Height 24 cm One of the two Nukos found by Yuuya on the side of a road who proceed to live with him. Out of the pair of Nukos, he looks the most feminine. As Sasame is a boyish girl, the mangaka thought they'd make Kei a girlish boy who's easily embarassed! Kei now acts more and more like an older brother. She likes sashimi and miso soup, but only Yuuya's homemade. Her favorite spot is the bean bag chair.
