The Raiden Shogun exists in two forms — Ei, her true identity, and the Shogun, a puppet created by Ei to oversee Inazuma in her stead while she meditates in the Plane of Euthymia. The Raiden Shogun is the awesome and terrible power of thunder incarnate, the exalted ruler of the Inazuma Shogunate. Her Excellency, who promised the people of Inazuma an unchanging Eternity. Shogun is cold and stoic, but Ei is a little softer and more humane and emotionally. Lives more than 2000 years.
