I think it's Diamond weapon.
I look stronger than you look <--- they're big ugly monsters
though my master are not <--- The planet is what controls them and it's at it's weakest time during the meteor being summoned.
I hit harder than anyone else <--- they have big strong attacks they are the planets source of protection so of course they're going to be able to hit as hard as possible. But my theory on this is they hit harder than any HUMAN being.
though it's weak <---- It is possible to defeat. And very easy to beat
I can be gained easily than you think <--- It comes straight to you in the story line for you to beat.
though I seem to live in ruins <----- it could be the reference to the northern crater which is ruins from the previous meteor.
