In the first half, Yozora looks back on when Kodaka first transferred. She recognized him instantly, but he never remembered her, and she was scared to be the one to bring it up. It wasn’t until her hair was singed and she had to have it cut short that he recognizes her, and even then, they can’t just go back to the way things were ten years ago, when he thought she was a boy. While they aren’t the friends they were, they’re still…something.
Haganai resists the urge to close with yet another beach episode. We can be thankful for that, at least. But we’re still a little disappointed that everything basically went back to the way it was. We should have expected as such; ten years is a long time, and considering Kodaka never knew Sora was a girl, it’s understandable it wouldn’t even occur to him that Yozora is Sora. All I know is, I was never in doubt as to the gender of my childhood friends, so I can’t say whether I wouldn’t be just as clueless as Kodaka in his situation.
Of course, this episode had to include everyone else, and unfortunately that meant one last unfunny Rikagasm and forced cosplay, because now the club can’t recognize Yozora with short hair. Sorry, but that’s ridiculous. She looks exactly the same aside from the hair; in the real world, it would be impossible to mistake her for a boy. They don’t have the ten-year excuse. The series is left very open-ended, with Yozora continuing to run the club, and her and Kodaka’s future together left ambiguous. Which pretty much sums up our feelings for this series as a whole.
