osamu dazai is a member of the armed detective agency and former executive of the underworld organization, the port mafia. he has the ability named no longer human. dazai is a young man with mildly wavy, short, dark brown hair and narrow dark brown eyes. his bangs frame his face, while some are gathered at the center of his forehead. he is quite tall and slim in terms of physique. for his attire, dazai wears a black trench coat that reached under his knees. he also wears bandages over his right eye and his right arm is in a sling—presumably products of his suicidal pastimes. at some point, he was able to regain the use of his right arm. dazai is a mysterious person, his true intentions are never revealed unless he reveals them. the person who got closest to the truth of his personality, as acknowledged by dazai himself, was his friend sakunosuke oda, who recognized that dazai shall linger in the darkness forever, as there was nearly nothing that can surpass his mind. regardless whether he is on the side of killing people or saving them, oda knew that no place in the world could fill dazai's loneliness, which oda thought dazai knew in himself. dazai as the youngest executive in mafia history. in addition, dazai kept an enigmatic and dark façade, whose endeavors in the mafia were unrivaled and eventually earned him the status as the youngest leader in the history of the mafia. because of his aptitude despite his youth, dazai contributed to about half the mafia's profits for at least two years. eventually, dazai's ledger became tainted; ichiyō higuchi describes his blood to be "dark as the mafia itself". even in his adulthood when he becomes an agency member, when kyōka izumi showed remorse over having killed 35 people, dazai remarked with a sinister face that such number is nothing. as a saying in the mafia went, "the greatest misfortune for dazai's enemies is that they are dazai's enemies", for dazai was aptly described to be "practically born to be in the mafia". he was extremely confident and was a terrific planner, coming up with long-run strategies to subdue his enemies. for instance, he was able to lure mimic operatives, who were previously trained soldiers, to fall under his trap. dazai is quite skilled in persuasion notably through his words, which he appeared to utilize in interrogations that broke targets who did not divulge anything under kōyō ozaki's torture squad. behind this grim persona, dazai admitted that he joined the mafia to be exposed to death, violence, and people giving in to their urges and desires, expecting that—in this way—he would be able to see the inner nature of humankind firsthand in hopes of finding a reason to live. following oda's demise, dazai defected from the mafia and went underground in order to heed oda's final request for him to "be on the side that saves people". admittedly, he reckoned that people change over time where potential surfaces, which apparently seems to apply to himself as well. upon joining the agency, dazai is usually called lazy, with doppo kunikida always scolding him for being unproductive and slacking off. despite that, he has shown a sharp wit, deducing all the unlikely situations that led atsushi nakajima to believe he was being stalked by a tiger when he was the tiger in question. he has complete confidence no matter what type of situation he is dealing with, be it combat or simply bad situations he formulated in the first place. dazai after eating a weird mushroom dazai eats a hallucinogenic mushroom. in most occasions, dazai is overly dramatic. he takes most of his actions as a joke, and, although they are very well-thought plans, he does not credit himself for most of what he has done. dazai likes to tease anyone and everyone, especially if it means that he can get a laugh out of it. as a suicide maniac, he often attempts to commit suicide in comical manners, but he oftentimes fails or gives up on it when such methods are painful. dazai's typical approach to invite a woman in to join him in a double suicide. dazai, in particular, wishes to commit double suicide with a beautiful woman; though he admits that he "likes all types of women", he possibly prefers the type who would die with him if he asked to. kunikida once wondered why dazai is quite popular with women and called him a menace to women, a sentiment chūya nakahara once used when he threatened to leak dazai's address to every woman he ever made cry, which dazai soon asked him not to do. dazai also once had a run-in with a bomb threat instigated by a woman whom dazai figured was obsessed with him. while his suicidal tendencies are initially comedic, they reveal a truly dark deep hole that dazai has. even as a teenage boy, dazai questioned whether there was any value in life. thus, he soon tried to fill this hole and find a reason worth living for, choosing to live a life surrounded by bloodshed and war, but his friend oda with his dying breath convinced him to choose the good side. he understood that even though good and evil mean little to dazai, he may become a slightly better person if he were to choose well. in the past, while he was still suicidal, it was shown to be far less comedic. he even described the death as a way to free himself from the oxidizing world, but, strangely enough, he could not die no matter how hard he tried. additionally, he was extremely brutal and methodical, setting up traps to catch captives alive to torture them for information, and he would often beat his then apprentice ryūnosuke akutagawa for disobeying orders and to push him to the limits to improve his abilities. dazai allows suspicions to surround and frame him in order to outmaneuver the azure apostle. while in the present he is more lighthearted and comical, he still retains some of his darker personality. he is still able and proficient at coming up with long-run strategies, though he doesn't inform his teammates what they are until the time is right. when he is able to see through the enemies' schemes, no matter how complex, dazai would sometimes plot to run along with a charade if he deems it necessary, which he did during his entrance exam in order to let kunikida's suspicions arouse over him as planted; in so doing, they were able to break free from their opponent's ruse and eventually catch the mastermind behind. dazai is also willing to use dirty means to achieve his goals, such as purposely deflating ango sakaguchi's car seat airbag when they crashed so ango would get injured and force him to cooperate with dazai for pardoning kyōka in exchange for having his wounds healed. nonetheless, he does care for his teammates and watches out for them, especially atsushi for whom he sees the greatest potential. moreover, dazai develops a sense of duty and utilizes his wit and intelligence to the agency in their quest to help maintain yokohama's peace and order. as part of his various plans and well-calculated strategies, he even devised for atsushi and akutagawa to collaborate at times to become a new generation of twin dark who could take on the brewing evil lurking within the city. no longer human allows dazai to nullify others' abilities on contact. it relies on skin contact and is always active. as such, he can nullify any ability even while restrained as soon as it touches him. intelligence: dazai's intelligence is his primary source of expertise as a mafia executive in the past and as a detective at present. ōgai mori, a proficient tactician himself, widely trusted and relied on dazai's intelligence, whom he claimed to be his most worthy right-hand man should he have stayed in the mafia. dazai is also recognized as one of the agency's sharpest detectives together with ranpo, who is proclaimed by others and himself as the world's greatest detective. with his intelligence, he is able to go head-to-head against the formidable fyodor dostoevsky, an avatar of cunning who sees dazai to be quite identical to him. even ranpo once subtly admitted that going up against fyodor is like going up against dazai, whom the great detective himself views to be quite an enigma even as his co-worker. dazai has an aptitude for predicting outcomes, which he himself admits is one of his strong qualities, if not his strongest. negotiation skills: dazai is an adept persuader, able to negotiate with others and consequently acquire his required outcomes. he is able to convince kōyō, a mafia executive, into letting kyōka get arrested and even to stay in the agency as their captive; francis scott key fitzgerald, a former enemy, into collaborating with him to catch fyodor; and even akutagawa into tailing and potentially helping atsushi—the latter's sworn rival—before the outbreak of the decay of the angel' terrorism plot. he also once presumably persuaded naomi tanizaki to work with him behind her brother's back, who both were secretly tasked by kunikida into tricking dazai, only for this scheme to backfire once dazai realizes their clandestine arrangement. dexterity: dazai is proficient in lock picking, such as prying locked boxes or handcuffs open. moreover, he was able to implant a bug in higuchi's pocket without being noticed by the mafioso. he was also able to swipe chūya nakahara's knife without even being seen. kunikida also once described dazai to be "frighteningly dexterous", knowing that dazai can pick a lock to a bank's safe with a needle or easily switch out slips of paper with fake ones. physical prowess: dazai had fair-to-middling hand-to-hand skills among the mafia as chūya recalled, which his nullification ability made up for. dazai was able to briefly hold his own against chūya, the most physically gifted in the mafia, by predicting and defending against his moves and timing which he had memorized, though he got backed up on the wall soon after. dazai was also able to fend against a big man by utilizing his resources around him, albeit being overwhelmed later on. heart rate manipulation: using the device that monitors his vitals which is planted on him at meursault, dazai can vary his heart rate at will and digitize his messages in order to communicate to the outside world. during his time as a mafia executive, dazai held a record of 138 counts of conspiracy to murder, 312 counts of extortion, and 625 counts of assorted fraud, among other crimes. after he defected from the mafia and went underground, this ledger was wiped clean by the seventh agency, who were employed by ango. (to sakunosuke oda) "for most things in life, it's harder to succeed than fail. wouldn't you agree? that's why i should attempt suicide rather than commit it! committing suicide is difficult, but it should be relatively easier to fail at attempting suicide!" (to sakunosuke oda when asked how he got his injuries) "i was walking and reading a book called how to not get hurt out of the blue and fell into a drainage ditch. i was speeding around a mountain path and drove off the cliff. iwas trying to kill myself by slamming my head into the corner of a block of tofu." (to ango sakaguchi and sakunosuke oda) "who wouldn't want to keep a relationship's fire burning? sounds wonderful if you ask me." (to ango sakaguchi and sakunosuke oda) "i always lose the things i don't want to lose the most. that's why i don't feel anything anymore. the moment you get your hands on something worth going after, you lose it. that's just how things are. there is nothing worth pursuing at the cost of prolonging a life of suffering." (to sakunosuke oda) "hey, odasaku, do you know why i joined the mafia? i joined the mafia because of an expectation i had. i thought if i was close to death and violence—close to people giving in to their urges and desires, then i would be able to see the inner nature of humankind up close. i thought if i did that.. i would be able to find something—a reason to live." (to sakunosuke oda) "you're such an idiot, odasaku. the biggest idiot i know. you didn't have to do this. you didn't have to die." (to ōgai mori) "you were afraid, weren't you, mori-san? afraid i'd cut out your windpipe and assume the boss' seat. just as you did to the last boss." (to fyodor dostoevsky) "you said that we were two peas in a pod. you're right, but there's one key difference. ..it's true that all of mankind is sinful and foolish. but what's wrong with that?" (to fyodor dostoevsky) "you don't really understand god one bit, do you? "perfection and harmony"? god doesn't give a single care about those. i've seen it so many times.. his gimmicks are the accidental and the illogical. that's.. a weakness you and i both have. we thought of thousands of ingenious schemes, and we still ended up in here.. in a prison at the ends of the earth. the ones who actually make the world turn.. are those who scream within the storm of uncertainty and run with flowing blood." etymology the name "osamu" is a given name. the surname "dazai" means "thick" (ta/da) and "rule" (zai). according to 1st official guidebook: what are you strengths and weaknesses? "i only have strengths." who is your ideal partner? "someone who i can commit suicide with." what do you want now? "sake." what is your motto? "a clean, bright, and cheerful suicide." the most you’ve ever thought you were going to die "never." according to 2nd official guidebook: how do you spend your free time? "nothing." what time do you sleep and wake up? "irregular, but i don't sleep much." how do you feel about teaming up with chūya again? "thinking of new ways to annoy him if by some chance i have no choice but to team up with him again." in regards to suicide methods, dazai have tried the following: slamming his head into the corner of a block of tofu death by poisoning: mushrooms asphyxiation compressed death in a drum cardiac arrest dazai is very bad at driving. dazai seems to be unable to sleep if it is not completely dark. in general, chuuya comes off as an irritable and arrogant character, especially around dazai, his ex co-worker at the port mafia. he frequently smirks while in combat and is the type to criticize his opponents during combat. chuuya is quite short with a petite, yet muscular build. he has grey eyes, and striking orange hair that frames his face, with a longer section that falls just past his left shoulder. he wears a black hat with a red hatband and a thin silver chain that hangs over the brim. his outfit consists of a white button-up shirt under a dark red vest, a black choker, a black ribbon bolo tie held together with a small silver buckle, an open black cropped jacket with the sleeves rolled up at the elbows, black slacks, a black belt hanging off his right hip and black low-arch shoes. he is almost always seen wearing black gloves. chuuya also sports a long black coat with light-colored lining and lapels that he wears around his shoulders like a cape. the undercoat is a light shade of red. in the past, he wore a short black pea coat over his hoodie. he also wore black pants and brown shoes. a bracelet could also be seen on his right wrist. on the surface, chuuya is a temperamental and rather arrogant, blunt man. he revels in fighting, happy to show off his combative ability, and taking great pride in his reputation as the mafia's strongest martial artist. taunting remarks pair with his pride, as he isn't above ridiculing his opponents in the middle of a fight. befitting of an executive, he has no qualms eliminating the port mafia's enemies by any means necessary, including murder, however, isn't nearly as homicidal in his tactics as members such as ryunosuke akutagawa and the members of black lizard tend to be. for as hot-headed as he may seem, chuuya isn't impossible to reason with. in fact, he's rather reasonable when no one is pushing his buttons. while his skills and presence signal an inherent threat, he's reliable enough for mori to assign him the task of confronting the armed detective agency during the three-way conflict involving the guild. it's true he didn't hesitate to retaliate and fight back against akiko yosano and kenji miyazawa. in fact, he takes great pleasure fighting against people that put up a good fight, but as soon as yukichi fukuzawa addresses him for more information, chuuya disengages from the battle. here as well, his nature as a mafioso shines through, expressing no remorse for the danger the mafia intentionally put naomi tanizaki and hirako in, using them as bait. in fact, he's rather smug about it, knowing it angers the angers immensely. ruthless as he is, chuuya seldom takes people's lives for granted and knows the importance of compromise and rationality. he refrains from unnecessarily brutal methods when need-be, and has enough sense to know when enough's enough. notable instances include his conflict with arthur rimbaud, the man responsible for attempting to kill him long before he joined the port mafia at age fifteen. chuuya fully intended to kill him, but heard rimbaud's last words without malice nor mockery. in fact, rimbaud's final words for him had a deep effect on chuuya's own outlook on life and himself. He receives rimbaud's hat as an entry gift to the port mafia and takes good care of the hat as a result. after osamu dazai "mercy killed" an enemy, only to repeatedly shoot and laugh at the corpse, chuuya demanded he stops, seeing no sense in dazai's actions. chuuya's grudge against ango dakaguchi does not stop him from acknowledging the fact he owes the man a favor, and as such refrains from antagonizing ango. and, by extension, his subordinate mizuki tsujimura until he can repay his debt. just as chuuya took his responsibility defending sheep's well-being from their enemies, this holds true for his loyalty and devotion to port mafia after joining. so as reasonable as he may be, his top priority is port mafia's prosperity and well-being, thus nothing will stop him from fulfilling his responsibilities as an executive even at the cost of other's lives. fierce in his loyalties, chuuya finds betrayal intolerable and treats his subordinates quite well. in the past, chuuya struggled greatly with his identity and place in humanity. his connection to arahabaki ended in him questioning how human he truly was, worsened by not knowing the truth behind why he was freed from the government's possession in the first place. while his strength lies in his ability, the awareness of a god's effects on him left him feeling as though he wouldn't feel worried nor fear in a fight, knowing he'd most likely win without a scratch. he attributed this to being — in his mind — inhuman, and thus unable to understand the depth of such emotions. in order to give himself a sense of restraint, he preferred kicking largely over throwing fists, never even removing his gloves. he figured if he came to a fight where he had to remove his gloves, it was because he could no longer enjoy the rush of a battle, and genuinely needed to defend himself — in other words feeling an attachment to the life he lived, even if he felt like a foreign soul in a shell, rather than a human being. this holds true to the present, as chuuya's only seen removing his gloves when using corruption in dire moments. after rimbaud elaborated his own beliefs on humanity, chuuya had a bit of a change of heart, taking his own life a bit more seriously. the sheep's betrayal affected him greatly, alongside port mafia's direct involvement in uncovering the truth of his origins, but ultimately led to his loyalty in them. the drive for learning more about himself contributed largely to his rise in rank, much faster than anticipated. chuuya's ultimate downfall is his intense disdain and hatred for dazai. the two never got along, with chuuya instantly hating dazai's underhanded, warped strategic personality. dazai has always gone out of his way to dehumanize and ridicule chuuya, constantly attacking his pride and even driving sheep to abandon and betray him in the past. even now, the slightest insult from dazai will set chuuya off on a tangent, taking full advantage of his quick temper and pride. this makes it easy to distract chuuya from tasks at hand. nonetheless, as part of twin dark's nature, chuuya acknowledges dazai's role as the tactician, extending minimal trust in at least knowing that dazai knows how to effectively overcome a situation.
