Kokonoi Hajime / Koko ‐Tokyo Revengers

Hajime Kokonoi, or Koko, is a Staff Officer of the Kanto Manji Gang. Prior to his membership in Kanto Manji, he was the 10th Generation Black Dragon Elite Guard Captain and later, a member of the First Division Tokyo Manji Gang. Koko once joined Tenjiku as its Treasurer. In the latest timeline, he is a Seventh Division Member of Toman. But he was a major antagonist in the Black Dragon and Tenjiku Arcs.

Appearance: Koko has a lean build and tall stature. He appears to have brown almond-shaped eyes in the manga but black irises in the anime adaptation. He has thin arch eyebrows, ovular ears, and fair skin. Koko also wears a golden dangling earring on his right earlobe.

In 2008 with wavy black hair fashioned in a death hawk style combed to the right, leaving the left side of his head trimmed and split in equal furrows. He is most often seen wearing the standard Kanto Manji Gang uniform.

In an alternate present timeline of 2018 where he is an executive in Bonten, Koko grows his hair to shoulder-length and dyes it white while still maintaining his unique parted hairstyle from his teenage years. He wears a different set of dangling earrings on his right ear and has the Bonten logo tattooed on the left side of his head.

Personality:

Koko sees the world as a series of calculations. This was a result of a traumatic mishap he encountered at a young age when he failed to save Akane Inui from a house fire that gave her multiple third-degree burns and sent her in critical condition. This event was Koko’s stepping stone to spending his childhood as a leader for an organized band of thieves to illegally amass money for Akane’s costly treatment plan and, simultaneously, the beginning of his inclination toward monetary gain. Although seemingly materialistic at first, Koko’s past proves that this obsession was out of hopelessness.

Due to his financial capabilities, Koko is also sought-after by reputable gangs to use him to their own advantage. For this reason, he was regarded as a pawn and his obsession toward money intensified.

Upon hearing of Akane’s passing, Koko was unable to face reality and cope with the tragedy as he had failed to earn enough funds to keep her alive, selflessly taking the blame to himself.

At a complete loss, he soon attached himself to Akane’s younger brother, Inupi, as a substitute for her absence, as well as a means of preventing himself from collapsing internally. Eventually, Koko learns to detach himself from Inupi and continue a life of delinquency alone, by which his protectiveness toward him, whom he views as a living remnant of Akane's existence, is shown.

Akane Inui: Koko used to hang out with Seishu and Akane, Seishu's older sister of five years, as children. Koko found Akane pretty and compared her features to Seishu's. He tried to kiss her when she was asleep at the library, but she woke up. She told him he should only kiss the person he likes. Later, Koko confessed his feelings to her. Akane told him she would wait until they were adults. When the Inuis' building caught fire, Koko rushed inside to save her. But, due to their resemblance, he saved Seishu instead, leaving Akane behind. At the hospital, Akane suffered severe burns all over her body and was in a coma. Seishu revealed to Koko that his family did not have enough money to pay for Akane's treatment. In order to gain money and save Akane, Koko became the leader of a small gang of thugs. Unfortunately, she died before he could collect enough money to pay for Akane's treatment. Even though he could not reach his goal, Koko still continued to try and gain money as he had become famous in the criminal world for his financial power.

BLACK DRAGONS: Seishu Inui: Seishu and Kokonoi are childhood friends. Koko was in love with Seishu's older sister, Akane. When the Inuis' house caught fire, Koko saved Seishu thinking he was Akane. After Akane's death, Koko stayed by Seishu's side. Together, they recruited Taiju Shiba to reform the Black Dragons. When Taiju Shiba lost to the Tokyo Manji Gang, they both joined Hanagaki's 1st Division, thus merging the two gangs. Later, they were captured by Mucho. To save Seishu and Hanagaki, Koko agreed to join Tenjiku.

Later, when confronted by Inupi about his decision to join Tenjiku, apparently of his own will, Koko tells Inupi to join Tenjiku as well, though the offer is refused. While Koko and Inupi consistently fight on opposing sides, following the Black Dragon Arc, Koko is consistently hesitant to attack or injure Inupi, still maintaining respect and care for him, as the two have been close since childhood. While fighting the Kanto Manji Gang, and Inupi is losing in his battle to Keizo Arashi and Wakasa Imaushi, Koko is finally convinced to fight alongside Inupi once again, still caring for him even after having spent two years apart.

Taiju Shiba: Taiju Shiba first came to Kokonoi for his financial abilities. Koko introduced him to Seishu as a potential leader for the 10th Generation of the Black Dragon. Seishu and Koko became commanders under his leadership. Koko did not hesitate to betray him for money and admitted to prefer power over loyalty. Thus, when Taiju Shiba lost to the Tokyo Manji Gang, Kokonoi left as Taiju had lost his power and utility.

TOKYO MANJI GANG Manjiro Sano: Koko was briefly under Mikey as a member of Toman’s first division, and later when Mikey formed the Kanto Manji Gang. Koko was also a member of the Bonten gang in the future, which was led by Mikey. Koko states that, while a member of the Kanto Manji Gang, he’s happy following Mikey, because it’s like “betting on the winning horse.” Aside from his gang membership under Mikey’s leadership, Koko’s relations to Mikey are otherwise unclear.

Koko aren’t shown interacting very often, Koko states that he won’t do anything to disturb the peace of the first division, displaying a baseline level of respect for Takemichi and his ability to command others. Later, when asked by Inupi about what he plans on doing after the Kanto Incident, Koko comments that while he doesn’t plan on rejoining Toman, he respects Inupi’s choice of sticking with Takemichi, calling Takemichi a “good man.”

Skills and Abilities: Financial Capability: Koko has unparalleled financial capability that contributes to his prodigious money-making reputation. After the Inui family's house fire, Koko researched multiple forms of making money by reading books, where he learned profitable methods that a minor like him could execute. As a result, he was capable of initiating criminal schemes specific to theft for wealthy clients, then would cyclically invest money in growing his syndicate to perform schemes on a larger scale. This methodology would, in turn, create greater profits for himself.

His monetary ability is recognized as a well-sought asset among organizations, therefore making him a major figure in multiple present timelines, wherein he serves as a top executive in the more well-structured and dangerous gang organizations. Usually in charge of the finances, Koko is known as a central piece for an organization's success.

Authority: Koko would often take the position of a Treasurer in a gang and be ranked as a member of the top administration. His authoritative duties are focused on finances, but he once assumed the position as Elite Guard Captain in the 10th Generation Black Dragon.

Fighting Prowess: Koko is shown to be a capable fighter, having the capacity to fight in par against Inupi. He was also shown to be quite a capable opponent to Keizo Arashi during the final battle between the Second Generation Toman and the Kanto Manji Gang.
