Empress

Empress (エンプレス Enpuresu) is a major character and boss in Lust Friend.

Appearance
Empress has long blonde hair, red eyes and large breasts. She has curly red horns and red wings. Unlike most succubi, who only have a single tail, Empress has three purple tails. She wears a dress with a cleavage-bearing black top and a skirt that is white with red trim. On her head, she wears a tiara of the same colour as her horns. She also wears elbow-length gloves, stockings and high-heeled shoes, all black.

History

Background
Due to her ability to travel through time, Empress learned that the succubus world would eventually be destroyed. She therefore devised a plan to stop this by absorbing the human world into the succubus world, which would make all the men food for succubi and transform the women into succubi. As part of this plan, she constructed Fess Tower and took control of Fess's body.

Lust Friend
Through Fess, Empress summons Magrut into the succubus world, as she needs his body for her plan. She tells Magrut that she will send him back after he gathers materials for her to build Fess Tower (in truth, the materials are to give her the power necessary to enact her plan).

After Magrut gathers the materials and defeats Empress' subordinate Shandilla, Empress reveals herself. She explains her plan to Magrut and then takes his body, forcibly closing the game.

When the player attempts to reload their save, this results in what appears to be a new game with the Empress-controlled Fess summoning Magrut again. However, Empress soon realises that Magrut remembers the previous events. She then shows him a ruined Fess Town as an example of the eventual destruction of the succubus world. She leaves, releasing her control over Fess.

Magrut eventually returns to challenge Empress again. There are two diverging paths, depending on whether he chooses to defeat her or befriend her.

If Empress is fought and defeated, Fess tells her that she doesn't have to do this alone and that they can work together to stop the future destruction. Suddenly, they sense the same kind of magic as in the bad future. Fess decides to send Magrut back to his world. In this path, the succubus world is destroyed.

If Empress is befriended, the events play out similarly to if she's fought, with Fess attempting to send Magrut back to his world. However, Magrut is instead taken away by Mea and manages to befriend her, then is returned. This leads to the succubus world being saved.
