Dalvie

Dalvie is one of the residents of Transylvania, and the owner of Lil Shop o'Horrors.

Meeting Dalvie
Lil Shop o'Horrors becomes accessible after finishing Manor quest, alongside other shops and houses in Transylvania.

Special wares
Marin is still angry at you. When you try (and fail) to establish a contact, she would demand you serving her, thus starting the First Marin's challenge mini-quest.

Once you finish it, you can purchase the Living Underwear from Marin, with price depending on how satisfied she was. Default price is $1000, with her increasing it to $1200 if you anger her in any way, and reducing it to $800 if she was satisfied (which requires finishing the quest in optimal way).

Body shop
After obtaining all necessary items, you can talk to Dalvie and inquire about the locked door. Regardless of your answer to their question, they would unlock their own Body Shop to use. Here, you can change your body, with most options being more or less "animalistic" (like animal ears, or tails). Using it costs $500 upfront for every use.

Trivia

 * Dalvie changes their appearance every time the player visits them.
 * If the trap shrine is disabled, they always appear female.
