Raiden Ei
Raiden Ei from Genshin Impact is one of the most famous and loved characters in video game history. At first, she is a scary enemy as the Electro Archon of Inazuma, but later she becomes a very sympathetic character. She is the real mind behind the Shogun puppet, and she rules her country with an iron fist in her search for immortality. Her change from a cold, unyielding ruler to someone who is sad and having trouble with the modern world is just brilliant. It completely changes what you would expect from a character of that level.
Ei's character design is a work of art in every way. That beautiful purple kimono she wears is the perfect mix of traditional Japanese style and battle-ready mobility. Her long, braided violet hair, striking purple eyes, and famous sword pull make her impossible to forget. She is the best gap moe waifu when it comes to personality. The Shogun acts like a cold-hearted kuudere, but the real Ei is surprisingly quiet, loves sweets, and is terrible at cooking. The fandom fell in love with her because she is so different from a lightning god who can split islands in half and a socially awkward shut-in who just wants some dango milk.
She rules the fanart scene when it comes to wallpapers. Artists love to draw her in action poses with her glowing electro energy and her signature blade. There are also a lot of beautiful atmospheric pieces of art that show her looking sad under cherry blossoms and cute slice-of-life pieces that show her enjoying desserts. Ei always delivers, whether you want a super cool desktop background or the best waifu material for your phone.
