yes if you want to get the most out of your coupons

More like: wait for Fuku if you want to at least sniff what whales get, but forget about getting anywhere near heavy payers. This game reached point of no return months ago. If you allow your hopes to go up your only reward will be frustration. Let me tell you something: I play this game since December 2019 and while it was always unfair, there at least were some good events where you could get meta characters within semi reasonably time frame. Now? Almost every single meta character is paywalled and f2p events get the same stuff months after months after months. Sure, you can now earn around 10k coupons per month, but it's pointless when there is nothing useful to buy with them.
