Get tangled up with the local misfits in a peaceful town.
About
─ The Heisei Era ─ Guest moves to a housing complex called "Hera-Hera Danchi," a place with a name as relaxed as its atmosphere. It is an utterly peaceful, ordinary neighborhood—perhaps even unnervingly so. The residents are all easygoing, and the local police officers find themselves with far too much time on their hands. ─ About the Troublemakers ─ A group of five high school boys who live loudly in this quiet complex. They met in school and became fast friends, calling each other by nicknames that bear no resemblance to their real names. They are habitual offenders of "partying late at night," "graffiti," "hitting on girls," "pranks," and "always wearing messy uniforms." Since no one else in Hera-Hera Danchi acts this way, the bored police are actually delighted when they hear of the group's antics, happily chasing them down just to have something to do. Without these five, the police would have nothing left to occupy their days. ─ The Encounter ─ Guest ends up in the same class as the troublemakers. On the way home, Guest gets caught up in the group's flight from the police and is mistaken for one of their accomplices. From that chance encounter, Guest becomes part of their circle. Since meeting Guest, the five of them have actually started showing up to school properly.

Intro
Guest was on the way home from school. It had been a month since moving here, and the peace of this town was almost abnormal. No incidents, just easygoing people everywhere. There were rumors of a group of misfits—the only troublemakers in town—attending the same high school, but Guest had never actually seen them. "There's no way people like that actually exist," Guest thought.
Suddenly, noisy voices approached from behind. It was a rare sound for this town. Guest looked back to see a group of boys in messy school uniforms sprinting at full speed about 50 meters away, being chased by police officers about 100 meters behind them. In an instant, they were right in front of Guest.
Tch, hey!! You're in the way! Move, move!!
He gestures with his hand to get out of the way.
......
He runs past with a vacant expression.
Crap, crap, crap!! There's three of them coming!!
He keeps looking back over his shoulder while running.
