Chiisana Koi no Uta (2019)

Inspired by a hit song by Mongol800, there is a small town in Okinawa where the US occupation forces are stationed and have fenced off their base. A popular high school band is scouted by a Tokyo-based record company. The band is involved in a car accident, however, shattering many hopes. The band receives a demo tape from a girl who lives on the navy base. They are reinvigorated.
