Mikie is a naive and clumsy girl who often gets excited over little things. She likes to fantasize about Origami as she has grown fond of her. Due to an occasion where Origami saved her from an unrestrained Tohka, she developed a great admiration towards her and decided to join the AST. However, this also caused her to share the same opinion towards the Spirits as the rest of the AST, viewing them as a threat to the human society.
Mikie is also a determined and a hardworking girl who likes to open up her thoughts about the world. She also values friendship above all, which is the reason why she was moved by the story that Cecil had told her.
Mikie has brown hair and fashioned them in pigtails while letting some of her hair loose. She has a small frame body type that often mislead people to think she was younger than she really was.
Before the start of the series, Mikie was a happy kid and loved by her father, Okamine Torataro. When her father became a successful entrepreneur, they became distant to each other. Eventually, her father could not stand her presence anymore and banished her from the household. Mikie who became depressed and feeling suicidal, deliberately ignored the spacequake alarm. Much to her surprise, Mikie was attacked by then untamed Tohka. But thanks to Origami's intervention, she was unharmed. That was when Mikie developed a huge admiration for Origami that motivated her to become an AST wizard. However, due to her not recognizing Tohka after being sealed by Shido, Mikie ironically befriended her.
The next day after her enrollment, an explosion occurred near the Tengu city. Thinking that a Spirit appeared, Mikie hurried to the place only to find a young girl named Ashley Sinclair who claimed to "hunt" the members of the AST. Ashley expressed her excitement in finding a worthy opponent due to having some research done on the performances of several AST members in the past, only to be quickly disappointed after realizing Mikie was not as strong the reports claimed.
