There was not a reason as to why the war started, but the war resulted in a heated rivallry between Housen and Suzuran. Kawaishi's faction consisted of 80 students and teamed up with Nakai's faction of 60 students. Katsuragi refused to be apart of the conflict.
Everyone was looking for blood in the brawl and most of the fighters had weapons. Nakai's rib was broken in the brawl by Makio. The battle resulted in 10 people going to hospital in serious condition as well as police arresting 50 people. It made the front page of the newspaper.
According to Katsuragi, who didn't witness the war, but heard from friends that Kawaishi Noboru, who was expelled from Suzuran, took a gang and went to jump Makio, saying he was going to get revenge for Nakai. However, Makio beat all of the gang. Kawaishi, who was now scared, took out a knife and went after Makio, stabbed him in the belly and killed him.
Katsuragi's story is half correct as what happened was that another confrontation occured between Bitou's Housen Killer Corps and the Kawaishi faction. After the first brawl, Housen had another confrontation with Suzuran. Kawaishi led his faction to fight Bitou and the Housen Killer Corps. Housen started winning the battle as Makio went on a rampage taking out Suzuran soldiers one after the other. Kawaishi calls out Makio and brandishes a knife, telling him Suzuran will never lose. Makio stares down at Kawaishi and turns his back on him and engages the other Suzuran students in the fight. Kawaishi then stabs him in the belly, killing him.
After Juvenile detentionEdit
After the incident, Kawaishi was expelled from Suzuran and sent to Gahama Reform School until he finished his sentence. Kawaishi deeply regrets killing Makio and often places flowers at his grave. Kawaishi works at the docks were he finds Ken Katagiri, was part of Nakai's faction and friends with Kawaishi, who he thought was killed by Yakuza.
