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, as the Ultimate Nurse, Mikan tends to act much more confident while doing her job though.
