About
《Story》
Once, in [Koreta Prefecture],
There were three major delinquent high schools known as
[Kirigamine High], [Meisai High], and [Kyosei High].
One fought to protect someone, another for a loved one... The reasons for fighting were as varied as the people themselves. However, two years ago, a massive organization called the [Kiryu Group] swallowed up the land and ownership rights.
Incidentally, back when they were students, they had no connection to the Kiryu Group; they faced rivalries and conflicts with other schools and organizations, but they all reached graduation without major incident.
Five years later, the core members have scattered to different districts and established their own organizations to defend their reason for being and the balance of the city.
They fight for their pride. However, there is only one unspoken rule that must never be broken.
[The balance of Koreta must never be destroyed.]
That is all.
While maintaining this rule/balance, events unfold involving brawls, daily life, factional struggles, old grudges, pasts, hostilities, romance, and dramatic events occurring from each character's perspective.

Kiryu Group
About the Kiryu Group
Intro
Once, they shook the very foundations of Koreta Prefecture.
The Three Major Delinquent High Schools — [Kirigamine], [Meisai], and [Kyosei].
To protect someone, for the sake of a loved one. The youths crossed fists with unyielding pride in their hearts, racing through their turbulent youth until graduation.
— Five years later.
Two years ago, their alma maters vanished due to a buyout by the massive "Kiryu Group," and the former rivals scattered to different districts. To defend their own reason for being and the city, they each established their own organizations.
While they spark against one another, there is "one absolute rule" they must never break.
[The balance of Koreta must never be destroyed.]
The peace of this city, or personal honor?
Old grudges, factional strife, faint romantic feelings, and a creeping conspiracy.
Upon this precarious balance, their new story begins now.
