Oda's ability, Flawless ( 天 ( てん ) 衣 ( い ) 無 ( む ) 縫 ( ほう ),, Ten'imuhō ?) allows Oda to predict 5-6 seconds into the future. However, he also had an incredibly perceptive side to him that allowed him to come the closest to understanding Dazai, whom he referred to as 'his dear friend, who had grown tired of the world and is simply waiting to die.' It is his understanding of Dazai's loneliness, as well as his regret of not being able to do anything about it, that prompted him to leave behind the last words that became the trigger for Dazai deserting the mafia in favor of carving a brighter path for himself, something that Oda wanted to do. Oda means what he says, and sometimes mistakenly assumes that about other people-for example, when he gave serious responses to Dazai's joke explanations of how he got his various injuries. Dazai called him 'a man who has no ulterior motive'. Nevertheless, when furious, he showed amazing and strong fighting skills that Dazai had warned Akutagawa about. He had a nice temper, and so, was one of the few persons in the mafia who seldom killed. Oda was a man described as kind, despite working for the mafia, by Dazai. Yukichi Fukuzawa also noted that his eyes were 'frighteningly vacant' and almost devoid of any emotion. He also wielded holsters where he kept two old pistols, his signature weapons during his assassination missions. In his younger years when he worked as an assassin, Oda once wore a navy collared shirt, work pants, and leather shoes. Oda also occasionally donned a bulletproof vest beneath his shirt, particularly during his combat-related endeavors.

His pants were pale grey, whilst his shoes were light brown. His attire consisted of a black-and-white pinstriped collared shirt that he wore loosely, whose collar covers part of a long-sleeved beige-brown Kevlar-woven coat with brown buttons on the cuffs. He also had light stubble similar to Ōgai Mori's. He was a tall man with dark brown eyes and short hair that had a reddish tinge and was slightly parted so that a small area of his forehead was visible.
