Um, I just watched the hentai anime, Creamy Pie, and when I searched for it on here, I couldn't find it.

I was going to add it here,but is hentai allowed?
And if it is do we have to post a appropriate picture?
Because I can't find a picture of the series or characters that doesn't have something erotic in it or boobs showing.
Also on Myanimelist it says that the studio name is unknown.
So are hentai like that added or is there a different database specifically made for hentai?

Yes, we do allow hentai OVAs in the database. However, any images MUST be Safe for Work. If you want to add the series/characters, you'll need to submit the request in the Title Request Thread. Make sure you provide all the information in the form there. Then you would have to go through the anime and take screenshots of the characters that are Safe for Work in order to make a character submission.

Also, I did some looking, and the studio for Creamy Pie is Queen Bee.
