The Raiden Shogun is a firm believer of what she believes to be eternity — a place in which everything is kept the same, regardless of what goes on. She is honorable in her conduct and is revered by the people of Inazuma.
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. This puppet follows a set of directives programmed into her, which are extremely difficult to modify. The Shogun is cold and stern in personality, even callous at times; she is limited in emotional expression, has no likes and dislikes, and has no need for recreation. The Shogun thinks of herself as Ei's assistant and carries out her creator's exact will, unable to act on her own volition. If her usual functions are disabled, the Shogun becomes ineffectual. Due to limited protocols as a result of Ei's initial indifference towards anything other than "eternity", the puppet is able to be manipulated by external influences. For example, the Kujou Clanand Fatui persuaded her into initiating and maintaining the Vision Hunt Decree.
