Being the representative of the micro student body, Mai is an advocate for tinies' rights, and she's known in the whole school for loudly asking for respect in the corridors every morning. Because the school is mostly made of people who hardly care about the quality of life of their smaller counterparts, most are annoyed by her sermons, though they're rarely outspoken about it because, in the end, they simply don't care about what's going on below their ankles.
Because of her activities, Bunny, Nana, Alice and many other characters know her very well, though most of them generally try to stay uninvolved in all of her fights for more rights since they ultimately don't care enough to openly start supporting and helping her.
She likes singing (more like shouting); she strongly dislikes people who disrespect micros, and micros themselves who don't stand up for their own rights.
Relationship with normal-sized people
She doesn't necessarily hate the bigger students, though she's aware that the majority of them won't care in the slightest about micros and their well-being, which has resulted in her acting bitter towards them most of the time.
Her spirit has been crushed hugely after Alice threatened to undress her and forced her to go against her own ideals once, though it seems that she's slowly getting back into action after that one incident; she was also later toyed with by Alice's bully friend who pretended to step on her after killing some of her supporters in order to discourage her from installing security cameras in the shool.
Relationship with micro-sized people
Mai's friends betray her when it's clear they could be killed for supporting her.
Being a micro herself, and being the representative of the micro students body, she's very respected by her own kind, and many tiny students will ask her for help whenever they find themselves in trouble while at school; very few of them actively help her in her campaign against the constant bullying that take place in the building every single day, which results in her being fundamentally alone in her battle despite every small kid more or less supporting her: and even when they do support her, they'll quickly their their back on her.
Mai and her senpai.
One micro person she particularly respected, her senpai who was also the former representative of the micro students at Mai's school, was brutally killed in front of her own eyes because a normal-sized student, a first-year girl, taped her to the floor, which led her to be stepped on by a third girl soon after. Because of this, she acquired the will to fight for the rights of those like her.
