His role that you find out in the end was to deal with a thing called Gaia(ADemonShield or entity).But at the start he doesnt know why is there or who sent him. He spends his days helping others out and running from girls while trying to fight the people who want to start a war. If you like Harem, Robot fights, and a good guy who is badass this anime is for you.
