Of course, this is just my opinion, you really don't need to change the story in any way, because it's great. It was just a preference that I would have accepted better, but it's great the way it is.
Divindade_Fantasma:Someone a little simple, who didn't see him for his abilities, and who would see him for who he really is, and more importantly was originally from this world would make the story more interesting to read
Hmm...she is too weak compared to MC who has SSS Rank skill. She will always be a liability on him. Wish if she too had a SSS Rank unique skill just as broken which can't be copied then it would have made more interesting. And their feelings feels Little forced with how she is starting to get conscious of Rey unlike before ever and how she doesn't think of him as creepy unlike other Guy. Would be good if they are only friends in future or break up later or something. Well it's all personal views. Above all else excellent work keep it up.
