I think it has something to do with the second trumpet. In traditional Christian angelology seraph (seraph=angel) is the highest rank and in the fifth rank in the Jewish angelic hierarchy.In Christianity I believe there are seven trumpets. Upon the first trumpet sound, hail and fire, mixed with blood, is thrown to the Earth burning up a third of the trees on the planet, and all green grass. And by the second trumpet sounding, it cues something like a great burning mountain that plunges into the sea and wipes out a third of all sea life and ships. A third of the oceans will become blood. (im too lazy to explain the rest of the trumpets so research it yourself!)  Also, trumpets are sounded by seven angels. Oh also in Islam the Angel Michela blows a trumpet and everyone dies, but later on is revived for the Day of Judgment.

My theory is... because Yuu holds onto the second trumpet Yuu is one of the (seraphs) seven angels, demon, and namanari. Anyways because the second trumpet is about the ocean and salt makes up whatever percantge in the ocean maybe he controls that. And Boom that's why he's called Salt King.
