DxD

Two anime-style characters in matching outfits stand back-to-back in a mirrored, kaleidoscopic frame with a radial blur effect, then the scene shifts to a heart-shaped frame with lace trim, revealing the characters in a different pose between two playing cards, followed by a rapid, blurry transition to a red-haired character singing into a microphone with the text "RIAS GREMORY" overlaid, and finally a swirling, abstract blur of green and blue light.
