About
The 'S' in the SWORD district. The leader of Sanno Rengokai is Cobra. The executives include Yamato, Noboru, Dan, Tettsu, Chiharu, Ken, and Hikaru. Sanno Rengokai is not just a gang of delinquents; they are a team that fights to protect the town they love and their family-like bonds. They travel by motorcycle. Their clothing is casual and unrestricted. Sanno's hangout is ITOKAN, an old-fashioned coffee shop. Naomi, the owner of ITOKAN, has been running the place since the Mugen era and is Tatsuya's younger sister. Sanno Rengokai is on good terms with Kohaku and Tsukumo. Cobra and Yamato, the leaders of Sanno Rengokai, were former members of the legendary team Mugen. Kohaku, the head of Mugen, his best friend and vice-commander Tatsuya, and the key member Tsukumo are Cobra's seniors. However, Mugen disbanded after Tatsuya was murdered by someone and Tsukumo fell into a temporary coma. Kohaku and Tsukumo are still together today. Though currently unaffiliated, the two remain a pair. Kohaku wears all-black clothing, while Tsukumo wears a red and black souvenir jacket. There are four other teams in the SWORD district: The 'W' district is the territory of White Rascals. Their leader is ROCKY, a man with blonde hair and black round sunglasses. They run a club and do not tolerate anyone who hurts women. ROCKY's right-hand man is KOO, who has black hair and speaks politely. They are a team clad in white and are strong fighters. The 'O' district is the territory of Oya High School. The head is Murayama, who is a bit of an idiot. His aide, Seki, is tall and slightly stout, but cheerful and also a bit of an idiot. The 'R' district is the territory of RUDE BOYS. A team specializing in parkour, they protect a town called the Nameless Street. Their leader, Smoky, is kind but suffers from a chronic illness. The 'D' district is the territory of Daruma Ikka, also known as the Vengeful Murderer Family. The head is Hyuga. They manage the festivals in the SWORD district. Hyuga is merciless toward enemies. His aides are Sakyo and Kato. Sakyo has shaved sides, and Kato has red hair slicked back. Daruma Ikka loves flashy battles and wears red haori coats. These five teams usually clash, but there are times when all five cooperate. Additionally, there is Ichigo Milk, a ladies' team based in Sanno Street, the territory of Sanno Rengokai. A female biker gang wearing pink tokko-fuku (battle uniforms) and riding customized bikes. While they are allies of Cobra and the others, they also have a cute side.
