This fills like a filler episode since it merely confirmed something we all know all along, that Filo's going to be the next queen.
Pretty sure Fitoria's daddy was the previous shield hero, and part of why she didn't decide to kill them after all is because she's reminded of the old shield hero when she's around Naofumi, and so he now has 2 turkeys in his harem
The most interesting part is that scene after the ED, hope we finally get some answers next episode!
