We're preferably looking for someone who can also sing because the Ending is sung by her voice actress in Japanese.

Being raised in a sheltered life, Mimi comes off as prissy, spoiled and selfish. Underneath it all, she is actually a very sweet, purehearted and caring person, who is sensitive to the feelings of others and dislikes fighting. Mimi is also honest, sometimes brutally honest to the point where she unintentionally hurts others. She is very ditzy, and has a rather wild imagination. Through her adventures in the Digital World, she learns that sometimes fighting is necessary to protect the ones she loves, and becomes more confident and resilient.
