Mikan Tsumiki

Mikan is an extremely meek, paranoid and fragile individual who suffers from hazardously low self-esteem as a result of severe abuse and bullying. This has resulted in many behavioral symptoms such as being easily intimidated, breaking down and crying with little provocation, profusely apologizing and nervously stuttering while speaking. She constantly worries about annoying, boring or offending others, going so far as asking Hajime Hinata if it would be alright for her to remember his name when introducing herself. This delicate persona makes her a natural target for Hiyoko Saionji's predatory and cruel personality. However, as the Ultimate Nurse, Mikan tends to act much more confident while doing her job, and she is knowledgeable and intelligent. Her medical knowledge proves to be useful in murders, as she provides autopsy reports, including information on the corpse's state, details on injuries, cause of death, and time of death. Furthermore, she sometimes gives (often unwanted) health advice to others concerning things like eating and sleeping, and may occasionally start to describe things like bodily functions in way too much detail in her wish to give the other students' information on the subject at hand. Unlike most students, Mikan has even mentioned that she likes being on Jabberwock Island, because her classmates acknowledge her and her talent makes her useful.

Mikan has fair skin and long, choppy, dark, plum-colored 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.

She wears a nurse uniform which consists of a pale pink short-sleeved shirt with a white collar and puffed sleeves trimmed with white. A short, pale blue, slightly wrinkled pleated skirt is visible underneath. Mikan wears a white apron over this which is tied behind her neck with a ribbon. It is marked with two red lines on the left side of the apron, one going down to her middle and another short red line perpendicular to the vertical one in a simple design. As well as this, she has bandages wrapped around her left forearm and hand, excluding the fingers, and around her right leg from her mid-thigh to above her ankle. Additionally, she has a square gauze band-aid on her left kneecap and wears pale pink crew length socks and white loafers.
