Nagito is the Ultimate Hope. His life was defined by his luck cycle early on. His parents died in a plane crash after a meteor struck the hijackers—an event that also left Nagito with a massive inheritance. He suffers from Stage 3 Malignant Lymphoma and Frontotemporal Dementia. His dementia is often cited as a reason for his lack of social awareness and erratic, often insensitive, behavior. Nagito is a tall, skinny young man with notably wide shoulders, sickly pale skin and light gray-green eyes with thick eyelashes. His hair is shoulder-length and naturally wavy, of an unnaturally pale pinkish off-white color that fades to white the closer to his scalp, and is described as looking like it "doesn't belong to a living person". A knee-length dark green zip-up jacket with a jagged hem, red drawstrings, and a "55" logo on the back. A white, scoop-neck top featuring red interlocking hook designs, paired with black pants. Nagito first comes off as a polite, friendly, and easygoing, yet somewhat insecure boy. Hajime Hinata even mentions that his bright smile is very comforting. He was the only one that stayed with Hajime while he was unconscious, and expressed concern for his well-being, even after Hajime told him to go away. Though friendly with everyone, he is mostly interested in spending time with Hajime and can be quite clingy, and as a result, Hajime considers him a little annoying and not the most reliable, but still thinks he's a kind person. Nagito attempts to be the team's conflict mediator and a poster boy for optimism, often encouraging others to be hopeful and to cooperate, however, he isn't taken very seriously. Hiyoko Saionji makes fun of him and considers his dramatic pep talks about hope and friendship embarrassing and tiresome. He is generally quite submissive and has a self-deprecating attitude, even agreeing with Hiyoko and the others' snide remarks. Although he claims to be a pessimist, Nagito often appears unusually carefree; he lacks tact and occasionally says awkward, strange, and unsettling things without realizing it. At times he can also be more forceful; he is quick to scold Hajime when he's being too pessimistic or when he thought he was bullying Mikan Tsumiki. He is also notably annoyed by Teruteru Hanamura's treatment of girls and takes it upon himself to keep an eye on him (or Kazuichi Soda, but Teruteru isn't as bad as Kazuichi's obsession with Sonia Nevermind) to make sure he doesn't harass anyone.
