Sakine Meiko is notable for being a reflection of MEIKO. She is meant to portray a younger version of MEIKO, as seen in "Mellow Yellow". She has light brown hair styled into a teased bob. She has side swept bangs and her eyes are brown and large, done in a style similar to illustrator Kei. On her left upper arm is the black mark "00 MEIKO", its significance is currently unexplained, though it may likely be homage to Sakine's mark being CRV1.Her top is red-orange-colored, sleeveless crop top with a black hem. The rest of her attire follows the same color scheme, with a red choker and frilled skirt. Sakine wears long, red-orange, fingerless gloves with computerized print. On her skirt is a white belt, along with another deep red belt that hangs on her left side. She wears light brown boots with white fur trim, and has black headphones.
