Succubus House

Succubus House (サキュバスハウス Sakyubasu hausu) is a recurring location in the games where the player can revisit past encounters and events.

Description
The general layout of the Succubus House is a small reception area followed by a large open space. The reception area has NPCs who explain the purpose of the house and perform other functions (depending on the game). Enemies appear in the open space once the player has fulfilled certain conditions: The player can talk to an enemy to fight them again, view their H-scenes or H-scene CGs, or view other information about them. Additionally, whenever the player completes an event, a corresponding NPC will appear in the open space that allows the player to view the event again.
 * In Lust Grimm, the condition is to obtain specific items. Each enemy has their own item, e.g. the Succubus' is the Succubus Heart.
 * In Lust Friend, the condition is to befriend an enemy.
 * In Lust Memory, the house is simply a single room and becomes available when the player clears the game.
 * In Succubus Puttel, there are two conditions. The player can either lose to an enemy to unlock them, or defeat the boss of an area to unlock all of that area's enemies.
 * In Succubus in Wonderland, the player can either defeat an enemy or lose to them.

Finally, the Succubus House offers an option to unlock all features, including ones that are otherwise inaccessible such as an infinite source of items. This effectively allows the player to view most of the game's content in one location. However, activating this option prevents the player from ever leaving the Succubus House. Consequently, it is recommended that the player save to a new save file after doing so.

Enemies
All or almost all enemies in a game can be found in that game's Succubus House. An exception is Dark Fess, who never appears in the Succubus House as she is exclusive to the genocide route of Lust Friend.

Notable Treasures
Starting from Lust Friend, there is a silver chest in the Succubus House that contains extremely powerful equipment, allowing the player to easily progress through the game without any grinding. In Succubus in Wonderland, this chest is instead found outside the house itself.

Services
The Succubus House contains all available services (for the current game), such as the Addiction curing NPC and the Memory erasing NPC. It also contains services not available anywhere else, such as: an infinite source of every item in the game; a source of every skill in the game; and a way to change the player's level freely.
