If the Angerme unit is doing pretty well, Kanon & Meimei wanting to call it quits, in such quick succession, don't make a lick of sense.
Hi! You must be new to this whole H!P/idol thing. (actually I know you're not, but statements like this makes it seem like you are)
Kanon Fukuda left when she did because she had been in H!P for 11 years
. She was one of the original Eggs back in 2004 and has spent a good chunk of her formative years in the idol spotlight. Her time has come, simple as that.
Meimi Tamura is leaving because, like Riho Sayashi, she has her sights on something more personally meaningful. Her heart has always been in acting--she was an actress before joining S/mileage--and wants to reach that next level.
In both cases, both Kanon and Meimi perhaps feel accomplished as idols and want to move on to something more substantial outside of the idol bubble. We can't really fault them for wanting to pursue their dreams.
And really, they're leaving Angerme in good hands. Calling it a "sinking ship" does a huge disservice to those carrying the torch. Do you not have much faith in Rikako, or Takechan, or Moe, or any of the remaining girls? Because personally I'm quite excited to see what they're capable of and how they plan to fill the void of those departing.
Trust me, as a Meimi fan I'm just as upset as anyone to see my favorite S/milangerme member leave the group, especially since I never got to see her or them in person (plus if I'm actually angry about anything, I'm mad at myself for not paying more attention to her as much as I thought I should be). But this is Hello! Project.
Veterans are always leaving (there's been at least one major grad every year since 2009), and new girls are always coming in. A lot of our current favorites would be either complete nobodies or waffling in obscurity elsewhere had previous stars not moved on and made way. The individuals and moments that drew me in when I first became a fan were long gone by the time I showed up, but I still managed to find value in what was left, and I'm still thankful as ever that I did...and I will continue to do so in 2016, because there's plenty of value to find in what's left right now.
It's funny...there was this Wota in Translation post recently wondering if H!P is doomed now
. It reminded me of all the pessimism that flooded the fandom back in 2009-2011, but at least such pessimism had weight to it back then. Doomsaying now just seems outright spiteful in comparison.
I mean it's still possible that like 6 months after their grad it just turns out that they had a boyfriend or something.
Even that kind of situation I can't really get mad about. I mean these girls are only human and need some real love of their own too.
