Thanks for the chapter!
I'm really beginning to wonder if the princess has some kind of charm magic or something like the sister from Sevens. Considering her extreme arrogance and sadistic personality along with considering everyone around her no better than pigs why are so many people so loyal to her no matter what she does to the point of believing that what she does or wants is divine, all those her oppose her are the worst evil, and blindly cling to the belief no matter how selfish or evil she acts? Even after the torture and getting patched up Sandra will probably still loyally chase after hero for what he did to the princess thinking it's her fault for not protecting the princess and his for attacking the princess while glossing over the fact the princess' personality makes scum look saintly. Curious if best swordsman former acquaintance of hero or not, and if he blindly obediently hunts after hero, joins up with hero, or talks with hero before 'searching' for hero in areas definitely isn't at? Likely not a former party member as the party would have been executed around same time as hero due to being strong enough to fight the demon lord too unless are another blindly loyal underling who idolizes the princess no matter what. Might be a former royal guard who retired due to losing an eye and/or getting on in years. Would really be twisted if was hero's sister's husband. Guess will have to keep reading to find out.
