6th/9th gen: A: Eri/Eripon, B: Reina/Kanon, C: Sayumi/Mizuki, D: Riho/Miki. A took a little to grow but I love them strangely insanely much, however it goes without saying that Eri will always be... well. Miles ahead and meters above any- and everyone ever. B is a huge instant love but they don't move much except for some days but I still love them all the same. C came off as dull and boring but before I knew it, I love them to bits. And D are so amazing and talented I can't help but loving them, and the more I see the more I realize I love this generations even more like... idek.

10th is a bit more different though. As Kudou is the first MM member I actually dislike, I really can't put her along with anyone. No such experience before. >>; Will do with 8th gen and the other three though.
E: Haruna/Aika, F: Ayumi/Junjun, G: Linlin/Masaki -- E took/is taking some growing but I really like them the more I get to know them. F were instant love and just continues to be more and more awesome. G was awkward and honestly a bit of a dislike (muchos for Masaki during the auditions lmao) but the more I see and the more they open up the more awesome I see and it's just.. *_*
I really do love 9th and 10th gen over all though. So much. *_* 9th gen is definitely becoming to be my 2nd favorite generation ever. Which is so strangely awesome.
