So to summarize...fires are you, me, Axel, Valvatorez, Milla, and Ookurikara, and lavas are North, and Minato. That's all eight of us, amazingly. Waters...Shirasu and Shess, with Emma, Lili and potentially Feral having ice. Earth we have Naminé and Cinnabar with plants. Four I believe is earth as well. Akane is Air, though I don't know what branch.

We know that our deceased have all been water, air, or earth-aligned. I believe Hisoka was plants, we know Swift Wind was also water.

The rest are unknown to me.
