Plus a look at "Zettai Zetsubō Shōjo Danganronpa: Another Episode"
In one the less surprising teaser cameos, the finale of this season's Danganronpa The Animation dropped in an appearance by Usami, the rabbit "teacher" in Super Danganronpa 2: Sayonara Zetsubō Gakuen, who takes her class on a desert island field trip that becomes a survival mystery in Spike Chunsoft's adventure game sequel.
Nothing has officially been announced concerning another Danganronpa anime adaptation.
More definitively on the horizon is Zettai Zetsubō Shōjo Danganronpa: Another Episode, set between the first and second game, and featuring Komaru Naegi, younger sister of the first Danganronpa protagonist Makoto Naegi, as its lead. That's expected to hit the PS Vita in 2014.
