Monokuma, the de-facto mascot of Danganronpa has a family who appeared in different games featuring him, so here are his family members...
The Monokubs, whom are Monokuma's self proclaimed children, serve as the secondary antagonists of Danganronpa V3 under Tsumugi's control. Each of them were killed during the executions. After the trial during Chapter 5, they came back to life as spares. During the trial of Chapter 6, they were blown up by Monokuma's detonator.
She is the only sister of all the Kubs. She loves flowers, but doesn't like anything gory.
