I believe I've read quite a few times that Gem Gatcha only houses a couple R KHs at once, or did I misinterpret something? As for SSR KHs - I haven't gotten one so far, I'm a fairly new player as you might be able to tell by my questions. I started just before the Crom Cruach event and have just read a couple threads on the forums to familiarize myself with the game.
