This is one of your typical time travel Mangas, where the MC goes back in time for some unknown reason and starts his journey to become an op character. If you love this type of genre, then you will love this manga, since it contains all the typical elements you expect of this kind of story. I would like to state that the latest chapter, as of writing this, is chapter 8.
The story is 9/10 just because it lacks originality. This isn't the first time travel manga and it won't be the last, so if you are expecting something new then you won't
find it here. That being said, just like with any other genre, if you love hard working, overpowered MCs, with otherworldly/extraordinary knowledge then the story is pretty interesting.
The Art is 10/10 since I didn't find any flaws with it. Keep in mind however that unless the art is obviously shifty I might not have detected it, so other people could see it as an 8 or 9.
The character is 7/10. There weren't any extraordinary characters and all of them till now we're pretty generic. We have the gentle beautiful MILF, and the brutish dad whom are very lovey dovey in front of their son. We also have the stubborn enemy who then turns to be a good friend, and the beautiful chick who is interested in the MC. All the characters are pretty generic, but they aren't badly designed or anything, which is why this is the lowest scored category for me.
The enjoyment is 10/10 because I love this type of genre. It has some elements that other time traveller Mangas don't which added to my enjoyment.
Overall, aside from the generic characters, this is one of the best time traveller Mangas I have read. If you are like me, and you like op MCs who turn the world upside down, then you are going to love this.
