YO!! N700A And Ryuji's Blues

Synopsis

As Hayato is explaining the difference between the shinkansen "Nozomi" and "Kodama" to Seiryū, a phone call comes in from Ryūji's mother, Kaede. Apparently, Ryūji and his younger brother Tatsumi have had a fight and won't even speak to each other. Wanting to find out what triggered it, Hayato heads to the Nagoya branch with Azusa and Seiryū. Along the way, on the Tōkaidō Shinkansen platform at Tokyo Station, Hayato runs into Higashi Subaru, the supreme commander.
