From the game Genshin Impact; Puppet of the Archon of Inazuma (one of the regions of Teyvat); Raiden
Ei, the Archon of Inazuma who used
Raiden Shogun's body in order to move around; Raiden Ei lost her sister Makoto during the war against Khanriah; As she lost her sister, she became
cold and wanted to keep Inazuma thriving throughout eternity; Subsequently, she banned the use of visions since it may ruin her eternity plan (for example, Kazuha's friend got killed by
Raiden Shogun since he losing his Vison means that he might lose his ambitions); Raiden Ei created
Raiden Shogun for the purpose of promoting eternity; In her most recent story quest,
Raiden Shogun started to make Raiden Ei's movements in the puppet body difficult because Ei drifted away from her original plan ever since she canceled the Vision Hunt Decree; After they negotiated regarding Ei's new goal with the assistance of the Traveler (and Yae Miko);
Raiden Shogun (THE PUPPET) consented to let her freely use her body and roam around Inazuma.
