When you run out of focus, unless you use a pudding (or pudding replacement), you cannot fight again unless you back out of the event. I wish that it would let me attack again after ten minutes without going back to the home screen and then back to the event. Alternatively, you can go to the gacha machine, but unless you run out of tickets, there is no way back to the event from that screen.

Please fix this Nutaku. It shouldn't be hard. I can do weak/strong seductions the second my counter hits the appropriate time in EG, why not this event?
