My Mecha System

Alex has reincarnated as Arthur Wright with a mysterious system on the planet Tera 4. Two years into the military academy an alarm has been raised in the empire. All military assets are to be deployed to stop an empire wide invasion force. Cadets are forced to stay behind while the military goes to take on the threat from the fringes of the galaxy. The world returns to daily life until the planetary defenses come on line in the face of an unknown invasion force. Communication is cut off from the rest of the empire and with the planetary defense force taking on the unknown threat, Arthur and a small team of cadets take to their mechas in a campaign that will decide the fate of the planet and will take him on a perilous journey through a galaxy wide war.
