Also, if it's indeed safe, I can really use any email I want when creating the account, even a non-existent one, and change it later when I get a good set of starting pulls? I already have Ouroboros SSR from the pre-registration gatcha, and got Beelzebub from my SR ticket, but Ideally I'd like to have 2x SSR, one summon and one Kamihime. Granted I could always get my SSR Kamihime later, when/if they introduce purchases where you can choose your own SSR (Japan received a few events like this), but I'd rather get one for free is I could.
