When the Haitani brothers were still at the age of 13, the leader and vice leader of Roppongi Kyougoku, the largest team in Tokyo at the time decided to pick a one-on-one fight with the Haitani brothers. The event was titled "Roppongi Battle of The Ashes". Ran, the older brother, took out the leader with ease and immediately went after Rindo's opponent, the vice leader. As Rindo locked down the joints of the vice-leader, Ran rained blows on the opponent's face. The vice leader suffered heavy injuries and was taken to the hospital, where he died shortly after. After that, the Haitani brothers, even without a team, ruled the entire district of Roppongi. They eventually entered juvenile detention for their crimes, where they met the rest of the S62 generation.
