As in the Information corner described, the genres are :
Comedy, Ecchi, Shounen and Supernatural, however, I will also mention that there is a little bit of Romance and a whole lot of Harem in this Manga.
Other genres that could be added would be School life or Slice of Life and maybe a bit drama.
As you can read in the Synopsis, the Manga starts incredible, in more than one way. The start is a very funny one and the funny part doesn't seem to end at all. The whole Manga mostly consists of funny perverted events triggered by the main Character.
About the Characters:
There is the main
Character Nanjou Shinobu, a funny guy who is quite popular and about the female Characters in this manga,... I won't mention that much, since I want you guys to read this manga, but as a little "spoiler":
Super cute girls with big "you know what I mean",... yes,... big boo...I mean hearts!
The art is very good. As mentioned above, the girls are very cute. The main Char isn't drawn bad as well.
The Manga had an amazing start, but somehow it slowed down quite a lot after a while. It's not that bad, since there is still a little bit of a story and a lot of fanservice, but maybe...you know...more story...more love...some bad guys?
I enjoyed the manga a lot, which made me give the Enjoyment an outstanding 10. Overall, I've gave this manga a 9, since I absolutely love this type of manga.
I recommend it to everyone and especially to those who loves, Comedy, Ecchi, Harem and School life/ Slice of Life Mangas.
