Jun 26 2011 07:50 PM Onii-chan no Koto.....blew through this series all in one day.
All I can say is that this is one hell of a bad series. It started off fairly weak and mediocre with the cat essentially coming out of the bag in episode 1, where Nao learns she's not related by blood. For a show with only 4 manga volumes available and ongoing, I find it difficult for anyone to have reasoned an anime adaptation. The next couple episodes weren't bad when we were introduced to Shuusuke's childhood friend, Iroha...typical love triangle story. Of course, things all went to hell when they introduced a third, let alone fourth wheel in the story. Both of them were unnecessary to really drive the story forward as it made Nao and Iroha feel irrelevant, especially as Kondou began to dominate the story. All in all, there was no story. The show jumped around almost as if this was completely an anime original. While I encourage that, there was a lack of any sort of plot continuity.
Animation and art were atrocious for a ZEXCS title. This is a 2008 level quality with unsmooth edges, lackluster detail, and cheap facial expressions. I hope they do better in their upcoming summer title Itsuka Tenma no Kuro Usagi.
Music was not that great. Not sure what was up with that random change in op and ed theme in episode 7, but not that it improved the show in any way. Voice cast was rather annoying, particularly Nao. For Eri Kitamura (Yui from Angel Beats!) I never thought that she would be so annoying, especially since Yui was entertaining. Here, Nao is just straight up annoying. Marina Inoue as Iroha wasn't bad though.
Enjoyment? Bleh, I wasted my day watching this. It was definitely not good and would not recommend it. For something that could have been another "incest" show to continue the trend of OreImo and Yosuga no Sora, this was incredibly disappointing. Rewatch value of this show is obviously zero.
Overall, nothing to say. Move on and don't waste your time here.
Preliminary Score: 6/10
Final Score: 5/10
