Kokichi Oma is the Ultimate Supreme Leader in Danganronpa V3: Killing Harmony, released in 2017 by Spike Chunsoft. His distinctive nihehe laugh became one of his most quoted voice lines because it signals his love of lies and mind games throughout the trial chapters. Clips of the laugh spread through YouTube edits, TikTok cosplays and anime soundboards, where fans isolated it from longer voice line compilations. It remains popular because a single giggle instantly identifies the character and his unpredictable, trollish personality without needing any dialogue context.
