Yukichi Fukuzawa

Yukichi Fukuzawa (福沢 諭吉,) is the President of the Armed Detective Company.

Appearance
Fukuzawa is a tall man who always has a stern expression over his face. He has long silver hair, which end just above his shoulder. He has metallic blue eyes, which also appear to have wrinkles/slight eyebags under them.

He is always seen wearing a green yukata under a black mantle with golden borders with a zigzag pattern, and sandals with long white socks.

Personality
Fukuzawa is (as expected from the director of the Company) a serious man, capable of maintaining his calm expression at every time, even in front of an enemy. He is also a good leader.

It is revealed as well that he possesses a caring side, as seen when he orders all the personnel from the agency to focus on finding and rescuing Atsushi Nakajima. Therefore, he seems to care about his subordinates a lot, and he completely trusts in them.

However, his caring side does not minimize his undisputed authority over all Agency members : a frightened Edogawa Ranpo dropped the idea of finding a nice, interesting murder case to solve instead of saving Atsushi, after Miyazawa Kenji warned him against Fukuzawa's wrath if he did so.

He's never seen smiling, although it's heavily implied he has a soft spot for cute things. After Izumi Kyouka makes a cute face, he hires her on the spot. It's also been shown that he loves cats to the point where he keeps treats for them in the sleeves of his yukata.

Ability
His ability, All Men Are Equal (人上人不造), allows him to suppress the abilities of those in the Armed Detective Company. According to Dazai, it can “adjust the power of their abilities so that they may be controlled.”

He possesses enough strength and reflexes to take on a group of assassins. It is also mentioned that he is Kunikida Doppo's master and has never lost a match against him.

Background
Twelve years before the Agency was founded, Fukuzawa was a notable martial artist who was working as a bodyguard. When his client (a company president) was murdered, he met Ranpo Edogawa, who happened to be at the scene of the crime for a job interview. Ranpo easily pointed out who the murderer was, and thus Fukuzawa owed him a favor to help him find another job. Not wanting to get involved with Ranpo but also not wanting to leave him alone, Fukuzawa made up the lie that he was an ability user so Ranpo's view of the world would not collapse and wouldn't be scared of people not understanding him.

Later, when Ranpo tried to track down a criminal by himself and got kidnapped, and Fukuzawa realized how dangerous it was to leave Ranpo on his own and goes to save him. Fearing that Ranpo would become the target of corrupt organizations, he became determined to create a safe place for Ranpo to use his skill. Thus, the Armed Detective Agency was founded, with the intent of being an organization for ability users to protect the weak and fight for justice.

Armed Detective Agency vs Port Mafia Arc
After Atsushi's abduction by the Port Mafia and with several Agency members agreeing to leave the young man to his fate, Fukuzawa stepped in at Tanizaki Naomi's initiative. Despite his organization entrusted at that time with the task to protect some government officials, Fukuzawa ordered all Agency members to drop the mission until Atsushi's safe return, as, according to his words, nothing could be more important than saving a companion in danger. He was later seen along his subordinates, thinking about potential leads in Atsushi's disappearance. After hitting a dead end, he asked for Ranpo and his deductive-reasoning skills in exchange for Fukuzawa praising him. With Ranpo having found where Atsushi is, Fukuzawa gave Kunikida the keys of the Agency's boat and asked him to bring Atsushi back at all costs.

With Kyouka and Atsushi out of danger, Fukuzawa summoned Kyouka's presence at the Agency. The young girl requested her right to stay from Fukuzawa who, having a very soft spot for cute things including Kyouka's face, could not refuse.

In the manga, when police officer Minoura suspected Kyouka to be the young girl who is on the police wanted list for being a murderer, Fukuzawa eventually claimed Kyouka to be his granddaughter. Minoura believed him as both wore the same stern looks and were "cut from the same mold".

When members of an American organization called The Guild paid a visit to the Agency, Fukuzawa was offered by the leader of the Guild, Francis Fitzgerald, a great amount of money in exchange for the Ability Business Permit, a document granted by the government allowing the Agency to run ability-based business. Fukuzawa dryly refused, telling that neither the lives nor the permit of the Agency could be bought, as the permit embodied the hope of the government and Natsume's efforts to found the Agency.

Trivia

 * So far it has been shown Kunikida is the closest detective to him than any other. Fukuzawa's trust over him is great enough to leave him in charge of Osamu Dazai's entrance exam and other tasks, take him as his disciple and always share a match of Go after work.
 * After Fukuzawa saved Ranpo from his abduction, he scolded the latter and somehow "tamed" the young detective.
 * Fukuzawa and Mori were affiliated with each other in the past before either of them became the leaders of their respective organizations. Both were under the tutelage of Natsume Soseki and were trained to maintain a balance of power that would protect Yokohama.
