Story: 8.5
First off this story seems a little shallow with the "Don't accidentally date your sister!" plot device seeming like it won't get much done. However the story decides to throw twists in pretty constantly, doing a good job to keep you on your toes and doubting what you know. The liberal use of fanservice aside they actually create a desirable main lead and a reason for these girls to be interested in him. For a harem they also take the interesting route of starting him off with 2 romantic interests and then expand the cast, however by the end of the anime there are only 3 real competitors so it hardly feels like a normal harem, and that's a great thing. This anime is a Mystery Harem in the order, never letting go the fact he can't figure out his sister yet keeping it interesting by throwing in new characters and motivations. The MC gets in a load of stereotypical ecchi harem situations but unlike most actually has reasons to be in them. A good example of this is when the female cast believes he is 'gay' and decide to try to straighten him out through seduction. It gives us several scenes that you would typically see in an ecchi anime but actually bothers to make up a logical and fun reason to have it, and for that I thank this anime. Also tangent here, the MC in this can actually dance, I couldn't even of another Harem where the MC could dance well, this sadly is ruined a bit by the fanservice they smash in during this time however.
Art 6.5:
The arts not bad, but the animation is rather weak, the intro is utterly guilty of this feeling like its shot at half frame rate, I checked 3 different sources to see if this was an error but its really is just bad. It feels like they might have done the intro after making the whole rest of the anime. The show itself uses a lot of still shots with pan and zooming. The characters are drawn well enough (though the breast size seems to be whatever is convenient for the scene...) to be quite likable, but when comes to backgrounds and animations they're bellow average.
Sound 8:
The sound design of the anime is quite fitting, its not impressive like some anime (Fate/NGNL) which sweeps you off your feet but I never felt the lack of it or mixed feelings like I've gotten in shows like Mahouka Koukou no Rettousei. The voice actors do solid jobs so I have no complaints, only sad there are no standout tracks that make me have to go look them up (Date-A-Live) on the spot.
Characters 9:
How can I give a 9 to such generic characters? Honestly its because they act like they're supposed to. The cast are pretty stereotypical character models for harem females for the most part but they act like it. They are over the top and do stupid things but doing so in character makes them much more likable, I wouldn't mind if they were more complex characters. However that's what gets you a 10 in my scores, so despite the fact that I really liked them I had to dock them a point for not having too much to them. I will say this is the first time I've been interested in 3 female leads in a harem. Normally only one will stand out, two at best but possibly because they don't dig too deep with them they're all fun and I don't harbor strong feelings towards the one I want to win like normal.
Overall/ Enjoyment 8:
I rate animes off my enjoyment of the world. I'm a bit different from others in that I like the world created to be intriguing enough to want me to learn more about it. This anime made me go check the wiki for info about it after I finished, that automatically gets an 8 from me as I wanted to learn more about. Sadly very little of the manga is translated and none of the light novel, however the twists keep coming from what of the wiki I read. This series really suprised me, while I wouldn't call this a masterpeice it was well worth my time and its a shame so many will give up on it after reading these reviews
