Hope's a magical girl, similar to Lily, Faith, Maddie, etc. Her monster companion Bucky is a magic-eating monster as well. She's also an empath herself, and actually has the ability to project emotions as well, so that might be interesting. I'm fine with both aether and echo sensing for her!

Nathaniel has a slight attunement to electricity, probably more like being connected to a powerful storm god than actually having that power himself. The shepherd's crown necklace he wears also allows him to cancel out attacks. I'm fine with both senses for him as well!
