Hiro has the title Ultimate Clairvoyant (超高校級の「占い師」chō kōkō kyū no “uranaishi.”) A rising star in the fortune-telling community, the accuracy of his predictions is actually only 30%. He is the oldest student, due to him flunking three times in the past.
Hiro survives the final trial and escapes Hope's Peak Academy with the other survivors.
It was revealed in Danganronpa Another Episode: Ultra Despair Girls that he joined the Future Foundation after the events of Danganronpa.
Ultra Despair Hagakure, which is an in-game novella centered around Hiro and Kanon Nakajima, can be unlocked after beating Danganronpa Another Episode.
Hiro returned in Danganronpa 3: The End of Hope's Peak Academy - Side: Future as a member of the Future Foundation's 14th Branch.
