Ōgai Mori

Ōgai Mori (森 鴎外,) is the Boss of the Port Mafia.

Appearance
Mori is a forty-year-old man, with a fairly tall and slender physique. His eyes are violet, and befitting of a mafia boss, almost always completely dark and devoid of light. He has straight, chin-length black hair slicked back, leaving bangs on each side of his face.

Normally, he wears a sharp suit, consisting of a white button-up, a black pinstriped suit jacket, black shoes, and black trousers. The shirt has a purple and white striped tie. Over this, he wears a black trench coat and long, almost knee-length maroon scarf he leaves hanging over his shoulders untied. He also wears white gloves.

In public, Mori wears much less lavish attire, more typical of a "doctor". He wears a purple button-up shirt, black tie, black trousers, black shoes, and a long white coat. Furthermore, he leaves his hair loose, and two strands fall over his forehead.

Personality
While initially showing himself as an ordinary, clumsy and worried old man, he later shows more about his true character, keeping calm even when the other people trapped in Anne's room ran away, staying together with Atsushi and Tanizaki, and still maintaining his composure when the latter was captured.

Mori later reveals that not only is he good with strategies and planning, but also a cruel and merciless person capable of infusing fear on his enemies. However, his cruelty is not for cruelty's sake. Mori always weights the gains and losses of his decisions, choosing the most optimial solutions for the Port Mafia as a whole. Consequently, these decisions leave a bloodstained path, and have hurt and traumatised countless other people, especially Akiko Yosano and Osamu Dazai. Mori never takes emotions into full account, the epitome of logical thinking and strategy. That said, his intelligence allows him to manipulat and abusee many people by appealing to their needs and wants. Emotional manipulation and abuse have gotten Mori far in his motives at the cost of many lives, and by the time someone's realised they've been used, it's often too late for them to turn back. To Mori, a 'heart' only gets in the way of war, a belief leading to his irredeemable actions of using Yosano's ability and mentally breaking her during the Great War.

While a largely logical person who knows how to use words to his advantage, Mori is not above threats and intimidation typical of a cold, experienced mafioso. Age and gender do not matter to Mori, but when it comes to his grander schemes, he has a history of manipulating children, as their inexperience makes it that much easier to control them.

Mori's use of manners and polite conduct mostly attribute to maintaining a sense of control and power in any situation. For the most part, acting like a 'normal' person makes those around him less wary, as when he's in public and needs to avoid suspicion. Otherwise, it creates a certain distance between him and others, as if nothing they say ever fazes him. Yukichi Fukuzawa, his former ally, knows the depths of Mori's darkness, and he and Dazai are most often the ones to see straight through Mori's many pretences. Once this facade disappears, Mori's intensity and willingness to do anything, even kill, become apparent and unsettling. His intensity is so much so that Lucy Maud Montgomery is paralysed with fear when Mori confronts her.

He does treat his subordinates with respect, valuing their skills and contributions to the organisation and acknowledging their power. As such, even when facing a certain degree of insubordination, Mori is willing to overlook some mistakes so long as the outcome benefits ''the Port Mafia. ''This contributes to why he never punishes Ryunosuke Akutagawa's rash behaviour. Even then, according to Mori, "effort is what matters, results come second", in the face of Akutagawa's previous failure of capturing Atsushi Nakajima.

This aligns with Mori's leeway towards the organisation's most active, powerful members, allowing them a certain degree of 'freedom' and independence from his tight scrutiny. Generally, he usually only regularly speaks with his two most active executives, Kōyō Ozaki and Chūya Nakahara, the former of which often the first to criticise Mori's eccentrics in the form of dry banter. He and Kōyō converse the most often, and their partnership leads to Mori agreeing to spare Kyōka after she defects. As a result of the Port Mafia's prosperous control in Yokohama, Mori enjoys being held in high regard, either by respect, fear, or a mix of both, by his many subordinates.

Mori views the position of an organisation's leader as both ruling them and being their slave. This belief drives Mori to his drastic and ruthless strategies. Furthermore, he is more than happy to use a common enemy to his advantage, as when revealing Naomi Tanizaki and Kirako Haruno's hideout to the Guild in hopes of using the Agency to take care of them and alleviate the Port Mafia's own workload. He uses the same tactic when leaking the orphans' location to André Gide, getting the orphans slaughtered and driving Odasaku to his own suicide mission. In both cases, Mori makes it so his direct word never reaches its intended target, leaving the power of his actions to force their hand instead. This manipulation and usage of knowledge is the core of Mori's decision-making and tactics, making him a dangerous for.

Losses and failure are Mori's worst enemies, such as a large number of subordinates and racketed collaborations dying during the Q incident, or Kōyō's being held at the Armed Detective Agency. Likewise, he detests "parasites" such as smugglers and the ilk, people he believes they suck Yokohama dry for their own gain and upset its delicate balance. Given Mori's respect for Soseki Natsume, Mori agreed to keep balance in Yokohama, and Mori takes this seriously. For as cruel and cold Mori is, it's unmistakable that he's vital to Yokohama's balance.

The only time Mori's acknowledged a major oversight in his decisions is when taking in and mentoring Dazai. He largely underestimated Dazai's own intelligence and shrewd, detached way of looking at the world. Ironically, their near-identical nature unsettled Mori. Nonetheless, Mori takes his mistake and moulds it into a valuable discovery: a subordinate and right-hand that knew his way of rationalising. Control over Dazai was crucial to Mori, considering Dazai's intelligence could one day be his undoing. This largely contributes to Mori's decision to use Sakunosuke Oda, a dear friend of Dazai, in eliminating Mimic and driving Dazai to defect.

Truly, the only person privy to Mori's less menacing and controlling side is Elise, even though there's incredible irony in the fact that even Elise's demanding, harsh attitude against him is something he intentionally configured. Mori has an obsessive nature towards Elise, irritating her with excessive trips to dress shops, tailors, and the like just to dress her up for his own amusement. Much to Elise's exasperation, even her harsh nature is something Mori enjoys. Given that Vita Sexualis manifests as a form of Mori's desires, it's unfortunate to note that he's a self-admitted paedophile, something both Elise and Fukuzawa have expressed great disgust in, the latter considering Vita Sexualis a disgusting and disturbing ability.

Ability
His ability, Vita Sexualis (ヰタ・セクスアリス,), is an ability that allows Mori to summon and 'configure' Elise's personality in any way he wills; he can make her levitate, chase after an enemy at high speed, and make her save him no matter what. He can summon Elise at will and make her attack his enemies with a barrage of large medical equipment.

Elise has shown her displeasure in Mori's ability in which she stated he always gets to "set the scene" and make all the decisions. Although Elise is powerful, Vita Sexualis requires strength and energy, thus when infected by Alexander Pushkin's virus, summoning Elise takes a toll on Elise. When Fukuzawa cut her down, she disappears. As Mori's ability, Elise doesn't die, but it takes time and energy for Mori to resummon her.

An important detail to note is that Elise used to be more subservient and borderline emotionless as Mori's ability. However, sometime after Yosano's mental breakdown, Mori intentionally configured Elise to mimic the young Yosano's defiant personality, showing a deep-seated obsession towards Yosano, of whom whose stubborn nature Mori frequently fawned over during the Great War.

Background
Mori previously ran an underground clinic, neutral ground for all in the criminal world to use to their benefit. Although a group once attempted to kidnap him, they were killed by both Yukichi Fukuzawa, a bodyguard at the time, and Mori, whose blood lust came in full swing.

At an unspecified period of time, Natsume Soseki developed a connection with both Fukuzawa and Mori.

After joining the Port Mafia eight years before Osamu Dazai defected, Mori killed the former leader of the Mafia. He told Dazai, fourteen at the time, that the story was that the former boss declared Mori his successor. .

Dazai Osamu and The Dark Era
Mori calls on Sakunosuke Oda to find Ango Sakaguchi after the latter disappeared the previous night, not even reaching his place of residence. He tells Oda that Ango, being an intelligence officer, is holding information about the Mafia that would crush them if he were to sell it to other organizations—but even if that weren't the case, Mori says that he wants to save Ango if something had happened to him because Ango is his competent and important subordinate. He then issues Oda with the Silver Oracle as proof that Oda is acting his orders, the Boss of the Port Mafia, thus granting Oda the right to order anyone in the Mafia around, even the executives, to assist him in his task.

Ultimately, Odasaku dies in the struggle against Mimic, shot down by Gide and in turn killing Gide. Dazai understands that Odasaku was used by Mori in a plan to gain a Special Abilities Licence as long as Mimic was defeated. Resenting Mori's usage of Odasaku, and being the one responsible for the orphans' location being leaked to Mimic, Dazai denounces any obedience and loyalty to the mafia from that point on. After he defected, however, Mori kept his seat as an Executive reserved.

Plot
Mori first appears questioning Higuchi about her and Akutagawa's continued service after their failure to capture Atsuchi, although his face is hidden.

He later makes a full appearance while looking for Elise in the streets. When Lucy activates her ability, he is trapped in Anne's Room along with Atsushi Nakajima, Jun'ichirou Tanizaki, and the rest of the people on the street. In front of Atsushi and Lucy, he initially plays the innocent doctor. After Tanizaki gets 'caught' by Anne and thrown through the black door, Mori advises Atsushi on the game theory and how to approach the problem. After Lucy's defeat he returns to the port mafia and declares that they will annihilate the Agency as well as the Guild.

Quotes

 * (To Dazai) "The Boss... died of a serious illness. His dying wish was to have me succeed him as the next Boss. And you were the witness, understood?"
 * "The Detective Agency and the Port Mafia. If the government higher-ups catch word... that the heads of the two largest Ability organizations in Yokohama are having a secret meeting, they will definitely be foaming at the mouth."
 * "Till next time, Dazai-kun. The invitation to resuming your duties as an Executive member in the Mafia still stands."

Trivia

 * There is a great gap between Mori's concept and the work chosen for his ability. Vita Sexualis deals more with the protagonist's 'discovery' of his own sexuality, but no paedophilic content involved.  The only similar thing is that the love interest of The Dancing Girl, Elise, is roughly 16 or 17, whilst the protagonist is an adult man.  As for his author counterpart, Mori was indeed a military surgeon respected his logical and direct nature, being a respected figure in Japanese history and even being involved in criticisms of censorship, but the real Mori was never a paedophile.
 * Being a strategist, he has read many works concerning game theory and war tactics, and is an expert on the topic.
 * Elise's name originates from the authors The Dancing Girl, where a Japanese man living in Europe means a young woman named Elise.
 * Elise calls him "Rintaro", which is the author Mori Ōgai's real name. It is possible this is Mori's real name as well.
 * His preferred weapon is a scalpel.
 * The author joined the military in order to study medicine, rising in rank to a head surgeon, reflecting the mafia boss' previous occupation as an underground doctor.
 * In the anime, he appears next to Chūya in a building where a reception desk sports a logo resembling an M with the words "Mori Corporation" beneath. This is likely a shell company of the Port Mafia..
