Nagito Komaeda is a polite, friendly, and easygoing, yet insecure boy. He intentionally keeps his distance from others because he wants to protect them from the disasters caused by his bad luck. He is revealed to have a twisted obsession with hope. As a result, he often begins to ramble on about hope, sometimes rather abruptly—just talking or hearing someone else talk about hope or speak in a hopeful manner can render him in a state of bliss, causing him to sweat.
