Oh wow, I have to admit, I never expected to enjoy this anime so much!
This series' full name is 'Onii-Chan Dakedo Ai Sae Areba Kankeinai Yo Ne!' Oh how is loosely translates in English, 'It Doesn't Matter If He's My Big Brother, As Long As I Love Him, Right?' This anime was adapted from the light novel series of the same name written by Daisuke Suzuki and the artwork was by Gekka Uruu. Now the author has written another light novel series before writing this one which was also made into an anime. “Goshuushou-Sama Ninomiya-Kun” And like this series, that one is also an ecchi harem series but it doesn't have the incestuous love element that this series has. I haven't seen Goshuushou-Sama Ninomiya-Kun but if it's anything like this series then I'm sure I'll enjoy it!
To tell the truth, I've only read the first 3 of the 8 light novels that are out but those are the only ones I could find with an english translation, and even then, I was going to try my hand at reading the original Japanese novels but I couldn't find them anywhere online so I just had to settle for the first three novels to learn from. I've also read the manga adaption but once again, I didn't have much to read since there were only 5 chapters out online.
Now I feel like I have to warn you right now if you want to check out this anime that it's rated 16+ it's got plenty of ecchi moments and there are scenes were characters get completely naked but there's censorship around the really naughty bits. And if you're really close-minded and absolutely hate the idea of an incestuous relationship, then I don't suggest watching this.
Story- The plot for this anime is pretty simple. These incest-related light novel series seem to have plots like this. But even though the plot is pretty simple, that doesn't stop this from being an enjoyable romantic comedy anime. Through the whole anime, nothing much really happens, it's just comedy for comedy's sake with a bunch of fanservice thrown in. But for what it's worth, the plot may be simple but if you're into comedy anime or slice of life anime, or even enjoy a good harem anime series then you're going to enjoy this.
Art- The animation work on this anime was done by Silver Link, they are best known for animating the “Baka To Test' anime, and I have to admit, I really like the way they animated this series. One point that I really liked was that the eyelashes were colored to match the character's hair colors, which I think is a little unrealistic but it does bring a nice bit of depth to the character's eyes and made them really pop to me. I also loved the little bit of shine that they added to the character's skin, even though that's a common trait to find in ecchi anime like this.
Sound- The opening theme for this anime is called “Self-Producer” and it's sung by Minori Chihara, who is the voice of Anastasia Natsuhara. And I just love how much energy is in this song! And considering that there isn't a full English translation here online yet, I'm going to be working on translating it into English the best that I can even though I'm not 100% fluent in Japanese. And the ending theme song is called “Life Ru Is Love Ru” and this is sung by the female cast of the show, the main 4 female characters sing this ending song. And once again, this song is just full of energy and is just addicting to me and I can't get enough of it! The voice cast are all pretty well known in the anime community and they all did a wonderful job with voicing the characters for this anime! I found no faults with them here.
Character- All of the characters in this anime are all vibrant and interesting to say the least, these characters all have their own quirks that make you love them, and I had no issues with any of them, which is rare since I tend to find an issue with every any character I find in an anime like this but not this one and I commend the author for creating such wonderful characters!
Enjoyment- This anime had a lot of good moments, moments that made me go 'aww' or made me laugh, this anime was very enjoyable to me and I was looking forward to each episode. And one of the quirks about the episodes is that we see focus on pretty much every character and no one is left out, which i find rather hard to balance with harem series like this with more then one female lead but this was executed really nicely, the jokes were all funny and the ecchi moments weren't too over the top either. Overall, I enjoyed the anime through and through and didn't get bored at all and was thoroughly entertained!
Overall- I would recommend this anime for anyone who loves the slice of life genre like I do, or anyone who loves comedy or fan service or even ecchi anime like this, but like before if you don't like incest or don't like ecchi and are very close-minded then I wouldn't advise this anime, but if you can get past those little details then you'll find a very funny and enjoyable anime out of OniAi! I would especially recommend this to anyone who loves the romantic comedy genre of anime. I honestly don't see why this anime gets bad reviews, I've seen my share of bad anime before and this one wasn't one of them!
