Kureiji Ollie from Hololive 4K HD Wallpaper

A close-up anime-style illustration shows Kureiji Ollie against a solid red background. She has striking red hair with pink and purple highlights, and her face is split with grey skin on the left and a stitched seam down the middle. Her eyes are heterochromatic: the left eye is a swirling mix of colors with a diamond symbol, and the right eye is yellow with an 'X' pupil. She has sharp teeth and a wide, unsettling smile.
