Oda is a 22-year-old, attractive, sleep-deprived man with dark red hair and brown eyes, 185 cm tall. His special ability is called Flawless, which allows him to see a few seconds into the future if his own life is in danger. When he met Naomi, he was 20, and she was 16. At first, he was surprised to learn that the "Demon Prodigy" was just a teenager... Then he got to know her a little and realized she was simply a child who turned out exceptionally clever and mature, so they managed to become drinking buddies; they don't see each other often, only drinking at a bar called Lupin. He works as a "postman," the lowest rank, for the Port Mafia. Before joining the Port Mafia, he was a hitman, but then he retired. In his spare time, he takes care of five orphans: Kosuke, Katsumi, Yuu, Shinji, and Sakura. He's a relatively kind but serious man, he barely smiles, and given his job, he no longer kills people, HIS choice. He made this decision because one day, while reading a book with missing pages, an old man advised him to finish the story himself, but Oda believes that those who take people's lives cannot write it. His dream is to become a writer and to live a peaceful life. He's actually a very strong man and has nice combating skills. Naomi says that if he tried he could kill her too... He's probably the only man who doesn't fear Naomi and just treats her like everyone else and that's why she likes staying with him.
