An aristocrat of the esteemed Schwarzlang family, Mimi travels throughout Arland to spread her family's name. She is proud of both her family name and her nobility. Mimi has polished her skills throughout the years, and is now a determined adventurer. She aims to beat any fellow adventurers that are better than her.

Not much is known about Mimi's past despite being from a noble family. It's known that she doesn't have a siblings and that her mother died when she was very young. She doesn't show or control her emotions well, and this often reflects in her quick temper. Because of this, the only true friend that Mimi's ever had is Totori, who she thinks highly of, even if she doesn't admit it.
