In the world of Yubimane, everything's different, but possible. Divided by four main places called Mangers, are Escapade, Ashiwaru, Dokudune, and Pixiecity. But Pixiecity is not like the other Mangers. 60 years ago, Pixiecity had an overflow. Yubimane's first overflow. Only 500 people could inhabit Pixiecity, so, they went away at remodeling the gutters, and transformed it into a city they named Bokudon. The first people to step foot in Bokudon were 6 young kids who dreamed of living in Pixiecity. However, Bokudon was no perfect wonderland, for fights and gang wars broke out. 5 years later, color gangs made their way into Bokudon, and trouble was started. But the leader, Sakita Momo, changed that. She created family gangs she called Junjori's. This made sure no one got hurt. But soon, The War Of '85 happened. The Junjori's fought for blood and revenge. The Sakita Junjori and the Motoyoshi Junjori destroyed themselves with every attack. Now, 30 years later, a new generation of people have entered, but three young kids wish for one thing in Bokudon:
