Piltia is a halfling succu-girl employed at The Genderswap Inn. She mirrors Kanchal in stature, presenting as short with vivid blue hair styled in long locks featuring a distinct top curl and long bangs. Her purple eyes and fluffy ears create a youthful illusion contrasting her true age, noted as significantly older than Stunk. She wears a dark purple dress reaching mid-thigh, equipped with front pockets, complemented by a collar attached to thin white shoulder pads reminiscent of kitchen curtains. Additional attire includes a spirit-shaped necklace with a blue gem, baggy brown gloves, and dark brown boots. Her overall appearance utilizes a childlike aesthetic to attract a lolicon-oriented clientele.

Her personality sharply contrasts between a cutesy exterior and a dominant, assertive approach during intimate encounters. She articulates this duality with declarations like "Pain and pleasure are two sides of the same coin," demonstrated through actions such as taunting clients unable to endure her intensity. This dominance manifests in her preference for BDSM dynamics, wielding a worryingly large vibrating dildo and proposing activities like bondage.

Her professional debut occurs when Kanchal, transformed into a female halfling at the Inn, selects her to avoid adventurous interspecies encounters. During their session, she openly mocks Kanchal's limitations in handling her methods. While Kanchal's review scores the establishment a 4 for the gender-swap experience rather than rating Piltia individually, the interaction underscores her role in facilitating such experiences. Later, she appears alongside Lymee attempting to recruit reviewers for Genderswap, though they decline due to exhaustion. In a subsequent succubus film production, she temporarily adopts an innocent/submissive role opposite Elza the hyena-girl, showcasing professional versatility. Her narrative presence remains confined to her role as a succu-girl within the brothel setting.
