For me, it may be a slight chance of 18+/Hentai stuff (if you read Ari-chan's disclaimer on her fanart in
Deviantart or the quick summary of volume 3 on
MangaFox) you can sort of get the idea of what sensei drew. This manga might also be just 13+ though, which is the normal rating.
What do you think is the rating of this manga? Do you think sensei has gotten a bit different this time or do you think that it's about time that sensei has done something like this?
