In my own opinion, I think EbiMasu really became successful with or without Hokuto's influence in their 5-year career. For me, before Muscats came, Sola, Yuma, Acky, and Rio became household names in the AV Community. And that would be a possible reason why Muscats is soaring high. Put aside Hokuto and insert another factor why Muscats is successful for their 5-year tenure: US.
I always watch the Muscats' PVs on YT and reading the comments, particularly in Oecura Mambo and Watashi Mambo. My fellow Filipinos asked, "Where is Maria Ozawa?". I said, "She became a Muscat for a short while" (Our country is both an Ozawa Country and a Sola Country). I think if Miyabi stayed, the Muscat's fandom will spread throughout SEA.
When it comes to Margarines, I think they should be given a chance. I mean, Aino give them the Muscats' dream to perform in Budokan...and she wants to see it fulfilled. Even I wanted to see it fulfilled.
Call it a "Punch to the Moon" but if Maccoi didn't cut Muscats' tenure while in their prime, I guess they will soar more...and it is because of us. If some one wanted to stay and be a Senpai to the new members, that is fine. If they wanted to graduate, it is also fine.
Speaking of which, in my opinion, Risa graduated, but not because she switched sides from Hokuto to SOD. Mihiro graduated because her retirement was draw near at that time. KONAN graduated because she wants to move to a greener pasteur (and creating an unforgetful rivalry between SDN48 and EbiMas). Risa graduated because of personal reasons. In my opinion, the SOD-S1 rivalry is not the reason why. If I wanted to ask her why, I will not ask. I just let her because that is her decision.
For me, EbiMas is not just a bunch of girls, mostly AV Idols, who sing. For me, they just love it. Bonds where created there. I mean, for me, if I choose between buying their DVDs and a ticket to their one-time reunion concert (another impossible dream), I would choose the latter.
Sorry if I get carried away here. When I hear "Album", I almost cried to the point I ask internally, "Why?"
