The Raiden Shogun exists in two forms—Raiden Ei, her true identity, and the Shogun, a puppet created by Ei to act as the ruler of Inazuma in her stead while she meditates in the Plane of Euthymia. Ei has a more stern demeanor than the average person, she is notably more emotive and sociable than the Shogun. Unlike the Shogun, Ei has preferences, such as a love for sweets and her passion in martial arts. Due to her dedication to eternity, Ei is wary of the idea of change.
