If you don't know what an anthology is, to make it simple for you, it's something that consist of several short stories which in a manga's case, each chapter being a different story. Manga readers would like to call
those short stories "one-shots", so basically a manga full of one-shots.
Story - 7/10 - Since this manga consist of several short stories, it may be a bit more difficult to rate the story category as a whole.
Just a quick description of each story in case your curious on what to find.
Ch1. Orgy with 1 male and several female characters including a loli.
Ch2-4. Two girls, one being an elf, after one guy. Each get their own chapter and a threesome for the last.
Ch5. Two succubus threesome.
Ch6. Sweet chapter with angel girl.
Ch7. Genderswapped gangbanged.
Ch8. Computer program comes to life as a girl.
Ch9. Futanari incest with humorous ending.
Ch10-11. Tsundere succubus girl with several cute expressions.
Koukuma-Kanojo starts off with artwork of what to come, images of female characters who will appear in each story including several monster girls from elves to angels to succubus. When the story doesn't involve a monster girl, it usually will fall under a different fetish like say genderswapped gangbang or futanari incest rape. What's enjoyable about these stories is they all turn out with a happy or humorous ending, regardless of how it went through. (Aside from the random wolfmen pages in the beginning which doesn't even count as a chapter). Because of this, every story is quite enjoyable and many are very fun & sweet. However, you could label most of the stories as generic and common as a whole in hentai standards.
Art - 10/10 - Hisasi's artwork is fantastic and to have a 180+ pages h-manga with it, even better.
Character - 6/10 - There is quite a variation of female characters provided but they're not too different from what you'd find in hentai in general. Several horny school girls and monster girls pretty much. A big plus for them being very fun to read/watch. Generic hentai level character growth for the characters that had more than a single chapter.
Enjoyment - 10/10 - A favorite. Read it several times and can still read it more without getting bored. Used images from the manga several time as sig/avatar/etc for forums.
Overall - 33/40 -> 8.2 out of 10 - If your a fan of vanilla hentai or monster girls, I would highly recommend giving this a shot, I'm sure you'll no doubt find several of the stories enjoyable, if not all of them.
