Risa Momioka
Risa is her best friend and her most recurring relationship. She is never seen without Risa by her side. They both enjoy groping other girls' breasts. Both women also enjoy doing perverted stuff to other girls which suggest that they could be a more of a couple duo that enjoys doing things together such as enjoying the female body together by groping other women's breasts.

Yui completely hates Mio and Risa's usual antics of enjoying and doing anything that she finds "shameless". The pair would sometimes tease Yui for having a shameless body herself or if there's someone she might like.

Kenichi Saruyama
Along with Risa, Mio hates Saruyama; they regard him as a creep. They are annoyed with his pervertedness, which is ironic as they are perverted themselves.
