My daughter has picked up an interest in Demon Slayer, however having watched a little I think it's too violent/mature.
I'd love to foster her interest in these things, by trying out an alternative anime that hits similar notes while being more age apropriate.
Any recommendations?
Eh, Hunter×Hunter gets quite heavy. The Hunter Exam arc gives a slightly lighthearted impression compared to latter parts, even if it does not have a ton of explicit gore, it is violent.
The series is sorta violent even before Chimera Ants, where the evil-ness is kicked up to kitten-kicking, puppy-eating, "Sauron and Voldemort would hold a villain intervention because it's too edgy", gorey mess. Before that it was still relatively edgy shōnen but it seemed to take a slight turn there.
