I was playing a ‘guess the anime this opening theme is for’ with a friend recently and for some reason after going through literally hundreds of anime songs, this was one that really stuck in my head. Probably because I didn’t get it right and it really bothered me for ages as I knew it… either way though, who doesn’t love a ‘happy go lucky’ and catchy song, so I’ll take it as my SOTW. Here is Zannen Kei Rinjinbu by Marina Inoue, Kanae Itou, Nozomi Yamamoto, Misato Fukuen, Kana Hanazawa, and Yuka Iguchi, the OP for Haganai.
