Ahh, the heart warming story of the love affair between a 27 year old man and his 15 year old sister. Oh, wait...that's not heart warming, it's more like disturbing. Aside from that, this anime has a very slow pace, and as you might have already guessed, is a soap opera type anime. The artwork is somewhat irritating as most of the backgrounds look like they used the photoshop waterpaint filter on it, and the characters are drawn with very little detail to them. Just so you think I'm not being too hard about the older brother, little sister rorikon thing; I generally don't mind that sort of thing. Almost every anime has a younger girl who's in love with her older brother(like DC Da Capo), and usually they are fairly close in age and are actually are not blood relatives. Whereas, in Koi Kaze, you have the brother sitting in a corner of the bathroom smelling his sister's bra that he dug out of the dirty laundry basket. See? Slight difference.

If you're really into dull rorikon dramas, you should definately check this one out...otherwise, I wouldn't bother.
