Raiden Shogun is a puppet that was created by Ei to rule over Inazuma. Ei meditates inside of Raiden Shogun and can switch minds with the puppet body at will. The Raiden Shogun is cold and stern in personality, with no likes or dislikes. Ei is much more expressive and emotive than Shogun. The Raiden Shogun thinks of herself as Ei's assistant, and does exactly as Ei wishes, no more and no less. Ei is a firm believer of what she believes to be eternity, a place in which everything is kept the same
