Yuyuko found Rinnosuke biggest shop and didn't get to eat him out of a job? Sakuya you ruined a great running gag. >.> Give her the job man and a early raise!
I don't think there's ever been a series of events involving Rinnosuke where he came out on top at the end, and I'm hoping we don't start now.
But with Yuyuko neutralized, all I can think of at this point is maybe he does something to get on Sakuya's bad side and ends up eating a few knives for it.
Maybe he'll try to pay her in pads? (not sure whether she'd be angry or overjoyed)
