A sharp tongued and overly confident girl, Miu stands out as the loud and boastful inventor that loves to portray herself as a genius to the other students. She's constantly insulting people that come up and talk to her, as well as giving them insulting nicknames and looking down at others as if they're nothing but scum to her. However, that personality of hers quickly dies out when someone makes a remark back to her vulgar insults, which makes her become extremely defensive of herself. All in all, she's a two sided girl that can be difficult to control.

Miu's voice is a bit higher than mid tone, and with her energy a slight boastful tone needs to be incorporated into it.
