No, there are 3 April events from previous years (Easter 2017, Super Girlzz 2018 and Cameo 2019).
And if there are 7 girls available form villains it should be 2 from each of these 3 and 1 new Legendary girl as in previous Orgy Days.
But I'm really curious what kind of Event we will get at the end of the month then ...
