>>15008789You have to pick an idol and use her in lives to reach the targets set by the game and climb the tower. The higher you climb the better your idol becomes, so you can get a basic one all the way to SSR+ if you are willing to grind. I didn't know the rules properly until the last one and picked idols whom I already had SSRs of.
Speaking of which, might you know if the SSR ticket becomes available at the start of each month? It used to be every four or five months I think but recently I've been seeing it much more often.
