I could spend HOURS talking about this manga, and I really do mean hours. This is by far one of my favorites and I'm actually gonna keep this short simply to get my point across:
If you're wondering whether or not to read Kamisama Hajimemashita, read it.
I guess it might not be for everyone but this is not your typical shoujo manga. The main character, Nanami, is a strong, independant female role and although she seems weak and incapable at first, she continues to push on throughout the entirety of the manga. Although this world she is introduced to is new and confusing, she makes an effort to understand everyone and help even if she is not always totally prepared to do so. Over the course of the story, you can see real development in her character and her abilities as her knowledge of this new realm expands.
Tomoe, Nanami's familiar is another story entirely but in the end I also came to love him too. You can genuinely see Nanami's effect on him as he grows and changes by her side.
The other characters are equally as lovable and they all have their own stories to tell. You will fall in love with them and cry with them.
Finally the story in general is just fantastic. You will enter the world of Gods and Yokai and still be reminded of the struggles of the human world and the overall inevitable.
Finishing the last chapter today, I feel like I can truly walk away having learned something.
A warning to those of you who are like me and become committed to the manga but also, unfortunately, can only speak/read english, translations for this manga are slow as of now but there are other ways to find the later installments if you are persistent ;)
I sincerely hope you all read it and wish you the best of luck!
