Kirino used to adore her big brother, but as he grew older they grew apart, and as she strived to surpass him, he stopped seeming as amazing as she once deemed him. She suspects Manami’s influence, but Manami tells her the amazing Kyousuke Kirino loved never really existed. Kirino made a friend in Ayase through modeling, and also discovered siscon eroge, which she had to keep a secret, until it grew out of control, and she finally had to ask her average, unremarkable brother for advice, and he performed his brotherly duty admirably, if not as cool and confidently as he once did.
The last episode of Oreimo for some time serves as a prequel to everything we’ve seen thus far, and documents the evolution of Kirino’s feelings for her brother, leading up to their current, cordial relationship. Basically, the younger she and Kyousuke were, the more amazing she thought he was, and the more he was willing to spend time with her. But he eventually outgrew that arrangement before she did, leading her to aim to surpass him. So we can imagine her disappointment when Kyousuke devolved from the driven, talented, cool brother she once knew into a lazy, unmotivated layabout. The person who drove her to become better than she was had gotten worse. Since the very beginning, it’s been clear that Kirino is a big, hopeless otaku, but this episode finally confirms why: she was seeking the ideal brother Kyousuke no longer was.
She shunned her real brother in exchange for the brothers in the games she played, who would always do what she said and be with her no matter what and be just as amazing as she wanted them to be. But they were no more real than that youthful ideal of her real brother. Kyousuke is and always has been Kyousuke, and regardless of how much he disappointed her, he was always going to protect her, as he does when he passionately defends her hobby to their fatheer. Now Kirino is mature enough to realize that Kyousuke may not be perfect or even particularly cool, but he’s her brother; her only brother. He’s all she’s got, and he’s really not all bad, as big brothers go!
