It's kinda stupid that if you miss 2 days you fail the event, can we get some reasonable gameplay in here? It's not enough that 5 of the 6 event girls are locked in the pachinko the only one that is free is a pain to get if you can't login for 2 days, which is something very common on weekends. What a bunch of cheapskates.
If you don't want to give this for free at least let us refresh the event daily mission using premium currency.
