Animation:
As a web release, this is probably similar to Haiyore Nyarlko (the first web release). If anything, it looks even more plain (and the male character even less palatable). The show uses extremely simplistic backgrounds and the characters look as if they are literally from your Sunday newspaper comics. Don't expect much in terms of animation of movements as well. The only thing that you'll see moving a lot is the blood from the brother's nose.
Sound:
There isn't much in terms of OPs/EDs. The BGM sort of fills the slots with a slightly suggestive opening track, an unbelievably annoying rising melody between episode segments, and an ending track that sounds like it's straight from a handheld dating sim. There aren't very many BGM pieces given the short length of the show but be prepared to hear certain tunes over and over again- and I don't mean the good kind of tunes.
I'm quite surprised that Mai Nakahara agreed to the role of Saipuu, but in any case there isn't much character development going on so the voice work is less important than usual. Nothing out of the ordinary in this segment.
Story:
The entirety of this show is about our dear brother getting into ridiculous situations due to his sister's crush on him. She often pulls extremely seductive moves on him while acting all innocent like she doesn't know better. Though this quickly grows tiring, the director decided that abusing this pattern repeatedly throughout twelve episodes was a good use of the budget. Each tiny episode is further divided into miniscule segments that make Nichijou segments seem like they last an eternity. Each segment is pretty much self contained so don't expect much in terms of development of any kind.
Character:
Saipuu is an innocent and busty girl who likes her brother who is your typical, useless lead that doesn't do anything other than get morning wood and bleed a lot. The show does occasionally throw in some additional characters but they don't really contribute much to the mix. As mentioned before, expect some situational ecchi humor but no development. I'll bump up the score a bit since I can't really expect full character expositions considering the series length.
Value:
If you have absolutely nothing to do and have a bag of popcorn chicken ready, watch something else. I can't really recommend this to anyone other than closet perverts and softcore fanatics.
