It is so refreshing that the king and other heroes are... people, not the cartoonish evil creatures that often appear in manga. Prominence is both a good friend and bound by prophecy, which is good, the heroes feel sad for the whole deal but also know that this must be done... even that one that is all for the elimination of the Black Dragon, still knows that this is complicated
Who would knew that this is a better adult story than the "adult" stories that sometimes show up... I specially like their take on the "kicked out of the party" trope
