An anime-style illustration of two celestial beings, an elf and a demon, flying around the edge of a circular portal in space that is opening up to another universe. The scene should have a soft purple color palette with swirling patterns and ethereal lighting. Include elements like glowing energy effects on their wings, and make sure they look graceful as if floating through time and space.
