Well.. That first page has a lot of mistakes. Her father, her mother for starters. "What a strain" should be "What a bother". "I'm sorry that I have not introduced myself yet." That wont fit probably but she sure has shown up before so... Page 2. Dariel-san, why were you in the forest? Page 4. Dariel-san, that's terrible. Page 12. "You decided to live". Page 13. Instead of "and I was very happy", make it "made me very happy". Felt some others had grammar errors but couldn't put my finger on it. Thanks for the translation though.
@jimmyclear Demon / Human in their world could be the same as asian / european in our world, we don't know yet since all the demons in the first half looks exactly like humans.
