>>492080512 cubes, 238 off sparking Suika

I can shave 50 off by doing a 10 GC roll, 188 off

5 free cubes from doing friend and card rituals from the event during the next 5 days, 163 off

1 cube from Sanae's shop during the next 5 days, 158 off

30 cubes from the login bonus, 128 off

Assuming the event stages are 15 in total, 45 cubes for clearing them in normal/hard/lunatic, 83 off

And then I finish the rest off with cubes from dailies and errands (around 15 / 20 every day)

Suika WILL be mine
