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?
IMO Demon Slayer is one of the more kid friendly animes out there (of its genre).
If you dislike the gorey scenes like decapitations, but are fine with only blood, Saint Seiya is a great classic – five boys fight to protect the goddess Athena from the forces of evil. From memory, there are no scenes of dismemberment, and sexual fanservice is pretty much nonexistent. Lots of magic blood flowing out of bruises, though.
Saint Seiya Omega is a newer, even more kid friendly sequel. There's still some blood, but it's definitely muted in comparison.
