Really? I disagree completely.
She genuinely tried to get kyousoke and kuroneko back together after they broke up to make them happy, even though she had feelings for kyosuke. She even wanted to leave for Europe so kyosuke coukd be happy with kuro or ayase. Its not her fault kyousoke liked her more than the other girls.
Of course she treated him in typical tsundere fashion for most of the series, but I think the ending clearly shows her love.
Check your outbox when you reply to someone. I didn't get any PM. It's likely you edit your post afterwards. In my original message, I'm not implying it was Kirino's fault that Kyousuke have feelings for her and burned the bridges with the other girls. It was his decision. I guess I was caught in how Kirino's character and forced ending ruin Oreimo rather than explaining how Kirino was a bad sibling. I admit I cannot bring evidence why. I still hold her as a bad sibling, but she's not the worse in anime. She was selfish at first, but her character has changed over the series. Looking back, it can be argued that it's everyone else's faults for prioritizing her over their selves. It's true Kirino helped Kyousuke seek Kuroneko. Kuroneko broke up with Kyousuke to help the two siblings get closer. I admit I was wrong. You did make a mistake. She didn't went to Europe. She went to America.
In the end, both siblings are messed up. Kyousuke felt jealous when Kirino said she was in a relationship with the one guy, but it turned out to be a fake. They couldn't accept that one sibling could love someone else.
