A collar worn around a character's neck is a visual shorthand commonly coded toward submission, ownership, or pet-play dynamics within BDSM-flavored scenes, and the accessory gets its own dedicated tag for that reason. It frequently shows up alongside bondage or femdom tags to signal a broader power-exchange storyline, though it can also appear as a purely fashion-driven detail. Fans of the look and its symbolism can browse collar hentai manga and doujinshi on Top Hentai.
