You're not going anywhere without paying an obscene amount of money. One of the lowest drop rates for a gacha game. Want an SSR angel? $50, upgrade it one time? $50 more dollars. Upgrade it again? $50 more. Upgrade it final time? $100. The game has good visuals but it only cares about you spending your money if you want to advance in the game. Highly recommend choosing some other game because this game is major P2W.
