I think that "My Koyori" was just freedom translation from HS, for me it sounds more like "That's the Koyori I know"... Just sayin'
I actually came to ask something, about Show By Rock... The episode in the beach was pretty nice but after that I thought "I will let it rest for 2 episodes" but idk, I don't feel like watching it now even though I like it, but what's more weird is how my friends stopped talking about it too and you guys... also seem to be avoiding it? With flip flappers, izetta, hibike and the other mahou shoujo talk, no one talks about Show By Rock and I was wondering, what's going on right now in the anime
