Namanaka is a hentai manga consisting of a few different stories with one being the main one (Chapters 2-8 and 12). In English, Namanaka means "No Condom Sex" so the name really gives no hints as to what's it's about, because really who uses condoms in hentai?
Story - 5/10
Leaving Chapters 1, 9, 10, and 11 out, the rest of Namanak is about a guy who one day comes across this tiny spirit named Oryou. Oryou claims that this guy (I forget his name and I'm too lazy to look it up since it's not on MAL and a he's a pretty bland pervert anyway) is
the reincarnation of her lover who was killed 300 years ago. The only way she can get her lover back as well as her own body (she's tiny and is once mistaken for a doll) is for this guy to go around having sex with girls. Oryou has the ability to tell which girls are the right ones (basically she's a whore detector) and then the guy has to do his thing from there. He's absolutely horrible at flirting but fortunately every girl is eager enough that it doesn't matter. From there, a bunch of sex happens as he makes a harem of about six girls.
Art - 6/10
The sex scenes are well drawn, but my main complaint is that most of the girls looks very similar (long dark hair, same facial structure, and big boobs). In the last chapter, it gets extremely confusing as to who is who. Even Oryou when not miniaturized resembles most of the other girls.
Character - 3/10
There is one character that I did really enjoy much more than the others. She was a model who wanted to do more explicit photo shoots as an exhibitionist, but her manager wanted her to stay clean and stick to swimsuits and other stuff. The main guy sees her flashing an old man and then goes and easily gets her to have sex with him. I just thought she was kind of creative, but unfortunately I can't say the same about the other characters:
- Childhood friend
- Sisters who look nothing alike
- Quiet girl who wants to break free from her parents strict rules (okay she was actually pretty good and the sex scene with her in a library as well but still I've seen similar characters)
- Oryou as well is similar to a lot of other spirits
The characters in the other chapters were also fit into existing archetypes and I've pretty much forgotten what they even were now. Also the main guy is just your stereotypical perverted male lead.
Enjoyment - 4/10
The sex scenes with exhibitionist and the girl in the library would good, however the rest kind of lacked and the last chapter was.... strange. Still, there's no incest (there's kind of rape but not really) and while one of the chapters has a shota, there's no loli. Also, despite the strangeness of the conclusion to the one main story in this, it was nice to see a happy ending for Oryou (as well as a good sex scene).
