How can i unlock Miko?
You need to complete all the events (including the camgirls and the charity) and then the cave unlocks!
I need to unlock tham in 1 play though?
Yes, I mean the optional events.
does boss arch counts as OE, or its only streems,gym and charity?
Yes, every event not directly related to the pageant line is optional.
That means, both gym girls, the boss line (including the need to craft the mixture), the camgirls lines and the charity line.
