sigh. so, author had to add 2 overused tropes. One is ye ole standard Japan self-insert (always as a 'far east island'... can't you be a 'far south peninsula' for once?).
2nd is sex slaves, yay... Too bad it's not an isekai, or MC would've met her first and gone to the dungeon to earn enough to buy her. ... can't we just not include slavery, especially when at no point until now was it included as a part of Orario. The stuff with Soma was close (basically born into debt slavery, except could leave but then would be falna locked), but at no point did they just buy people or kidnap them into the familia.
