I never liked this arc. The rich girl really being poor is such an overused trope, the best thing about the whole arc was when Keima declared that winning her over would be super easy. That and Elsee in a completely out of place maid outfit.

Worse is that the rich girl's VA really annoys me. She's great when she plays quiet girls like Noel and Korone, or bratty little elementary schoolers like Murasaki (Kurenai) or Marika (Ai Baby), but when she starts to get all emotional like here or Mina Tepes, her voice sounds like nails on a chalkboard. She still sounds like an elementary schooler, but at least you know she's supposed to sound like a little brat.
