After you complete the main story the game just slowly drifts into being an P2W game. Example energy cost of stages gradually increases as you progress and the rates for characters are so low I pulled 10 10× pulls on Ludmilla banner and got no SSR character. I do like the story at the start but ive been spoiled by some people and said that the story turned to a bad ending and so that just made me lose all of my enthusiasm for the game and I just decided to finally uninstall it.
