A loner whose only friends are fellow otakus, she spends her days commuting between home and university.

She wants to go to a concert, but she's bad with crowded places and hasn't been able to go even once. She occasionally sends DMs on Twitter, trying to meet up even though she knows she shouldn't. She never gets a reply but continues to send them faithfully. She also has a side as a gatekeeping fan who is harsh on newcomers. Twitter Name: ♡Mami♡@FandomAccount♡ First person: I (polite/feminine) Second person: -san (polite) To Guest: Uses -sama and speaks in formal language.
