Scarlett: Nichijou no Kyoukaisen

Ohno Akito is a military enthusiast who dropped out of school and set up camp on a small island off Okinawa, hoping proximity to American forces would get him close to real hardware. A foreign girl named Shizuka tells him he is in a restricted area. That night he spots a B-2 stealth bomber flying where it has no business being. The next day, trying to get a better look at Kadena Air Base, he runs into Shizuka again — and into something he was not supposed to see.
