Life is an Unknown Course.Thinking that Haruna is possessed, Erika calls Kasane to warn her about Nasujima. Shingen approaches Kasane with the intention of purchasing her Saika, which transformed from wires into a sword. Aoba surprises Chikage with the appearance of biker gangs and thugs from other prefectures as new members of the Dollars. Masaomi is startled when Mikado says that the biker gangs and thugs were brought them to Ikebukuro by leaving threats about their families. After Mikado reveals his plans to shut down the Dollars since people are getting hurt, he suddenly points a gun at Masaomi. Anri, Walker and the others find Erika, soon realizing that she is wearing red tinted contact lenses to blend in with the crowd. There is news about shooting incidents involving the Dollars at the police station and the home of Dougen Awakusu, the head of the Awakusu Group. Mikado, responsible for the shootings, wants to end the Dollars in a perfect way, so that this gang will become an urban legend. As Masaomi tries to reason with Mikado, a gunshot is heard. Meanwhile, Shizuo continues to chase Izaya, ending up to where Aoba and Chikage are located in the streets in the middle of the crowd. Elsewhere, Kasane finds Shinra, apologizing for kidnapping him. She notices that his will is strong enough to resist her Saika, and he rejects her sentiment of being loved since he has genuine feelings for Celty. Shinra then asks Kasane for a favor. Although Mikado fired the gun, the bullet only grazes Masaomi's face. Masaomi gets on top of Mikado and punches him, but Mikado retaliates by pulling out a glove pistol, which was given to him by Hiroto, onto Masaomi's left leg. Akabayashi surmises that Aozaki was going to use the shooting incidents as an excuse to get rid of Mikado, and then find someone else to take his place. However, Akabayashi and Aozaki both learn that the bullets used at the shooting incidents were not from the gun that Aozaki gave Mikado. Ran and his crew find Kyohei and the others inside the van, but Ran notices that Walker is not there. Walker appears on top of Saburo's van with a fire extinguisher flamethrower to ward off Ran and his crew in order for Kyohei and the others to escape. After spotting Shizuo, Nasujima orders the Saika Army to infiltrate Russia Sushi in order to find Tom. Seeing Masaomi shot, Mikado realizes that he has the potential to make everyone around him suffer. Deciding that he cannot allow himself to keep going, Mikado puts his glove pistol to his head. Despite Masaomi's pleas, another gunshot is heard.
