Back at the villa, Female Knight offers herself to be properly knighted by Hero in a sign of offering him her eternal loyalty, to which he reluctantly accepts.

To protect the Winter Kingdom from further problems, Hero comes up with a plan, by having Elder Sister Maid, disguised as the Scholar, handed over to the church just to be rescued by Hero in a later occasion.
