Kei (Blue Archive) Rule 34

Kei is a character from the mobile game Blue Archive, an artificial intelligence who first existed within the programming of the android Aris before taking on separate physical forms across the story. In her earliest appearances she resembles Aris closely, distinguished by glowing pink eyes, a pink or rectangular halo, and a sharp, tsundere manner of speaking. Later she appears in a wheeled robot body built by Rio, and also as a machine with an orange visor. Fan artists gravitate toward her pale long hair, hairband, and the contrast between her cool mechanical nature and her prickly, expressive personality. She is frequently drawn alongside Aris, Sensei, and other students, with emphasis on her halo, pink-eyed gaze, and blushing reactions that soften her stern demeanor.
