Given Kirino's success and popularity, Kyou is more than a little bemused when he ends up finding an anime DVD in the hallway of the family home after accidentally bumping into his sister, and any confusion becomes even more intense when he finds an 18-rated eroge inside said DVD case. Surely it can't belong to anyone in his family? After feeling out his parents and getting the expected answer, it appears that there can only be one culprit, and lo and behold before he knows it Kirino has all but confessed to owning said product.
What Kyou isn't expecting however is that his sister is in fact a massive otaku, with a huge hidden stash which she drags him out of bed to show him in the dead of night. Even worse, her obsession is with eroge involving little sisters who love their brother, although thankfully for her brother Kirino's interest is more in the little sisters and how cute they are themselves. So, before he knows it Kyou is dragged into Kirino's rather odd little world, setting the scene for the series to come.
|It's a wonder Kirino's hobby wasn't discovered from the amount of time she must have spent downloading patches for 0verflow games...|
This particular premise almost sets the show up as a bit of a Genshiken wannabe, and although I can't see it reaching anything like those heights there is room for some decent comedy and a story that we can all feel some familiarity with - for a first episode, it was certainly neither "shit" nor "pathetic", that's for sure.
