Due to the underrating I see from most, I have to tell you first: this is NOT seinen.
I think the best age for this is around 15-16, for me it was not really an issue as I was watching the original series in my youth.
This is the best western middle age oriented fantasy you can find, no contatgion with ninjas, shamans, etc.
And the two japanese characters (Popp and Merle) are very well mixed with the others.
I think the writer often use Popp as a pivot character exactly for this, because he represent the typical target of this series, physically almost a fully grown man but inside still a young and immature teenager.
