I like the contrast of Raiden's fanart between her "would like to step on you" dominatrix and her girly sides.
Since one is Raiden Ei and the other her puppet Raiden Shogun/Baal created by Ei to act as the ruler of Inazuma. The "step on me" attractive dominatrix part is the Shogun since she's colder and sterner also she's programmed with directives by Ei. The "girly sides" is mostly Ei she's stern too but she's more emotive and sociable than the Shogun and she has desires, like her love for sweets and martial arts.
