Mukuro Ikusaba

Mukuro Ikusaba (戦刃 むくろ Ikusaba Mukuro) is one of the characters in Dangan Ronpa, and has a more prominent role in the prequel novel, Dangan Ronpa/Zero. She is the mysterious "16th student" and the older twin sister of Junko Enoshima.

Appearance
Mukuro appears much like her sister Junko besides her short black bobbed hair, but there are some other differences. Mukuro's eyes are less round than Junko's and her breasts are smaller. She also has freckles across the bridge of her nose.

Personality
Despite being an incredible soldier Mukuro is very out-of-touch with her own emotions and only knows how to take orders from Junko. She craves for her sister's praise and acceptance and will do nearly anything to get it. Because of this she allows herself to be put-down by Junko and sometimes even believes Junko's insults, which are meant to be manipulating. She joined Super High School Level Despair because she had no interest in the world and only wanted to please Junko but after realizing her feelings for Naegi during Dangan Ronpa IF she found the courage to finally oppose her sister. Once she was no longer acting on the script Junko had written for her, Mukuro was almost apologetic in her behavior and has strong protective instincts towards her classmates, especially Naegi.

She is self-admittedly poor at negotiating with people and devising tactics.

Mukuro saw herself as Junko's weapon to spread despair before the events of Dangan Ronpa IF, but doesn't fully believe her younger sister's philosophy on despair.

Pre-Despair Incident
Mukuro was involved in Fenrir

High School Life of Mutual Killing
Mukuro (disguised as Junko) was executed by Monobear during Chapter 1, which led to the other students to believe that Junko was dead. Later, during Chapter 5, her dead body was reused by the mastermind to lead the other students into thinking that the unknown 16th student died. However, before they could take at closer look a the body, it exploded with a Monobear bomb and thus there wasn't much evidence left.
