After the graduation ceremony, Kirino arrives to pick Kyosuke up following the end of her middle school graduation, and both head out to meet Manami. As the group sit in the park, Manami becomes visibly angered upon learning of the Kosaka siblings' relationship and Kirino uses the opportunity to show off her victory in finally taking Kyosuke away from her.

After Kyosuke intercepts their final punches, they both agree that they could only ever communicate through their fists.
15. My Little Sister Is This Cute
2013 - Season 2
Kirino and Kyosuke head back to their hotel room to try and sort out their next move after agreeing that siblings cannot get married in real life. Kirino gets distracted with her newly bought eroge and finds that her feelings are too mixed to too concentrate on the game. Kyosuke then gives her a Christmas present which turns out to be the same ring she had asked him for the year previously, and ceremoniously puts it on her finger as a pseudo-engagement ring. Kirino reveals that she had planned on confessing to Kyosuke herself, but ran off earlier thinking that he was referring to his love for another girl. Having already given thought into their next move, Kirino shares this with Kyosuke. Sometime later, the siblings formally acknowledge their relationship to Saori and Ruri, the former of whom remains uncertain on her standpoint on the matter. After Kirino gets into her usual Meruru debate with Ruri, Kyosuke leaves to meet up with Kanako following her latest concert.

As Christmas Day draws near, Kyosuke ponders on Ayase's confession to him and makes a decision. The following night Kyosuke meets with Ruri and as they stand in the rain, he painfully breaks up with her by confessing his love for another girl. This brings Ruri to tears and she violently rips the notebook filled with the memories of their time together before cursing the world. The next day, Kyosuke asks Kirino out on a Christmas date to Akihabara like they did a year previously after tempting her with the chance to purchase exclusive eroge which she accepts. That night, as they exit the Tokyo Skytree, Kirino reveals her intention of going abroad once more upon her graduation and promises not to repeat her past mistakes.
