Mikan has fair skin and long, choppy, dark plum purple hair that is cut unevenly as a result of bullying. The longest point of her hair appears to be just past her fingertips, whereas the shortest point is slightly above her neck. Her bangs flow straight down, but are also cut at visibly differing levels. She has pale gray-mauve eyes that almost constantly convey anxiety or tearfulness. There is a beauty mark under her left eye's corner.
