Gunparade March

It began in 1945, at the end of the Pacific War. Alien invaders filled the earth’s Skies, and mankind was forced to confront an unprecedented threat. For the first time in human history, people of all cultures came together under one banner. This war has now been raging for over fifty years. Countless lives have been lost, and the Japanese military is now forced to rely on young people such as Atsushi Hayami and his high school class, also known as Unit 5121. This new generation fearlessly struggles on with the aid of the HWT humanoid combat machines and the devastating PBE bomb.

In the year 1945, the most terrible creatures in existence visited the earth: bug-like entities soon to be known as Phantom Beasts. In that time of peril, mankind joined together to expel the threat, only to find that conventional weapons were useless and further damaged the earth. It is now 1999, and the student-wide draft has changed the lives of thousands of teenagers across Japan. While unwillingly fighting in an endless war that started before their births, one group of friends will experience the tragedy of death and the bittersweet joy of love as they struggle to survive.
