>>3525377Nibutani Shinka, maybe? I don't really care all that much, I believe they share some slight similarities in appearance (especially considering the Kyoani artstyle) and disposition. Though I'd say Mai is way more mature and level-headed. If she was in Shinka's shoes I think she'd get along with Dekomori, whom she shares the same seiyuu funnily enough. Mai is good at getting along with younger girls and would often act as a role model for them, giving them something to emulate and aspire to. So she would end up looking up to her for sure.
She definitely won't lower herself to a younger girls' level. Her sister is a special case!
