I actually got one girl (Noella) within my first ten clicks on the first day of the event, so I thought maybe they're actually going to make the drop rates reasonable for this one. I used every available fight click without spending kobans over the rest of the event and got nothing else. So much for that. I'll never spend kobans ever again if there isn't some kind of noticeable improvement in drop rates with this game.... On a related note, I've been banging away at a maxed out Roko Sensei for weeks now, and still have yet to pick up the third droppable girl (I still need Mavin). I've picked up all the other droppable girls, so I've got nowhere else to go anyway, but I wonder how long that quest will continue to be fruitless?
