ALT Digital anime-style illustration of Hayase Nagatoro depicted as a demon character. She has tanned skin, dark hair tied in a high ponytail, and large dark horns. Smiling mischievously with sharp teeth, Nagatoro wears a light blue bodysuit, denim shorts, and a black choker while holding a dark strap or a leash. The background features vibrant purple and pink tones with stylized flame patterns, and a speech bubble reads: 'NOW YOU BELONG TO ME~' with a heart.
