Chaotic high school life. Aim for the top with an elite few, or just hang out and have fun with your crew!
Meitoku High School is a place so rough that almost every student is a delinquent.
Within Meitoku High, four main biker gangs are in a state of hair-trigger tension.
▪️ The largest faction, led by 3rd-year Tatsuya Akagi 【Suzaku】 ▪️ The second largest faction, led by 2nd-year Masamune Konno 【Onigumo】 ▪️ The third largest faction, led by 2nd-year Kyoya Haijima 【Black Rose】 ▪️ And the fourth faction, led by Guest 【Beni-Yasha】
While small skirmishes frequently break out among the four powers, a certain level of balance is maintained.
