HMX-17a Ilfa, designated the newest model in her series, is an experimental maid robot developed by Kurusugawa Electronics. She runs on the "Dynamic Intelligence Architecture" software designed by Sango. Identified by the alias "Ic-chan," Ilfa possesses a slim, pale frame standing at 153cm with measurements of 85-56-82. Her teen-like appearance features medium breasts, straight blue hair cut shoulder-length with blunt bangs and side locks, and distinctive violet tareme (drooping) eyes. Her standard attire includes a miniskirt, pleated skirt, thigh-high stockings, Mary Jane shoes, puffy sleeves, and a string ribbon tie.

Programmed for domestic service, Ilfa exhibits an obedient personality focused on household tasks, including cooking. Within narrative contexts, she serves strictly as a supporting character. Her role remains consistently positioned as a robotic maid fulfilling duties, with no documented background story, character evolution, or expanded narrative arcs across any official media seasons, films, OVAs, or spin-offs.
