When I started reading, I was just hoping for something simple, but not too stupid. The first chapters seemed exactly like that, but very quickly the story began to gain momentum. The story is very thoughtful, there is a justification for many things in the story and the most important thing is to "believe" in it. The prescribed characters (not the One Piece level, of course, but worthily), prescribed rules of the world, interesting references to mythology or other works, and even obscenities are written at an excellent level. My respect to the author, as a person who has read a lot, it is difficult to surprise me, but this story is definitely wonderful (400 chapters have been read at the time of writing the review)
