Van Gang

The Van Gang is a group made up of Kyouhei Kadota, Walker Yumasaki, Erika Karisawa, and Saburo Togusa, along with some of their close friends.

Background
The main four members, along with Shimada, are all former members of the Blue Squares. Kyouhei and Shimada accepted younger, wilder members like Walker and Erika into their group to keep them in check. Walker once stated that the gang's loyalty is to Kyouhei before any other organization, and they followed him in turning against the Blue Squares' leaders and leaving the gang. They are currently part of the Dollars and are widely known to be a separate group that operates within the gang, where they are considered a formidable force and have a wide circle of contacts.

Dollars/Mika Harima Arc
Walker and Erika are introduced to Mikado Ryuugamine shortly after he moves to Ikebukuro, and afterward they and Shimada torture a thug for information on Kaztano's kidnapping and the human trafficking ring. In the anime, they bring Mika Harima to the first Dollars meeting to meet with Celty.

Saika Arc
The gang plays an important role in the slasher incident when they crash their van into Shuuji Niekawa to save Anri Sonohara. Immediately after, Shizuo Heiwajima rips off the door to their van to use as a shield when attacking Niekawa. Walker later replaces this door with an itasha door, to Saburo's chagrin.

Yellow Scarves Arc
Kyouhei is a strong voice of support online for the continuation of the Dollars, though he is critical of the Dollars' silent leader. They meet with Masaomi Kida to discuss rising tensions between the Dollars and the Yellow Scarves and defend the Dollars from accusations of their involvement with the slasher, vowing to see the conflict through, even if it turns into gang war. During the final confrontation between the two gangs and the slasher, Kyouhei and Saburo and a large group of their close contacts disguise themselves as Yellow Scarves members, infiltrate a meeting, and turn on the color gang, defeating the faction of former Blue Squares and helping end the gang war.

After Kyouhei's fight with Chikage, they save Non, Rio and her friends from their kidnappers.
