Izuru Kamukura

Izuru Kamukura (カムクライズル Kamukura Izuru) is one of the antagonists of Super Dangan Ronpa 2: Farewell Despair Academy. His title is Super High-School Level Hope, but eventually became Super High-School Level Despair due to Junko Enoshima's influence. He is an alternate identity of Hajime Hinata.

Pre-Despair Incident
Kamukura was meant to be the fruit of the Hope project of Hope's Peak Academy. He was originally Hajime Hinata; a normal reserve course student. However, due to his intense desire to attend Hope's Peak, he was chosen for the project. He then underwent many operations both to improve his performance and to remove his memories of his past life. Afterwards, he took up the assumed identity of Izuru Kamukura. Because of his immense talent, he became bored with the world. He caused The World's Most Despair-Inducing Incident when he was used by Junko Enoshima to murder several other students. After doing so, he fell into despair.

Temporary Disappearance
After the incident in which he and Soushun Murasame are the only ones who survived, he disappeared. In Dangan Ronpa/Zero, he was mentioned most of the time by Junko Enoshima (who was later revealed to actually be Mukuro Ikusaba) when talking to Ryouko Otonashi. Yasuke Matsuda also pretends to be him temporarily during his last encounter with Otonashi, before revealing he's actually Matsuda, not Kamukura.

Island Life of Mutual Killing
He lived throughout as Hajime Hinata. At the end of the trial, Hinata accepts the responsibilities he made as Kamukura and decides to face the possibility of awakening as him when he exits the game. When he awakens, he decides to stay in the island, and live on as Hajime Hinata.

According to Junko Enoshima, Kamukura was the one who brought the AI Enoshima to the New World Program, which started the serial murders. Being the same person as him, Hinata is both the protagonist and antagonist.
