A close friend of Yuri, Miyu is often there to support Yuri when she needs someone to talk to about her horrid duties. Since she seems to often be cheerful and hopeful, she is a good friend to Yuri. She has her best interests at heart, and if Yuri is feeling down she'll try and cheer her up by inviting her out and showing her a good time to help her forget her troubles, at least for awhile.
