Has anyone in the same unit faced each other more times than Natsupoi & Yunamon

There's a possibility that Natsupoi & Yunamon will face eachother in next round of the Cinderella. If that is the case that would be their fourth singles match against eachother and I think 10th match against eachother overall. So my question has anyone in the same unit faced eachother as many times as Natsupoi & Yunamon?
