Mitsuya and other members of his gang meet Taiju with a special offer following which he promises to let Hakkai join Black Dragon in the fourth episode of 'Tokyo Revengers' season 2 episode 4 or 'Tokyo Revengers: Christmas Showdown.' SPOILERS AHEAD
Recap of Season 2 Episode 4 of Tokyo Revengers
Mitsuya asks Hakkai to come meet his brother in the Black Dragon leader on the condition that he release Yuzuha.
After a brief discussion, Taiju agrees to all the conditions. Chifuyu and Takemichi discuss the present situation. The latter believes that Hakkai was going to kill his brother to protect his sister.
Hakkai, the duo's spokesman, interrupts their discussion to discuss his life. Hakkai reveals how his brother has always manipulated people for his own purposes. Hakkai claims that his brother isn't trustworthy and that the friendship he formed with Mitsuya is untrue.
Takemichi and Chifuyu are shocked by this revelation, who are naturally alarmed by the fact that they have little time to spare. Takemichi realizes that there is only one way to alter the future right now, and that is to crush Black Dragon before Hakkai does something stupid. Chifuyu and Takemichi meet other Toman members at a restaurant and explain the present situation. However, Mitsuya's truce is used to deceive the duo.
Takemichi and his allies plan to stop Hakkai from killing Taiju, according to Tokyo Revengers Season 2 Episode 4 finale.
Takemichi and Chifuyu are left to contemplate other possibilities in the restaurant after Toman's other members reject their proposal to crush Black Dragon. He then threatens to cut him with a broken piece of glass. Hanma put a knife to Takemichi's neck, threatening to attack him if he violates Toman's rules and encourages infighting.
Kisaki announces that he has an informant in Black Dragon who is naturally concerned about his safety. After he is offered 10,000 yen and his safety is assured, he is about to disclose some critical information but Koko enters the room at that exact moment with two other members of the biker gang.
Koko refuses to reveal whatever secret they want to learn for 100,000 yen when he meets Takemichi and his friends. He learns that Taiju is usually never alone except for Christmas. He then tells Takemichi that he did not put much effort to study when Taiju will be alone to kill him.
Takemichi and Kisaki believe that they must not allow Hakkai to follow his plans no matter what. Although Takemichi is naturally interested to learn such valuable information, he is also concerned about Kisaki. He has failed to discover the true nature of Kisaki's intention, which appears to be real frightening to him.
