The manga is written quite a bit different compared to the novel and not really in a good way. Doesn't help that the manga artist isn't really good either. Just look at how unerotic this art was, it's very stiff and doesn't look attractive at all. He was supposed to sink his hand into her breasts more and more as she writhes around, but here he's just hovering above for some reason while the rest of the art just looks unattractive as well.
The novel wasn't good either, but this was even worse. Sigh.
Also, in the novel, the author just mentions how she's actually a demi-human/human hybrid but he never actually mentions WHAT demi-human type she is. It's ridiculous because she clearly has the golden hair, tail and ears of a fox but she has this weird speech peculiarity where she goes "woof" like a dog and she also mentioned something about wanting to purr and be close to the mc, so she also has the traits of a freaking cat? This author never actually explains the world systems, magic systems, money systems or even anything about power levels, what levels does and about the characters. It's incredibly shallow, but I guess that makes it easy to write.
