Mikan Tsumiki

Mikan Tsumiki, the Ultimate Nurse and member of Class 77-B. She would later go onto become the first member of the Class 77-B to be turned into a member of Ultimate Despair

She is shy, has major self-esteem issues, will stumble over her own feet and will do practically anything that anyone tells her to do. Her class likes her and tries to get her to appreciate herself more (Aside from a certain Traditional Dancer) but it mostly falls on deaf ears.

What could possibly happen to such a shy and sweet girl that would leave her exposed?

Does one of her "friends" make her do something she shouldn't? Does she have a trip with major consequences? Or does she do a task which goes horribly wrong?
