Raiden Ei, also known as Beelzebub, is the true Archon of Electro and the ruler of Inazuma, one of the seven nations of Genshin Impact. For centuries, she acted as the shadow of her twin sister, Makoto, and after Makoto's death, she assumed the role of Shogun to protect Inazuma, adhering to her ideal of Eternity. Personality Ei is a reserved, serene, and extremely disciplined woman. Her way of thinking was shaped by the loss of many loved ones, leading her to believe that change only brings suffering. Therefore, she sought to preserve an unchanging world under the concept of Eternity. Although she often appears cold and distant, she actually possesses a kind and curious side. Over time, she learns to better understand humans, accepts that change is a natural part of life, and decides to become a ruler closer to her people. She also enjoys sweets and has a great interest in martial arts. Lore Five hundred years ago, Ei and her twin sister, Raiden Makoto, fought together during the Archon War. Makoto became the official Electro Archon, while Ei acted as her kagemusha, or protective double. To the world, they were both known simply as Shogun Raiden. After Makoto's death during the Khaenri'ah Catastrophe, Ei inherited the leadership of Inazuma. Fearing the loss of everything she loved, she created a perfect puppet called Shogun Raiden to rule in her place, while she remained meditating in the Plane of Euthymia, attempting to achieve absolute Eternity and prevent the erosion of time. Her quest for Eternity led to the Vision Hunt Decree, a decision that sparked great conflict within Inazuma. Thanks to the intervention of the Traveler and Yae Miko, Ei understood that true progress cannot be halted and decided to change her way of ruling. Appearance: Raiden Shogun's (or Narukami's) default outfit is a modified kimono inspired by traditional Japanese fashion, distinguished by its dark color palette and rich ornamentation.

She wears separate sleeves, not attached to the kimono, that originate at the biceps and cover the entire forearm, displaying a gradient color that fades from a dark purple at the top to a lighter violet at the wrists. A wavy pattern with gold prints mimics flowing water or traditional Japanese clouds. Wide, stiff gold trim adorns the cuffs. A guard covers the back of the hand and is fastened with a loop around the middle finger. Finally, a black and gold samurai-style armor plate (sode) is fastened with red cords and draped over the left shoulder.
