Remember "Oreimo"? Remember "Kiss x Sis"? Man those were incest no matter how you look at it, can anime get any more far out than that? Unfortunately so, because here we have another anime related to incest. "OniAi", short version for "Onii-chan Dakedo Ai Sae Areba Kankei Nai yo ne"....which is ridiculously long. Well I'll start off by stating the similarities to other anime. "OniAi" is another romance/comedy harem anime....yeah, like we haven't seen enough of that. But you know, suckers like me like romance/cmedy animes, and as long as their funny, the girls are hot/likable, I'm all down for it. Fortunately, they are, or I'm just a mindless otaku, I don't know. If you like harems, you like laughing, you like hot girls, "OniAi" easily fits into your cup of tea, like most great harems.

I heard you liked some nyan

Most harems have pretty catchy songs to go with them, and "OniAi" is no different. The opening is "Self producer" by Minori Chihara (seiyuu of Ana), and its a very energetic song that fits very well with the overall theme of the anime. Its catchy as hell, and while it may not be among my preferred songs from her, it works well here and sounds great. The ending "Live-ru is LOVE-ru" by Liliana sisters, belongs to more more high pitched cutesy type of song, and while it is catchy to some extent, its not my cup of tea. I do like the starting though, because I always hum it when the ending theme plays.

Rating: 8.0/10

Its easy to dislike bad harems, but at the same time its hard to hate harems that are so damn good. Honestly, to me, harems only mean 2 things. The hotness/cuteness/likability of the girls in the anime, and whether or not it makes my ass laugh out loud. Romance is kind of a side thing, I'm too used to most harems actually not having any romance whatsoever, but of course, those who actually HAVE some romance in them will net me some extra like points. All the characters in "OniAi" on their own are already pretty damn cute, but the one that really boosts it all up is the little sister, because god she is one of the silliest anime little sisters I have seen and I LOVE IT. The rest are pretty awesome and funny as well but a little bit of them mostly scream as typical stereotypes. Not that stereotypes are bad, because tsundere is always awesome.

Well, f**k...

Himenokoji Akito is an average high school student living in the school dormitory. One day his sister, Himenokoji Akiko flies over to his high school, transferring there. She also states that she would be living in the dormitory as well. During their first night together, Akito remembers, his sister is a huge HUGE bro-con. That means she dotes on her brother and wants to have a romantic relationship with her. .......Whut. He remembers this when Akiko barges into his room with only a towel covering a body, screaming at him and asking him why he didn't peek on her when she was bathing. Akiko thinks that she is in a perfect situation since she is living alone with her brother, but things turn haywire quickly when 3 other girls join in the fun and start living in the dorm to keep a close eye on their sister-brother relationship. Here, we have a harem now!

There's no need to hype it up whatsoever, "OniAi" is just another harem you'd see anywhere with some really good characters. Many harem have good characters, but it takes an extra step to be really funny as well. Plus, whenever an anime tackles incest, you know some shit is going to go down. Just enjoy "OniAi" as it is, because even if you do not like harems, this shit is pretty funny.
