Mikan has light tangerine colored hair. Her hair length is up to her shoulders. She has fair skin and has lime colored eyes. To the left of her hair, she has a bun and the rest of her hair flowing down. A small part of her bangs on her left and her right stand up, two in particular. Her bun is held by a green ribbon. Mikan's hairstyle somewhat resembles Yoshiko Tsushima's from the anime Love Live.
Mikan is a reliable girl. When she first meets Yuko Yoshida in Episode 8, Mikan tells her that she can rely on Mikan like a big sister. Although, this wasn't taken nicely, since Mikan thought Yuko was younger than her.
Mikan is shown to be a Tsundere. If someone praises her for something, she will be flustered and she will reject the statement like "It's not like saying that will bring you any good!".
Despite having told Momo to bow down to her and thank her, Mikan is very attentive about Momo, especially now that she is in a weak state. She also adores Momo, shown in Episode 8 as she is enthusiastically telling Yuko how cute it was that Momo used to do a twirling pose as she is transforming.
- Because of a past incident, Mikan has a curse of when she is too excited or nervous, she will cause misfortune to someone she is acquainted with.
- Despite bringing misfortune, Momo doesn't seem to mind being around Mikan.

- Mikan once lived in Sakuragaoka City.
- Her family is quite wealthy, owning a factory of a processed food company.
- When Mikan and her family lived in Sakuragaoka, there was a time where their company didn't do well. Her father summons a demon to bind a contract with it to save the company, but this resulted in Mikan getting cursed.
- Sakura Chiyoda is the Magical Girl who resolved the demon incident, this is why she feels indebted to Sakura even if some of her curse effects still remain.
- After this incident, she and her family move to another town and built another factory company.
- A few years after Mikan and her family moved out, there was another incident that occured in the abandoned factory. This time, Sakura and Yuko's father Joshua solved it together, but this resulted in the factory becoming obliterated and was the reason Joshua was sealed into a tangerine box.
- The tangerine box that Joshua was sealed in is one of Mikan's family's factory production.
