This looks kinda happy and cheerful but... it got dark pretty fast. I'm glad I opened my mdex home to find this manga. >< Now on to the second chapter-
@Flashplayer0CD - Okinawans weren't on any side. They were brainwashed into thinking they were Japanese after Japanese assimilation process during the Meiji era while the Japanese did not accept them as "Japanese" and Okinawans became shields for Japan. They were the innocent who got pushed into the middle, as they still are.
