Despite being an isekai he seems of a completely different category the story is very beautiful certainly among the most original I've seen, the protagonist is not very powerful but he grows with good power ups the way in which the protagonist relates to the other characters is good his goal is particular and different from the other protagonists perfectly in line with the story, the side cast is not the best developed only in the deuteragonist and his "parents" for the rest nothing special even worse as regards the female cast even worse while the battles are simple and contain cgi but they are well done, taking everything into account I can say that it is a very valid work.
