nice translation, the are some minor mistakes that can be remedied with a little revision but with how quickly it is being translated is more than good enough.
I'll point out some of the stuff I spotted:
-page 5: "continuing recive" should be continue reciving, "even when fighting the demon king, his power isn't this big...!!" could become even the demon king wasn't this strong
-page 6: "I'm run out" should be I'm running out, "I'm still have" should be I still have
-page 12: "so, is this" should be so, this is
-page 19: "if you broke" should be if you brake
this may not be that accurate since english is not my first language
