I suddenly had a flashback.
My introduction to H!P was Tabidachi no Haru ga Kita, and out of everyone, she really stood out to me in the PV. She was cute, had a nice voice, was really smiley, so she quickly became my favorite in the group (up until Murotan joined, but she was and still is hands down one of my favorites in H!P).
When she graduates, it'll be around 3 years since then, and I'm glad I was a fan for approx. half of her being a member in the group.
I'm just kinda surprised at the timing since not even a month has passed since Kanon left. But yeah, like others said, Kanon leaving, and maybe Riho also (who joined H!P approx around the same time Meimi did) probably aided in the decision, setting an example of leaving to pursue their dreams.
It's gonna be so different not hearing both Kanon and Meimi's voice, they have quite distinct voices, as well as a ton of lines, but I wish her good luck with her pursuits!
^^ Holy shoot o.o I've seen/heard clips but it never gets old, it's still astonishingly amazing to watch, and I really hope she gets to perform more outside H!P.
