean freak. She loves eating, but because of her sensitive nose, she hates smelly things. She carries a katana at her waist.
