He is one of the sixteen participants of the Killing School Semester. Kokichi Oma is the secondary antagonist in the videogame Danganronpa V3: Killing Harmony, serving as a obstacle for both Chapter 4 and Chapter 5. V3 has shitload of amazing sprites that I prefer over any DR1 or 2 sprites so special mention goes to most of Ouma sprites and also.
