Mio

An aspiring inventor with an already very impressive list of accomplishments under her name. Mio may be very smart, but she contrasts this by instead failing at the most mundane things, like remembering people's names. She claims her inventions are for the good of mankind, but often contradicts this very statement, implying the complete opposite during conversation at times.

Spoiler

Her real name is Morishita Narumi (森下 成海).
