Yellow Scarves

The Yellow Scarves is a color gang that was started by a group of middle schoolers in Ikebukuro. The gang was famous for its rivalry against the Blue Squares, another color gang. Members of the Yellow Scarves can be recognized by their yellow bandannas or other yellow attire.

Background
The Yellow Scarves was founded by the middle schooler Masaomi Kida and his group of friends. The group began as a way to find adventure and have fun. They would go around the city in a large group and spend their whole day fighting. The leader soon started a relationship with a girl he met in the city named Saki, and through her met the information broker Izaya Orihara. The Yellow Scarves were in a constant battle with another color gang, the older Blue Squares. Whenever Masaomi was unaware of what he should do, he would ask Saki, who would then suggest he talk to Izaya. Frustrated with the constant casualties the gang was taking, Masaomi decided to rely on the information Izaya would give him. This resulted in a turn in power between the two groups. The Blue Squares decided to take drastic measures, kidnapping Saki and using her to threaten Masaomi. After hearing what the Blue Squares had done, Kyohei Kadota and his inner circle defected from the gang and rescued Saki. Soon after, the leader of the Blue Squares, Ran Izumii, was arrested and the color gang disbanded. With Saki in the hospital unable to walk, Masaomi resigned as a member of the Yellow Scarves. Even with the defection of their leader, the Yellow Scarves continued to roam the streets of Ikebukuro over the next two years, maintaining their notorious reputation for causing trouble.

Yellow Scarves Arc
The Yellow Scarves find themselves helpless when rumors about "The Black Rider" and The Slasher incidents began. In fear of losing control of the city, they attempt to re-recruit their former leader Masaomi Kida, but he refuses to return. He soon changes his mind when a Slasher incident results in his close friend Anri Sonohara being hospitalized. They come to the conclusion that the Slasher, the Black Rider, and the Dollars are working together. Their objective is to find as much information as they can on the Slasher and the leader of the Dollars, but not to cause any harm or trouble. Many members, acting out of fear and frustration, begin beating up anyone they believe to be a Dollars member. The Dollars take their first casualty when a group of older Yellow Scarves members led by Horada send Ryo Takiguchi to the hospital.

When Masaomi confront Horada during a Yellow Scarves meeting about the growing number of violent incidents targeting the Dollars, Horada reveals that he and his followers are former members of the Blue Squares who defected to the Yellow Scarves, and he plans to get rid of Masaomi and control the gang. The Yellow Scarves have been infiltrated by Kyouhei, Saburo, and many of their friends in the Dollars, however, who attack Horada's group. In the chaos, the leaders of the Dollars and Saika Army are able to sort out misunderstandings with Masaomi. Shortly after, Masaomi leaves the city with Saki, and the Yellow Scarves fade into the city background again.
