Mimi's known for her overly soft personality and the way she acts, she's very clumsy and often finds herself tripping into the cold snow of Elurra. She loves anything fluffy and often finds herself roaming around the town with her Kimono or her coat when it's night time season; she'd use her normal attire without the coat when it's daytime season. She has a lot of insecurities and tends to overimagine the silliest things possible. Although she's an airhead, she often can become very smart in situations where she knows and has the capability to do it. Even then, Mimi is very kind and tends to wish wellness over her friends and herself, heck, even a stranger. She also likes to explore a lot and be super curious of most things, she's bashful and often becomes a very talkative person with whoever she trusts.

Mimi was born almost two decades ago in the cold town of Elurra, located at the northernmost part of the Aster continent; her mother, a very soft, caring, selfless and strong person, and her father, very strict and stubborn, but caring and compassionate raised her for 17 years with love and care, however, she had a restriction of going outside, this restriction was made by her father, due to him losing his sister thanks to the humans who were on the outskirts of the town, he feared the same thing would happen to her and didn't want the humans to take her away like how they did with her sister. Mimi never really knew what was like to be outside, however, she went outside when there was any festivity going on, however, she was always with her parents, without any exception.

Mimi received her first blessing at age 8, an arctic hare blessing, she assisted Vaughn's school to learn how to use her magic properly, she had problems with it at first, but managed to learn and use her magic properly. With it, she decided to connect more with her blessing, allowing her to gain more trust with it and being able to make her hare ears floppy and also turning them bigger.

While these events happened, Mimi's mother taught her what was called "her legacy", she taught her many baking recipes and how to use the tailoring tools she no longer used due to her age. She constantly kept learning and improving her skills until age 18, where she decided to talk with her parents about moving and opening a bakery in the most central part of the town, her father disagreed due to his fear, but Mimi was able to convince him thanks to her mother and her dreams.

Her story starts when she moves out of home, she tries to locate herself somewhere nearby to places of interest and a home where to reside, luckily enough, she finds a perfect place near Yume's workstation, little did she know about the town, so it wasn't that easy to localize herself into it. When she was able to find a place where to reside, due to Elurra's trading system, she had the possibility to snag a comfy place for a good "price". Months passed, and she opened her bakery not too far away from home, and relatively close to places of interest.

After a couple of months working, she decides to pack her stuff and set a goal for herself to visit most towns in Aster and being able to spread her recipes to those towns so they could be able to try them out and make them as well, however, due to her anxiety, it was difficult for her to part to the different towns as her decisions mixed up often and didn't let her make a choice. A week passed after that, and she decided to gain more confidence with herself and part away to a good quantity of towns, starting with Laoluzia, in where she'd reunite with Vanché, her childhood friend whom didn't see for about 6 and a half years. During her trip, she befriended lots of Annies, shared her recipes, met Annies interested in her fashion and viceversa, with that, she learnt to improve herself and her anxiety lowered down by significant amounts.

In December, close to Elurra's new year's festival, most of her friends visited Mimi from far away towns to celebrate the holidays and her birthday with her, with it, upon a wish for wealth, she obtained her second blessing, a moon orchid.

Mimi since then, although she can't visit her friends regularly, due to the strict rules of not leaving town, she spends most of her time going outside and receiving her friends who come from very far away to visit her. Mimi may not be the best person, but she has improved over time, and that's what most of her friends are proud of.
