I have no association with the projects: Danganronpa and Danganronpa Rebirth Voices; this is fanmade.
Makoto Utsuki kills Mitsunari Kog but it's a bit unclear what happens for the execution:
Either Mikoto and Monodora are executed (due to the motive) or Ayumu Fujimori and Mikoto get executed (Ayumi lives though)
The text vaguely translates to "Itsuki san and Fujimori kun has been selected as the blackened"
