"Kudan no Kuroneko" is made up of two main stories and a short side story to tie it all together. The first story is about a young cat god named Maya who goes out and tries to prove his worth by getting rid of an infestation of rats. However, he fails, loses the tools of his trade, and is taken under the care of Shinichi and his younger brother Yujiro. The younger brother falls for Maya's beauty, while Maya simply sticks around to get his tools back and go home. This first story is rather typical and doesn't have any big surprises. It is, simply put, a normal story with an exotic background. Yujiro is immediately taken in by Maya's unintentionally lewd poses, and Maya falls for Yujiro's persistence. The plot itself is weak and uninspiring, but the artwork and Mizukami's knack for strange humor make it worth the read. There is also a very random scene with rat tails being used in an unconventional way, but while it may make you pause, if you've read the story this far, it shouldn't make you stop reading it.
The second story is the back story of Yujiro's older brother Shinichi. This story was, by far, the more interesting of the two main stories, even though it was seemingly added on as a side story. The idea of a child being jealous of his father's lover is also an unoriginal idea, but leaving this love unrequited lent more depth to the story itself. Too often these types of stories end with one person forcing their feelings on the other, but this wasn't the case, and it caught my eye more for it. I find it more poignant if one character declares their undying feelings and actually sticks to it, rather than ending up with the son for the sake of sex.
The side story was short and filled with the author's own brand of humor, which was funny indeed. It sought to wrap up a few loose ends, but there were a few inconsistencies, and the story raised more questions than it answered. However, these things don't detract from the humor at all. I enjoyed the random explanations and the wacky ideas most of all.
Overall, I give it a 6 out of 10 for being interesting, but unoriginal. The first main story is a bit cliche and uninspiring, but the last two stories are definitely worth the read. If you can plug your way through the first mediocre tale, the second two will be your reward.
