There is blood but is mostly purple, some red blood is seen. There is fighting violence in the film.

Martial arts violence thought the entire movie with Spiritual powers.

When Lord Yakumo tries the extract the Power Sphere from Botan, a little a mount of blood come out of her mouth. Generally, slightly lower than PG-13 violence since most of it happens to demons.

None.

Some intense scenes with Botan and Yakumo.

The demons may be scary for young kids.

Yakumo uses his power to throw Yusuke into Genkai's temple.

The following is about religion: There are references to Demons/God/Gods/Spirit World (sort of like Heaven), Demon World (sort of like Hell) and The Nether World (sort of like Limbo), references to Buddhism)

The scenes where Lord Yakumo tries to extract the power sphere from Botan can be frightening. But most of the violence happens to bad guys, so nothing terrible. (?!)
