Nice video, and agree with Vemene, Momoko is the "real" Momo, not the young girl with pigtails
I am not that impressed with the song, but I really, really like this video for three reasons:
1. Miya is in a fairly silly mood all the way through, even in the Parisian flashbacks. I suspect that hanging around with Airi brings it out in her, and it's pure gold.
2. Momo is NOT in character as Momochi at any point in the video (and the pigtails make only a brief appearance during Paris sightseeing). That's a very, very welcome break. And it reveals part of what makes Buono! work -- they are all comfortable just being themselves in the smaller group.
3. Airi is racing towards adulthood almost faster than the eye can keep up. I can overlook the goofy nekomimi hairdo because of this.
Bonus reasons: more Jenga and pizza!
