Dollars

The Dollars is an online group. Anyone is allowed to join, but only through invitations received via email. Although the organization mainly exists online, several groups have taken the name 'Dollars' and used it for their own ends. As such, the Dollars are regarded as a "color gang without a color" and have gained a fierce reputation around Ikebukuro.

Background
The Dollars were originally created by Mikado Ryuugamine and a few internet friends as a joke. When new of an unexplained event would air in Ikebukuro, he and his friends, under multiple accounts, would claim it as the work of the Dollars. They created a website for the group to add weight to their story and sent out a small number of invitations. One unidentifiable member, later revealed to be Izaya Orihara, continued sending out invitations long after the original group stopped. As the group began to expand exponentially, all of the original founders became frightened and deserted the project, except for Mikado. As the gang's reputation became more widely known, some people began using the name to commit crimes and do wrong. In response, Mikado suggested on the Dollars forum that members started doing good deeds around the city. While he was mocked at first, the idea resonated with a few members and more and more Dollars began to fix whatever the other members did, increasing the amount of talk about the group spreading across the internet.

Many members, including Kyouhei Kadota and Ryo Takiguchi, were drawn to the Dollars by their unwillingness to lead a quiet life and the group's promise of no rules, no restrictions, and no chain of command. Many members are curious about the leader of the organization but most are content with the mystery because the leader never hands down orders.

Dollars/Mika Harima Arc
The Dollars made their first public appearance in Ikebukuro when the leader, Mikado Ryuugamine, sent out an invitation to a meetup to all members via email. As numerous members gathered at the designated time, Mikado ordered them to only surround and stare at Namie Yagiri and her employees. Celty Sturluson made an appearance minutes later, driving her motorcycle down the side of a building. After this incident, rumors about the Dollars increased and the gang became even more famous.

Yellow Scarves Arc
The Dollars became the target of the Yellow Scarves after being thought to be connected with the recent slasher attacks. The Yellow Scarves' returning leader, Masaomi Kida, blamed the Dollars and the slasher for the attack on his close friend Anri Sonohara, ordering Yellow Scarves members to find as much information as they could. As a result, the Yellow Scarves began attacking almost anyone on the streets (since the Dollars have no color), brutally beating them and leaving their tag. The Dollars take their first casualty when Ryo Takiguchi, whom Mikado knows personally, is hospitalized after being assaulted by older members of the Yellow Scarves. Members of the Dollars begin to withdraw and become impatient, wondering why the leader has decided to sit back, some deciding to take their own actions and others opting to leave the group. The Dollars later heard news about a young Raira student being pursued by Yellow Scarves members. The Dollars decided that they would not sit back and let this happen. Matching the description of the girl to his friend Anri, Mikado called out to members to help her escape. Members within the area began aiding Anri in any way they could. Shiri helped by leading her out the back of the Orb Ikebukuro Building. Kaztano made sure she got out the exit, closing the gate behind her. Ryo Takiguchi slowed down Horada, knocking a couple of boxes on him in a store. Rabi-san gave his rabbit costume to Anri in order for her to escape unseen. Simon Brezhnev intimidated her pursuers. When she had safely gotten away, the Dollars members felt renewed hope in the group.

Anri was caught by Horada and his followers later that same night. This time, Shizuo Heiwajima unintentionally came to her rescue, attacking Horada on sight. The Yellow Scarves retaliated by attacking Rabi-san later. This resulted in Mikado Ryuugamine disbanding the gang and closing the BBS on the main site. The members were apparently against this idea and called him irresponsible. The Yellow Scarves committed another attack on the Dollars late that night, this time shooting Shizuo and leaving him to bleed out in the street in the rain, pinning the attack on the orders of Masaomi Kida.

Several Dollars members led by Kyouhei, infiltrate the Yellow Scarves meeting and save Masaomi from Horada and his goons.

When he and his friends have reconciled, Mikado reopens the Dollars webpage.

Akane Arc
Due to the actions of Aoba and the Blue Squares, Chikage and the Toramaru have come to exact revenge on the Dollars. They preform attacks on Dollars members to find those who attacked them. Meanwhile, Aoba and his friends try to recruit Mikado as their leader.

Dollars and Blue Squares Arc
After getting a text from Izaya, a group of rogue Dollars led by Asanuma, attempt to kidnap Non and her friends. Meanwhile, Kyouhei and Chikage end up in a fist fight and Kyouhei barely wins. Asanuma and the rogue Dollars members encounter Kyouhei and Chikage by chance. It ends up becoming a huge brawl, that ends when Shizuo shows up. Shizuo quits the Dollars due to the kidnapping. Mikado, after an encounter with Chikage decides to take Aoba's offer to become the leader of the Blue Squares. He stabs Aoba's hand and uses a bloody piece of paper as a contract.

Members
The Dollars allows anyone to join if they accept an invitation via email. The person is then given the password to access the group's website. Due to the gang's nature, being colorless and a care-free group, it is difficult to identify members on the street and there are few ties between members in real life, though some do meet up casually. Ryo Takiguchi meets up with members he meets online and claims to be able to identify fellow members on the street by their attitude and appearance. Kyouhei Kadota is one of the more well-known and respected members and has a circle of roughly 30 friends within the group whom he calls on when needed.

Trivia

 * Although the gang appears to be named after American currency, the name is actually derived from the Japanese term "dara dara," roughly translating to "useless" and "not doing anything." This is because the gang was created with no purpose in mind, rarely involves itself in any group activities, and its members are "colorless" and "invisible," only identifying themselves as Dollars when specifically asked.
 * Some fans have also created their own online Dollars organization, which exactly resembles the original down to its styling, the largest one spreading out internationally. Similarly to the anime, anyone is welcome and their aim is for the betterment of the world.
 * The password is 'baccano,' the title of a previous work in the Naritaverse.
 * Dollars board username information is from Durarara no Subete.
