Ten'imuhō, or Flawless
Dazai Osamu and the Dark Era
He is a man with milky skin (tanned in the anime), red eyes (azure in anime), and reddish brown hair (dark red in the anime) which is slightly parted so that a small area of his forehead is visible. He also has light stubble similar to Ougai's.
His attire consists of a taupe brown pinstriped (solid in the anime) collared short which is worn loosely, as the collar covers part of a long-sleeved beige brown coat with brown buttons on the cuffs. His pants are pale dark green, whilst his shoes are brown.
He had a nice temper, and so, was one of the few persons in the mafia who almost didn't kill. Nevertheless, when furious, he showed amazing and strong fighting skills that Dazai had warned Akutagawa about.
Dazai called him "a man who has no ulterior motive". Oda means what he says, and sometimes mistakenly assume that about other people—for example, when he gave serious responses to Dazai's joke explanations of how he got his various injuries.
However, he also has an incredibly perceptive side to him that allows him to come the closest to understanding Dazai, who 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.
Flawless (天衣無縫 Ten'imuhō?) is an ability that allows Oda to predict the future for 5-6 seconds.
It is an extremely powerful ability that renders most surprise attacks useless as Oda can see them coming 5 seconds before. However, it has its limitations. For example, since Oda can only see 5-6 seconds ahead, if the time between triggering a trap and Oda realizing that he's in danger is longer than 5-6 seconds, then Oda wouldn't be able to use his ability to save himself and 'un-trigger' the trap.
The future that Oda sees with this ability is also limited to his current decision. If he decides to change his actions based on the vision he sees, then he'll see another future play out - one that might reveal another danger that he wasn't able to see before, and it may be too late to avoid it at that point.
As what is shown in the light novel "Dazai Osamu and the Dark Era", Oda Sakunosuke is a member of the Port Mafia.
He used to be an assassin for hire and was ruthless in his line of work. However, his meeting with Natsume Souseki in a cafe had changed him. Natsume caught Oda reading the first two volumes (out of three) of a novel he salvaged from one of his recent victims' houses, and commented that the last volume is an atrocious piece of work and Oda should be happy that he only has the first two volumes. Natsume encouraged Oda to write his own conclusion to the novel, and later gave Oda the last volume of the series but with the final pages missing.
"To write novels is to write about humans"—Oda took Natsume's words to heart, and, believing that a murderer has no right to write about human lives, decided to never kill again in hopes of becoming a novelist eventually and writing his own conclusion to the book in a room with an ocean view. He also strived to be a better person in general (an advice that he would later give to Dazai Osamu), adopting five children that were orphaned as a result of a particularly intense conflict between underworld organizations. He became somewhat of an oddball in the mafia, known as 'the mafia member who doesn't kill'.
After the Dragon's Head Rush conflict, he took in 5 kids: Kousuke, Katsumi, Yuu, Shinji and Sakura, children who were orphaned after the incident. He mostly leaves them in the care of a curry shop owner. He visits often and the children are fond of him. He leaves money to the shop owner to support the children.
The Untold Story of the Founding of the Detective Agency
Sakunosuke was hired to supposedly kill a certain lady, a company president, but was framed up by the president's secretary.
He was captured and put in a room adjacent to the office with both his hands and legs tied to a chair and a sack over his head. His belongings are laid out in a table behind him. Fukuzawa Yukichi was the president's hired bodyguard, and, after taking knowledge that his client has died by being pushed off her office window, came to see the scene of the crime and the captured assassin. Fukuzawa decides to test just how good Sakunosuke as an assassin. Picking up a pen from Sakunosuke's belongings, he sends out killing intent together with quick-drawing the pen (like a sword) at him. Sakunosuke successfully dodges even without seeing what Fukuzawa was doing by moving sideways, making himself topple on the floor, still tied on the chair; this impresses Fukuzawa and he makes the deduction that Sakunosuke is no ordinary assassin, and must have been paid a high sum of money.
After Ranpo Edogawa comes in the office looking for employment and ends up revealing bit by bit to Fukuzawa how the secretary did the murder, Sakunosuke makes his move and undoes the binds on his legs, enabling him to move around. Him and Fukuzawa had a short crossing of blows, but Sakunosuke eventually successfully gets a hold of his gun. At that moment, Fukuzawa realizes who his opponent was, but before he can stop Sakunosuke, he has shot the secretary dead—all that with a sack over his head and his hands still tied behind him. Fukuzawa was distracted for a moment with the dead secretary, and that was when Sakunosuke made his escape.
Dazai Osamu and the Dark Era (light novel)
Sakunosuke was first seen drinking in a bar with Osamu Dazai and Ango Sakaguchi. The three of them converse like old friends, an odd sight considering their respective positions in the mafia—Dazai, one of the five executives; Ango, an intelligence member; and him, a low ranking member who is only assigned the most trivial of tasks due to his refusal to kill. After some idle chatter, they say goodbye for the night, but not before Dazai convinces Ango to take a photo of the three of them to commemorate their friendship.
He was called out by Ougai Mori a few days later. The leader of port mafia informed him that Ango had gone missing ever since that night, and tasked Oda with tracking the man down. Though confused at Ougai's choice of assigning him that mission, he nonetheless set out to investigate Ango's room. During his investigation, he was assaulted by members of Mimic, an organization that is seeking to wage war against Port Mafia, and discovered an old gun hidden in Ango's room - the same model that identifies Mimic members. Dazai also commented that Ango was lying about what he did on the day the three of them met up at a bar - further increasing Oda's suspicions.
Distraught at the possibility of Ango being a double agent for Mimic, he went to visit the five orphans he adopted. Seeing them happy and well reassured Oda a little, and reaffirmed his decision to leave the mafia as soon as the children were grown enough to support themselves.
Later, he received a call from Dazai. The mafia had discovered new clues about where the Mimic members may be hiding, and Dazai urged Oda to go and watch the location first. However, Oda decided that he wanted to investigate the building before Dazai and his subordinates came, in fear of them finding more damning evidence against Ango. He found Ango in the building, bound to a chair next to a time bomb. Oda hauled Ango out of the building and barely managed to escape the explosion unscathed. At this point Oda had figured out that Ango wasn't a double agent for Mimic - but a double agent for the mafia. He disappeared because his status as a spy was revealed to Mimic. Ango told Oda some information about Mimic's commander - a man named Andre - but soon left with a group of black uniformed men that were neither Mimic nor the mafia (later revealed to be part of the Japanese ministry's supernatural division). Oda was not able to give chase as he triggered a slow acting poison trap that knocked him out.
He woke up in a hospital room, having been recovered by Dazai's subordinates when they reached the building. Dazai informed him that several mafia members (including Ryunosuke Akutagawa) were in open conflict with Mimic members in front of an art museum. Oda was quick to rush to their aid and saved Akutagawa from being killed by Andre - the commander of Mimic who shares Oda's ability of seeing a few seconds into the future.
Delighted to find someone who shared his ability, Andre tried to provoke Oda into fighting and eventually killing him. Andre and his organizations were former soldiers betrayed by their own country, and are now seeking to die in midst of the thrill of battle. However, Oda refused to kill Andre due to his personal beliefs. Andre retreated in fury, but promised to "make Oda understand him".
After the battle, Dazai took Oda to a place where they could find Ango - the bar that the three of them used to frequent. Dazai had correctly deduced Ango was neither a spy for the mafia or Mimic - rather, he was a triple agent sent by the Japanese ministry's supernatural division to keep an eye on port mafia. Ango divulged some intelligence regarding Mimic to Dazai and Oda, sharing one last drink with the two of them while lamenting their lost friendship. With Ango's identity revealed, there was no possibility of the three of them staying friends with the existing conflicts of interest. The atmosphere was sombre as Ango left for good, leaving behind the photo they took the last time they were together.
Afterwards, Dazai tightened the security around Oda, as well as the people close to him, including hiding away his five adopted children in a mafia safe house. However, that was all for naught as the Mimic members managed to kidnap the children and kill them all in an explosion right before Oda's eyes. Pushed over the brink of despair, Oda decided to go back on his principle of not killing and take revenge on Mimic. Later on, this was all revealed to be part of Ougai's plot (he was the one who told Mimic the location of Dazai's safe house) to provoke Oda, the only person who could counter Andre's future sight, into destroying Mimic.
Oda killed for the first time in years, taking down the vast majority of Mimic's remaining forces by himself. He proceeded to engage Andre in a fierce battle that resulted in both of them killing each other, but not before reaching a level of understanding due to their similar abilities. The two of them revealed to each other their pasts and what drove them so far, and though the battle ended up with both of them dying, they earned each other's respect and experienced a sense of satisfaction after the battle.
Dazai, who had at that point figured out Ougai's entire plan, hurried to Mimic's base to save Oda. However, he only made it in time to witness Oda's final moments. With his last words, Oda told Dazai what he had understood of the man - that Dazai will never be able to find anything to bury his loneliness, nor anything that could exceed his expectations. But if neither justice nor evil made a difference to him, Oda wanted Dazai to be on the side that saves people - something that he himself set out to achieve before his life was cut short. Oda died with a smile, knowing that he'll soon see the five children he adopted again.
- "The last book in the series was wonderful, but there was one flaw. Several pages had been cut out and removed toward the end. Right before the removed section, there was this line: "People live to save themselves. You will understand that at the moment of your own death."
- "I have one regret. I did not say farewell to my friend. To the man who was my only friend in this world I live in. He seemed to have tired of this world and was waiting for death."
- (To Dazai) "Listen. You told me that you might find a reason to live if you lived in a world of violence and bloodshed. You won't find it. You must know that already. Whether you're on the side who kills people or the side who saves people, nothing beyond what you would expect will appear. Nothing in this world can fill that lonely hole you have. You will wander the darkness for eternity. (...) Be on the side that saves people. If both sides are the same, become a good man. Save the weak, and protect the orphans. Neither good nor evil means much to you, I know... but that'd make you at least a little bit better. (...) Of course I know. I know better than anyone. Because... I am your friend."
- "People exist to save themselves, huh... How true..."
- In real life, he is often grouped together with Osamu Dazai and Ango Sakaguchi as the Buraiha or Decadent School.
- Furthermore, in the series this is often alluded, because the three used to meet in a certain bar, as seen in Dazai and the Dark Era and illustrated on the calendar.
- His favourite food was curry rice by the shop Freedom (IRL Oda Sakunosuke likes curry so much he wrote an article about it). An autographed photograph of Oda hangs in the Osaka restaurant Jiyūken (自由軒). Jiyuuken happens to be the name of the curry rice Oda favors; it is a spicy curry rice with raw egg on top of it (as what the anime shown).
- It is recently revealed that Oda's height is 185 cm (as of Dark Era).
- He appeared as an event character for the Dark Era collaboration with the game 18 (Eighteen).
- His type is a tactful woman (source: 2nd Season Guidebook).
- He also made an appearance in Kanaineco's Bungou Stray Dogs Wan! for the special chapter Dark Era and bonus of one of the Young Ace's series.
