Mukuro Ikusaba

Mukuro Ikusaba (戦刃 むくろ Ikusaba Mukuro) is one of the characters in Dangan Ronpa: Academy of Hope and High School Students of Despair, but has a more prominent role in the prequel novel, Dangan Ronpa/Zero, and the other novel, Dangan Ronpa IF. She has the title Super High-School Level Soldier (超高校級の「軍人」Chō Kōkō Kyū no "Gunjin"). She is the mysterious "16th student" and the older twin sister of Junko Enoshima.

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

Personality
Despite being an incredible soldier, Ikusaba is very out-of-touch with her own emotions and only knows how to take orders from Enoshima. 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 Ikusaba and sometimes even believes Enoshima'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 Enoshima 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 Enoshima had written for her, Ikusaba 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.

Ikusaba saw herself as Enoshima'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
Ikusaba was involved in Fenrir before entering Hope's Peak Academy. She was in the 78th class of it and became classmates with Makoto Naegi and some others. Around the events of Dangan Ronpa/Zero, she saved Naegi from Isshiki Madarai, and Naegi held her with high regard because he was saved by Ikusaba a lot; which parallels Naegi's kindness towards her in Dangan Ronpa IF. Though, around the time in the Dangan Ronpa/Zero novel, she was acting as Junko Enoshima when she was talking to Ryouko Otonashi.

High School Life of Mutual Killing
Ikusaba (disguised as Enoshima) was executed by Monobear during Chapter 1, which led to the other students to believe that Enoshima 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.
