I created an account on DMM to check this out (this was much more difficult than expected since the register button literally didn't work in my PC browers). Unfortunately, it looks like you're not given any Gatcha credits to start with, so rerolling looks impossible. Also, an inside source says the game won't be censored. At worst, any references to age will be removed. The game will have mosaics though since it looks like this will be managed from the Japanese side.
