Hajime Hinata is the main character of Danganronpa 2. He finds himself transported to Jabberwock Island with the rest of his class from Hope's Peak Academy, but unlike them he cannot remember his own Ultimate talent.
Later revealed to be a member of the Hope's Peak Academy "Reserve Class" who only got into the school because his family had enough money to bypass the Ultimate talent portion. As a result, he was chosen for a scientific experiment to make a copy of Izuru Kamukura, the Ultimate True Hope, by modifying his brain. However, he fell in with the Remnants of Despair and was the only member of the Reserve Class who didn't commit suicide from Junko's influence.
At the end of the game, it's implied that Hajime was able to retain at least some of his memories from his time inside the game world, working with the other survivors to try and find a way to revive their comatose friends.
