Well that sucks, I wait for Saffron tulip since I have the rest, though I would love some snowflake+lilac copies for upgrades. My Di Yu is cursed on skill up so not gonna bother with her

it looks like some people were complaining on mmosite about their Cepha codes no longer being valid when it switched to Di Yu. Makes me wonder if all the codes are good for all the girls, but only one girl at a time. Like would we be able to grab a code for Di Yu now, then use that code to get a Snowflake later?

Edit: Realized I was a bit unclear. The way people were talking it sounded like the Cepha codes were no longer valid for Cepha specifically, not necessarily completely invalid.
