History
Doubt has been a group of scouts even before the formation of White Rascals. Although they are not as strong as Mighty Warriors in term of strength, they have a large number of members. They used to have Kizzy and Kaito as a part of the group. They have a forceful way of scouting girls, even going as far as kidnapping them. After Kizzy and Kaito met Rocky, the two left the group to help Rocky form the White Rascals. Due to the the White Rascals' benevolent and caring attitude toward girls, this formed a hostile relationship between the two gangs. After some time, Doubt and White Rascals had a huge brawl at the train station in SWORD. During the brawl, Ranmaru not only attacked the opposing group but even innocent civilians alike. Ranmaru was then detained and the train station was shut down.

They were hired by Chanson along with Mighty Warriors to destroy SWORD, as part of their plan of taking over the region. Doubt caused a huge commotion, such as kidnapping girls in the different areas of SWORD, damaging the shopping district in Sannoh, and planting explosives in Nameless city which caused a lot of casualties.

After the fight in the container yard, Ranmaru was released from prison. A huge fight between Doubt and White Rascals is bound to happen again. This made Rocky reject the SWORD alliance proposal by Cobra, stating that the business of the White Rascals should be handled by their own. Doubt was then assisted by the Prison Gang as part of Jesse's job to cause a disturbance in SWORD. Ranmaru initiated a brawl among the members of Doubt and Prison Gang, to find out who is worthy of joining him. The rules of his initiation is an all-out brawl, each person has a coin and you pass the test if you collect 5 coins.

Doubt and White Rascals would then have a brawl in the station where they had their previous fight. White Rascals was overwhelmed with numbers this time, but Sannoh, Oya High, Rude Boys, and Daruma would eventually arrive to help them. After the arrival of the four gangs, the tide of the battle has been shifted to the favor of SWORD. However, Ice and the rest of the Mighty Warriors would also join the fight to help Jesse, this retained the balance of the battle. The fight was interrupted at the arrival of Zenshin-kai, who was enraged of the fact that the brawl would affect the casino project.
