Sei Shounagon's Noble Phantasm CG. Use only on works that directly imitate the CG, commonly with a sunburst background and the character doing a standard double v.
DO NOT tag Sei Shounagon if she is not present in the image or if a character is not wearing her outfit! This tag is sufficient enough to reference the meme. Also not to be confused with the similar Hoshino Ai's pose as Ai's uses an upside-down double v.
