Kirino Kousaka embodies the ideal student with equally entrancing looks. Her grades are near perfect, and to cover her personal expenses, she works as a professional model alongside her best friend Ayase Aragaki, who abhors liars and all things otaku. But what Ayase doesn't know is that Kirino harbors a deep, entrenched secret that will soon be brought to light.

At home one day, Kyousuke, Kirino's perfectly average brother, stumbles upon an erotic game that belongs to none other than his seemingly flawless little sister. With her reputation at stake, Kirino places a gag order on her sibling while simultaneously introducing him to the world of eroge and anime. Through Kirino, Kyousuke encounters the gothic lolita Ruri Gokou and the bespectacled otaku Saori Makishima, thus jump-starting an entirely new lifestyle. But as he becomes more and more involved in his little sister's secret life, it becomes that much harder to keep under wraps.

Oreimo is a piece of otaku media that I simply adore, even 14 years later after the anime release a lot of the weeb culture around it still holds up to this day.

Truth be told, I wasn't always an Oreimo fan, this is actually my second rewatch.
I first encountered it when I was 13, freshly new to anime. I hated it at first, I thought Kirino was a brat, Kyousuke being a weird obsessive sister freak, and I viewed the otaku culture around it as unpleasant. The only characters I liked were the main MC's friends (Ruri, Kanako, Manami, etc etc) but even that wouldn't ...

Mixed Feelings
An easy way to describe this anime would be the brother MC is essentially a punching bag.

There are also way too many tsundere's in this anime, even the dad is a tsundere, where most of them are more tsun than dere.

What this show has going for it is literally just the titles for each episode are funny and memes at this point. The rest of the show is honestly not the best for an enjoyable pleasant watch.

Specifically, both main characters brother and sister are not that great. The sister, Kirino, is violent and continuously hostile to her brother. While he himself feels like an ...

Absolutely disgusting incest "romance" story written by a japanese hick and pervert about porn addicted siblings that end up marrying. The author of it has got to be on some sort of list, as will probably happen to you if you rate this show high. Unfortunately, the first anime I watched a very long time ago and at a young age too. Only "saving grace" is the opening song and good looking characters, which is why anyone could find this show appealing. Even then their personalities are horrid. That is to be expected, as there is no plausible way to make a healthy and adequate ...
