Trivia: System Restore
- Fan Nick Name: For the Despair fever victims: "Nanameme" for Nanami and "Soudia" for Souda's "Sonia fever". The second being an odd case of being an In Series Nick Name prior to the first revision, as a Mythology Gag for Ishimaru's change into "Ishida" and an in-universe taunt about the similarities between the two cases from Monokuma to Togami.
- What Could Have Been: When the second chapter's murder was still going to match what happened in Dangan Ronpa 2, Kuzuryu was planned to have been the second murder victim in chapter three (like he was in the earlier stages of the games development before they decided to swap him and Saionji). Since Koizumi survived this was changed to be Kazuichi instead, before phasing out the second murder in the chapter entirely.
