The Raiden Shogun is unique as she is comprised of two beings in one body: Ei, the current Electro Archon of Inazuma; and the Shogun, the puppet created by Ei to act as the ruler of Inazuma in her stead, which also serves as her vessel. The Raiden Shogun is the awesome and terrible power of thunder incarnate, the exalted ruler of the Inazuma Shogunate. With the might of lightning at her disposal, she commits herself to the solitary pursuit of eternity.
