Runba Luseine III, a Komondor breed Hungarian sheepdog, resides as a pet in the Enjō household. He displays a recurring habit of licking Maihime Shirayuki, often targeting her private areas. Maihime denies enjoying these interactions, though they generate comedic scenarios. Thematically linked to Maihime, Runba reflects in her subconscious desires—her idealized dream features puppies encircling her—and in practical elements like the dog-inspired collar incorporated into her specialized combat suit during specific sequences.
