Thanks for the chapter!
Hope this guy actually tries talking rather than assuming just because MC has slaves is a bad guy who's tormenting them. By the way, how do you set up spoiler tags? Is it like spoiler and /spoiler in [] like
? Anyway, that self-proclaimed hero is not an riajuu which he'll explain later.
@macarroiz Blue balls is a reference to a man being aroused for extended periods but unable to vent his pent up lust for various reasons. For example, the nun might be (or hero thinks she might be if assumed and hasn't asked) part of a strict order that forbids sex with anyone other than the wedded husband or prohibits sex entirely while part of the order. So hero could have blue balls being with several cute girls but can't relieve himself if always around one member of his party and afraid they'd look down on him if catch him.
