A tip for anyone starting out on DMM and is still on their beginner week, The guaranteed Gold ticket the game gives you as a beginner week log-in bonus has a 7.5% chance of pulling a 6* so if you're desperate for a 6* and don't want to pay, you can keep making new accounts to keep re-rolling that ticket. In both my Original account and alt which I don't really use, I got a 6* from that ticket pulling Iberisu and Anemone respectively.
