The setting is a little odd. Like how the demon lord just decides "yeah I'm gonna live with and take care of this guy" kinda out of nowhere.
Like I get she wanted a rematch and all that but the logical leaps to set all this up just feels a LITTLE out of place.
I've seen this same concept used before and done a bit better so this just feels a bit mediocre. It is kinda funny though so I'll stick with it for now.
