Damn. what a Goddess. She's THICC and she uses a whip too??
I'll let her Whip me if I misbehave. lol
I could go as far as ask about who you are talking about, Raikou, the actual character in this image, or Murasaki, the character she's cosplaying as, but I'll go ahead and assume it's Murasaki, which then I must say, she's a novelist, she uses books, scrolls and words in her attacks, no whip here, just an umbrella.
And if you are actually talking about Raikou, she uses (mostly) a sword.
