Mukuro Ikusaba

Mukuro Ikusaba, the Ultimate Soldier, member of Class 78 and member of Ultimate Despair. She would later go onto help her younger sister Junko destroy the world by starting "The Biggest, Most Awful, Most Tragic Event in Human History" after which she was **** into a killing game along with her classmates while she was disguised as Junko.

She is quiet, cool and collected most of the time due to her military training, however, around her classmates and her sister, she turns from a cold-blooded killer to a relatively normal school girl.

What could possibly happen to such a reserved and calm girl that would leave her exposed?

Does her sister try to embarrass her? Does her trying to befriend her classmates end with her being put on display? Or does a day in the town with her friends prove to be too much for her?
