Fukami is a high school janitor whose father was a gangster. He works at the school as a janitor instead of belonging to the gang so he can watch out for Yui, the daughter of his deceased father's brother Majima Yoshiki. One day, a gang feud erupts and Yoshiki is killed. Yui becomes the next target.

In this new season, Miyuki faces even more changes: a rival real estate firm enters the scene, a new convenience store opens, and new members join the shopping district, pushing her passion for evening drinks to a whole new level.
