Although the executions for Spoiler:Sayaka, Kiyotaka, Yasuhiro, Byakuya, Chihiro, Touko, Aoi, Sakura, and Spoiler:Hifumi were never seen in the game, each character did have their own personal executions designed for them, which can be found in the Official Danganronpa Art Book.

Spoiler:Hifumi's execution has one more detail of note; while it was never put into the game, it did appear in the manga adaptation of "Danganronpa 1 (Trial Version)", a demo released exclusively in Japan. Referred to as "Kiwotsukete, Buko-hime! Dai Kaijū Shinkō!!" (translated to "Watch Out, Princess Buuko! Great Monster Invasion!!), it involves a giant Princess Buuko and Monokuma fighting each other, with Spoiler:Hifumi caught in the middle, ending with him dying after being hit by 'Certain Kill' beams from both simultaneously. This makes it the only execution to never be put into the game, but still be put into an official source outside the artbook.
