The Shogun exists in two forms: Ei, her true identity, and the Shogun, a puppet created by Ei to act as the ruler of Inazuma in her place while she meditates on the Euthymia Plane. While Ei is still relatively stoic compared to most people, she is noticeably more emotional and friendly than the Shogun. Unlike the Shogun, Ei has things she likes and dislikes, such as a fondness for sweets.
