I apologize, but the text you provided is in Chinese (Simplified), not Japanese. The translation is: "We Viola Knights"

I don't know why I was blown away. Something must have been done to my body—my memories themselves are vague. When I regained consciousness, I found myself piloting a strange machine. Apparently, it's a machine called a Senki, but it's a bit different from other combat machines. And this machine called itself Alice. We were picked up by the Knights. Though they're called the Knights, they're actually a group of prospectors who search for ore veins and mine them. The reason they're called the Knights is apparently because they possess combat machines for defeating giant beasts that inhabit the areas around their mining sites. Come to think of it, they do bear some resemblance to medieval metal armor... This is a story set in such a world. I'm writing it as a fantasy, more or less. After all, advanced science is said to be the same as magic...
