So we have 3D Kanojo-Real Girl . What seems to be another typical shoujo manga (which it kinda is) does indeed do some things a lot better than others. The story is character based and revolves around a third year high schooler boy otaku who is , well your typical otaku he does all night anime watching , reads lots of manga , plays lot's of games and so on. And his counterpart is a strange and beautiful girl who somehow comes to like him. Since I don't wanna spoil anything that's all the story you get but keep in mind that the ending seems abit rushed and out of place to some extent and might leave you unsatisfied but the first 20 chapters at the very least are really good.
The best thing about the manga is it's art. To be honest I was really impressed by the quality of it the only thing annoying me is that many side characters esp girls were drawn really alike and you could get confused at times other than that it has a really good pencil based art which is easy to get used to and enjoy.
The characters are really well done as well. Not only the MCs but also the side characters were really put together with though which were amazing at times.
Overall I'd recommend this to shoujo lovers and between this and the anime I prefer the manga myself since it feels more relaxed than the rushed adaptation in the anime.
