Pixie

Story
While exploring the Catacombs, Rinny gets captured by a magic mirror and vanishes without a trace, becoming another victim of the mysterious villain who's terrorising Transylvania. With no way to escape on their own, Lust Doll keeps wandering around, until they accidentally finds a secret entrance into a hidden tomb.

There, they encounters a pale sorceress preparing for some strange ritual. After resolving initial hostility, sorceress introduces herself as Pixie. She confirms that so-called "Master" is indeed behind the recent events, including Rinny's disappearance, and currently is their common enemy. The only way to deal with the Master is to infiltrate the Manor, using enhanced servant uniform for disguise and gather missing pieces after making it inside.

Lust Doll successfully discovers the secret entrance (by interrogating one of the maids) and the prison where all abductee are kept: all but Rinny, who's currently in torture room. Lust Doll goes there, hoping to free her and steal the keys, but finds only Rinny. When the two goes outside, Master finally makes their appearance; mysterious and creepy woman introduces herself as Edith, and uses her magic to dismember Lust Doll, without causing any pain or physical damage – in fact, the body parts are still alive and can be felt, even controlled to a degree. She then tries to recapture them, but Rinny manages to escape, carrying her friend's body.

Pixie offers her help once again, by causing a diversion in the dungeon, which distracts all servants and allows to look for missing limbs around the Manor. Once all body parts gets discovered, they all gathers in Master's bedroom to perform a ritual to reverse the magic, only for Edith to show up... and reveal that title of "Master" actually belongs to Pixie, not Edith, no matter what the others believe. She then puts Pixie out of combat by threatening to destroy a very important book if she intervenes, all while insisting that Pixie should conquer the world and rule as the "god", while Pixie wants nothing to do with it.

Edith then redirects her attention to uninvited guests, deciding to finally disposes of them. But, even naked, Lust Doll and Rinny manages to best Edith in battle, as she no longer has surprise factor on her side, and Pixie takes away her scythe and puts her in prison, while everyone else gets released.

Tactics
Pixie uses exclusively physical attacks, unleashing devastating magic on every second turn. Context menu provides option to grab her, but it invariably fails, and, after 4 fails, opens a choice between chasing her or backing off; choosing the former ends the battle in your defeat immediately, while the latter disables context menu for duration of combat.

There's nothing you can win or lose in this battle, as regardless of outcome, Pixie would realise that you aren't working for Edith and stopping attacking you, so no need to waste mana and consumables on it.

Scenes

 * In the Pixie's Lair, there's a hole with some eldritch creatures who would do lewd stuff to Lust Doll if they decides to "feed" them.
 * During initial encounter, this scene would be forced on the player if they fight Pixie and lose; the player has to choose between two options, one for character with vagina, and one for character with penis.
 * After being properly introduced to Pixie, this scene may be repeated at will, giving the following options:
 * Feed alone
 * Eldrich glory hole
 * Tentacle worms
 * Have Rinny do it too
 * If The dream quest is done and Manor quest is complete, the player may try to grab Pixie's hand; this scene has two versions, depending on whether Rinny is present or not.
 * When done by alone, Pixie summons grave hands, creeping Lust Doll out into abandoning the idea.
 * When done together, you would struggle for a bit, but ultimately Pixie would evade you.
