The Dragon Commander

Issei Hyoudou is your standard, every day high school student that's rather perverse. But what people don't realize is that he has a secret side to his personality: he loves war ships, but there are three that have his heart: the USS Enterprise, KMS Bismarck, and IJN Musashi. When an alien race known as the Sirens come to Earth and practically destroy everything he knows and loves, Issei finds three strange cubes that were hidden by his parents. What secrets do these cubes hide, and what other secrets are out in the world? Issei will soon find himself at the epicenter of not only one war, but multiple that are not just physical, but mental and emotional as well.
