Danganronpa 2: Goodbye Despair featured all of the surviving students from the first game.
The game says that the correct answer is true, however this is false. There are 3 survivors that do not appear in Danganronpa 2; Aoi Asahina ( Aoi Asahina | Danganronpa Wiki | Fandom ), Toko Fukawa ( Toko Fukawa | Danganronpa Wiki | Fandom ), and Yasuhiro Hagakure ( Yasuhiro Hagakure | Danganronpa Wiki | Fandom ). Browsing any of these fandom wiki pages will confirm that neither of them appear in the second game, yet are survivors of the first game. Toko’s page even contains the following excerpt:
Danganronpa 2: Goodbye Despair
Toko doesn’t appear in this game, having remained in Towa city with Komaru after the events of Danganronpa Another Episode: Ultra Despair Girls."
