In October 2016, a spin-off "sound" visual novel, entitled Kirigiri Sou, was quietly released by Spike Chunsoft.[5] A stand-alone sequel to the events of Danganronpa Kirigiri, Takekuni Kitayama revealed that he had been hired to develop the game (his first video game project, and a crossover with Otogirisō) due to the widespread success of the first three volumes of his novel series in Japan.[4]

Danganronpa Kirigiri was nominated for the "Best Entertainment Novel" category at the 2017 Sugoi Japan Awards, ultimately losing to Your Name.[6][8] In December 2022, Game Rant lauded the series as one of the best light novel adaptations of video games, complimenting the series' "dedicated fanbase [for] releasing amazing fan translations that are well worth tracking down".[3]
