Nagoya!! Commander Izumi`s Past

Summer vacation arrives. Hoping to ride as many shinkansen as he can during break, Hayato quickly volunteers to fill in for Ryūji—wounded in the last battle—on a mission to the Nagoya branch. Hayato boards the Tōkaidō Shinkansen for Nagoya. Then Commander Izumi Shinpei sits down in the next seat. As Hayato tenses up, alone with the commander, Izumi starts to share an unexpected past. It's a story of his memories with Hayato's father, Hokuto.
