After Kyousuke and Kirino graduate from their respective schools, they are confronted by Manami, who has come to fight Kirino for Kyousuke. She comes right out and calls their romance disgusting and threatens to tell their parents,. After several blows are exchanged between her and Kirino, Manami confesses to Kyousuke, who turns her down, saying Kirino will always come first. She slaps him and leaves. Kyousuke and Kirino get married in a chapel and exchange a kiss, and then go back to being normal siblings, as they decided on Christmas Eve.
We knew Manami was going to be upset when she learned about her betrothed going out with his little sister, but we had no idea she was going to be such a badass in this final episode. She beats Kirino up and pours a big ‘ol glass of cold water all over the pair, telling them all the stuff no one else had up to that point. Her scolding falls on deaf ears, not just because Kyousuke had chosen Kirino, but because unbeknownst to Manami, their romance was always going to be a temporary one, and just wasn’t quite over yet. What Kirino whispered to Kyousuke was that once they graduated, they’d put their romance to an end and continue on as proper siblings.
This begs the question: if that romance was temporary, what purpose was served by having Kyousuke burn his last bridge with another girl? Why break so many hearts to confirm to Kirino that her brother would destroy his entire love live six times over if it meant just a few fleeting months as her “lover?” Was it really worth ruining so many of his friendships to have a pretend wedding and a chaste kiss, only to drop it all right afterward? The extensive fallout really doesn’t seem worth it, even if the conclusion (they didn’t actually become lovers) was a foregone conclusion (this isn’t siscon eroge).
So the series ends on a logical, if somewhat awkward note, having backed Kyousuke and Kirino into a corner and callously discarded legitimate love interests for a fling that didn’t and wasn’t even supposed to last. But while Kyousuke’s unwavering devotion to fulfilling his little sister’s selfish whims often frustrated and even maddened us, we won’t deny we were also greatly entertained and at times downright moved by his many exploits over the last two seasons.
