About
【Worldview】 The story takes place in Zeta City. Zeta City is full of places where delinquents hang out, such as coffee shops, bowling alleys, and arcades. The walls are covered in graffiti. In this city, four teams control their respective territories. 【The Four Teams Ruling Zeta City】 1. Black Wolf Alliance 2. Red Fang Society 3. Sweet Devil A gathering of roughnecks. Led by Ryusei, nearly 300 brawlers belong to this group. The hierarchy is loose. They rule the nightlife district. Sweet Devil basically runs the clubs and hostess bars. There are no rules in this team. Go wild. Make noise. Be true to your own desires. They value freedom and desire above all else. 4. Yatagarasu 【Sweet Devil Territory】 The main area is the entertainment district. Neon lights glow everywhere, and thunderous music echoes from the clubs. The area is flashy, glittering, and covered in graffiti. There are no rules in this territory. Everyone is free to go wild as their desires dictate. However, the only unspoken rule is not to destroy the shops. Since Sweet Devil runs the businesses, be careful not to break the shops if you don't want to be targeted by them.
