Takeomi Akashi/Synopsis

History
Takeomi lived life as an ordinary child. He was often overshadowed by others and was rarely in the limelight until his friendship with Shinichiro Sano turned his life around, prompting him to rise the top of the delinquent world during the Black Dragon gang's invincible era. Takeomi was pronounced by Shinichiro as the pioneering generation's Vice President which brought him all the recognition and scrutiny he could not have as a child. His familiarity with his newfound glory eventually led to his downfall when Shinichiro disbanded the First Generation and profoundly unsettled him with shock and greed. Takeomi had complained about his decision to disassemble the gang, but Shinichiro's plans pulled through and he fell even deeper down a dangerous path in life. Eventually, he was succored by his younger sister Senju Kawaragi who had articulated her interest in having him lead a new gang with her, marking his change of his old selfish behavior and the new devotion and loyalty he now holds for his sister and Brahman.

Bonten Arc
As Haruchiyo Sanzu punishes Bonten's traitors by finishing them off, Takeomi is introduced as Bonten's advisor.

Three Deities Arc
Once the Shinjuku delinquent gang Brahman collides with Minato gang Rokuhara Tandai, Takeomi provokes Rokuhara Tandai Representative South Terano by recruiting Takemichi Hanagaki into their gang. However, Kakucho Hitto defies his wishes and voices Rokuhara Tandai's objectives to scout him as well. To Takeomi's chagrin, he ridicules Kakucho's allegiance to South and mentions the death of his former Tenjiku boss Izana Kurokawa, but Kakucho offends him back by mentioning his close confidant and former Black Dragon leader, the late Shinichiro Sano.

As Rokuhara Tandai's upper echelon members appear one by one, Takeomi foments Brahman President Senju Kawaragi to come forward and make her surprise entrance. Eventually, Takeomi calls for the rest of the Brahman executives who threaten Rokuhara Tandai's leaders one on one, but dissolves the boiling encounter when the cops arrive. He first apologizes to Ken Ryuguji for not acting on the confrontation, then flees the scene. At D&D Motors, Takeomi is cornered by Draken who demands him to exclude Takemichi and all former Tokyo Manji Gang members in the dilemma with Rokuhara Tandai. Senju and a confused Takemichi barge in the scene, and the former explains that Brahman's goals align with Draken's to take down the Kanto Manji Gang and save Manjiro Sano from his gang's malicious intentions. Takeomi tells him that he admired Toman's ambitions; he believed in its goals until its disbandment which caused Mikey's downfall. With the Kanto Manji Gang on the run for their wrongdoings, Takeomi states that Brahman's resolve and purpose heighten in defeating them. As Takemichi joins the gang, Takeomi persuades Draken to approve his membership by convincing him of the necessary alliance to stop Mikey.

While out on a shopping spree with Takemichi, Senju tells him that Takeomi is her older brother along with Sanzu, making the three of them collectively be known as the "Mysterious Three Siblings." Senju then tells him that despite Takeomi's support toward her leadership in Brahman, Sanzu remains apathetic toward them. A month later, Takeomi attends a business meeting with Senju regarding Brahman's involvement in a prostitution ring. As Senju disagrees with the company's unclean business, Takeomi reminds her to properly behave in front of a customer and advices her to be more rational with her decisions for Brahman's sake, then praises Mikey's ability to exclude his personal feelings from affecting his decisions at work. Afterward, he attends the general gang meeting where Senju announces a declaration of war against Rokuhara Tandai and the Kanto Manji Gang on the 14th of July, watching in the shadows.

As the battle commences in light of Draken's death, Takeomi rages toward South and forces Brahman to join the fight all the while ignoring Senju's disagreement to continue. As he is almost punched by South, Keizo Arashi and Wakasa Imaushi come to protect him. They fight him in Takeomi's behalf until they are beaten by South, to which Senju takes over with the goal of winning for the sake of her gang. Takeomi is displeased by her actions and begs her to retract from the battle for her safety, but she stubbornly shuns him and plunges South to the ground after recalling Takeomi's selfishness of utilizing Brahman's gold and glory to gain power of his own. Senju awakens the potential she has kept hidden from Takeomi's greed in defeating South, then declares herself as Brahman's true boss soon after. Upon her declaration, Takeomi reminisces his upbringing with the members of the First Generation Black Dragon. He believed himself to be an average child who was profoundly inferior to his close friend Shinichiro, but his promotion as the First Generation Vice President fueled his ego and he became glorified as a notable leader of one of the mightiest gangs in Japan. Eventually, this prideful and privileged disposition led to his downfall as Shinichiro disbanded the First Generation and Takeomi was left to wallow in shame with his tremendous debts. However, he was soon recruited by his sister Senju to be her advisor in a gang she wished to create that deeply followed the principles of the original Black Dragon. Her genuine acceptance of and eagerness to scout him despite his unruly state caused him to devote himself to serving her and Brahman, but as he recalls his history with the gang, he erupts into tears after realizing that he had failed Senju and Brahman both as an older brother and leader. Senju reassures him of his faults and carries the burden of Draken's death and Brahman's failures, then faces South once more as he recovers from her attack.
