Makai Tenshi Djibril

Jiburiru: The Devil Angel is a fun laid back hentai with some tame tentacle scenes, with a lot of focus on comedy. It's something you just shouldn't expect to take that seriously. The same can be said for Sex Demon Queen (Yarima Queen) there's some monster and tentacle scenes in that one, but they're extremely tame compared to real h-anime of those genres and above all, this one is a parody of tons of genres. Both are entertaining h-anime's that are easy to enjoy if you want comedy over the sex. 

In many ways, these anime are like night and day, but they also have much in common. Your main hero is a female with superpowers (Miko = demons, Rika = angels), and she fights lots of tentacle monsters. Neither are exactly modern masterpieces of anime, but if you're looking for an ecchi anime to add to your collection, and you liked either of these, you will very likely enjoy the other.
