Shame that. All I know about the series is from what I've absorbed from this thread:
- Brother somehow ignores sister for years and discovers she's into eroge a bit too much.
- Other characters appear
- ??????
- The unforgivable ending.
Overall, I think I've walked away from this better off.
Its not a horrible show in terms of production and execution. Just the subject matter is out there and Kirino is a terrible bitch.
