I'll start with the art, because the original artist Mao retired after completing chapter 20 and their replacement... I've read comments that say 21 onwards is a severe downgrade. The quality and style—aside from having really over-the-top lewd fanservice and some nudity—is actually really appealing. I'm at chapter 19, so I can't confirm nor deny the opinion of the new art just yet. Definitely not for kids, regardless. Now to how I originally wanted to kick this review off:
On one hand, the plot so far is an excuse (decent if you excuse how quickly they all fall in love) to gather a harem. On the other, the premise and world building show potential that, if the story as of chapter 19 stops adding new harem members for the main character, develops them, and becomes about what the lesser hero and his harem does while the bigger hero is out saving the world, this could be a really cool story.
This could be a tale about the local hero keeping the home region safe while the expeditionary hero kills the demon lord. I hope this is the direction it takes.
But I worry that instead of taking advantage of such a refreshing direction and the foreshadowing that both the brave and the hero do great things (the two are separate concepts; I'll explain next paragraph) that the hero turns into a villain. I really hope that isn't the case.
One head scratcher for me is the confusion in the terms "brave" and "hero". Believe it or not, Japan has the words/symbols for both, and they are different. The "brave" (translation, not a perfet fit in English) is something like a great character whose motivations and morality may vary greatly. The "hero" (a much better translation as it fits English better) is a character of destiny whose morality is good and motivations are noble or altruistic.
Perhaps it's the current translation I'm viewing, but the story literally swaps the two. The expeditionary hero who is chosen by the gods and fights for the will of the people is called the "brave" while the brave who fights for the sake of his women is called the "hero".
Oh well. Anyway, this story could be refreshing, but gives off some vibes that it will ignore what makes it special to do something either generic or bad.
