Yūki acts like the "old fox" type character, sometimes manipulating the other club members to get things done. She also acts like an old man that prefers to take things easy (in contrast to the younger members' enthusiasm).

Although she appears to be half trolling them sometimes, She doesn't look to care too much about looks or fashion and talks with a heavy local accent like an old man.
