Aoashi: Midnight Diner

The main character here is Taira Nakamura, a senior member on the same J Youth team as Ashito Aoi, the protagonist of Ao Ashi. Taira is popular with his teammates, but he retired in the middle of his second year of high school, saying he wanted to become a police officer like his father. In this long-awaited side story, we focus on a side of him that was not depicted in the main storyline.
