An elemental for Maid of Heart tho. Would be persona from Megaten. Or shadow. Both, in fact. Thinking further... Umineko, which is related to Higurashi. Had goats that embodied the theories about tragic events on a certain island. Would they be the mind elementals or void elementals.

Interesting. I would say maybe they seem to embody Doom rather than Void or Mind if that’s the case?
