Devils

Devils (悪魔 Akuma; sometime erroneously translated as "succubus"/"succubi") are a race in 62studio's games. They are similar to succubi but are less common and much more powerful.

Description
Similar to succubi, devils resemble human women with large breasts, horns, bat-like wings and spaded tails. They also share many of the abilities of succubi, such as draining human life force through sex.

The main difference between devils and succubi is that the former are far more powerful. They are typically the main villains and final bosses of games or (in Demon's case) a secret villain who cannot be defeated. Some specific abilities they have are:
 * Creating worlds: Lust Reaper created the world of Lust Grimm, and Demon created the world of Succubus in Wonderland. If the player goes through the genocide route of a game, Demon can create a copy of the game world for the player to continue playing in.
 * Destroying worlds: Lust Nightmare repeatedly destroyed the world of Lust Friend, and will do it again if the player cannot stop her.
 * Summoning people from other worlds: Demonia summons four people from other worlds to act as assassins to defeat Magrut.
 * Rewinding time: Lust Nightmare rewound time each time she destroyed the succubus world, which was how she could so so repeatedly. Although Empress (a succubus) also has this ability, it exhausts her to use it, while Lust Nightmare seems to lack the same disadvantage. Lust Nightmare is also able to use her power to revert Magrut into a child.
 * Interfering with the game itself: Demon can forcibly close the game window and interfere with save files.
 * Making contracts with humans: Demon made contracts with Lorina and Alice, giving the former immortality and great power, and the latter the chance to be in the same world as her sister. However, this can have consequences for the human if they sell their soul. Lorina lost her memories (including her original name) and her original body after making this deal. She gained a new body made up of magical power, but upon defeat her power began leaking out, almost killing her (surviving only due to gaining another new body).

However, devils do have limits on their power. For one thing, they can sometimes be defeated by humans, as happens to Lust Reaper and Demonia. They can also be sealed, as happens to Demon.

List of devils

 * Lust Reaper
 * Demon
 * Lust Nightmare
 * Demonia

Although Mel is described as a succubus, Demonia refers to her as "something close to a devil". Demonia also decides against fighting her, a testament to her power.

62-chan is described as a devil in her profile in GESTALTER. This profile states she can create succubus worlds and succubi, gives her the real name of "Valacgor" and claims her personality was very different before coming to the human world. The ending comment by 62-chan claims that this information is just a joke. On the other hand, the Q & A page in GESTALTER states that 62-chan created all of the games' worlds, though that of Succubus Puttel was changed greatly from her original plans thanks to a certain devil.

Background
In the past, Demon was a powerful devil who killed many other succubi and was a threat to the entire succubus world of Lust Friend. After many years of struggling, she was defeated thanks to the combined efforts of Empress (the succubus queen) and her friends. However, they were only able to seal her into a weakened form, that of a fairy.

Lust Nightmare was a devil born from Mea's desire for friends. One day, the girls around Mea proposed that she jump off a cliff to prove herself worthy of being their friend. Mea did so and was mortally wounded. Mea thought to herself that she should just give up and no longer have to suffer. However, Lust Nightmare called out to her. She introduced herself and asked Mea what she wanted. Mea replied that she wanted friends who would stay with her. Lust Nightmare revived Mea and brought her to the succubus world.

However, Mea still couldn't make any friends here as the succubi ignored her (seemingly because they could not perceive her at all). She became jealous of the succubi, who captured men and lived so happily with their friends. Mea's loneliness led Lust Nightmare to repeatedly destroy the succubus world and then turn back time, despite knowing that this would not actually heal Mea's heart.

Lust Grimm
The devil Lust Reaper admired the stories of humans and wanted to write her own. She therefore contacted the Brothers Grimm (hiding her true identity) with the intent of writing a story that would surpass theirs. However, she was obsessed with bad endings and her story was not recognised like those of the Grimms'. She wanted to express the beauty of bad endings to the world and therefore decided to rewrite one of the Grimms' stories. Her rewrite turned the story into another world for succubi, and she populated this by taking humans from their world and transforming the women into succubi. The characters within the book were also affected, with Rotkappchen, the story's heroine, also becoming a succubus.

Rotkappchen proceeded to draw the human Magrut into the world. However, Magrut proceeded to defeat Rotkappchen twice, forcing Lust Reaper to intervene. Magrut managed to defeat Lust Reaper as well with Rotkappchen's help, returning the story to its original state and freeing all the humans.

Lust Friend
When Magrut is brought into a different succubus world, Lust Nightmare speaks to him (though her identity is not revealed at this stage). She tells him that it's impossible for humans and succubi to coexist, and this is world where he can only kill or be killed himself.

Lust Nightmare appears in person if, and only if, Magrut succeeds in befriending Empress. If this happens, Mea brings Magrut into a dark space and then transforms into Lust Nightmare. She explains her nature to him and states that she will now destroy the succubus world permanently. Finally, she mocks Magrut for his efforts to befriend succubi and declares her intention to keep him with her, until she and Mea disappear. In the resulting fight, Magrut talks to Lust Nightmare and eventually succeeds in befriending her. Lust Nightmare disappears, leaving only Mea behind. If Magrut loses, Lust Nightmare proceeds to rape him. She reverses his time to make him regress into a child, intending to raise him up to be a proper friend for Mea.

Lust Reaper appears in the Arena of Fess Tower, and only if the player has obtained the Normal End and beaten the previous three arena encounters. She can be fought as a boss and can remove Fess' blessing from Magrut. Befriending her is a prerequisite for the true ending.

Demon appears throughout the game in the form of the Record Keeper Fairy. She allows the player to save their progress. Her dialogue changes depending on the number of enemies the player has defeated. Eventually, the Record Keeper Fairy in Magrut's house will offer to give Magrut a special badge which allows him to permanently kill succubi, claiming that this will allow him to return home sooner. If Magrut proceeds to kill all of the other succubi in the world, Demon appears before him as a fairy (now named a "Save Fairy"), congratulates him for "clearing the game" and gives him the option of saving. Demon then reveals her true identity and explains that Magrut's actions have allowed her to break her seal. Additionally, she says that Magrut has fulfilled her goal of destroying the succubus world. She tells the player to close the game window, and can do this herself if the player tries to continue. If the player tries to reopen the game, they will be faced with Demon again, who offers to create a copy of the game world for them to continue playing in.

One diary in Raspberry Plateau: Underground gives information on three devils (erroneously referred to as "succubi" in the English translation, but the original Japanese is "悪魔''). It describes Demon's defeat and sealing, Lust Reaper's shift in focus after losing to a human (Magrut), and the mysterious Lust Nightmare.

Succubus Puttel
If Azreth kills all of the succubi in the world, he ends up in a blank white space with Demon. Demon asks if he's still not satisfied after killing everyone and breaking the world. She tells the player that these events will repeat even if they try reloading. She then rapes Azreth, suffocating him with her breasts, and forcibly closes the game. Attempting to reload the save causes Demon to return Azreth to the point before he was suffocated. She offers to create a copy of the game world for the player to continue playing in.

Succubus in Wonderland
In the backstory to this game, Demon made a contract with the human woman Lorina. She gave Lorina immortality and another world to live in. Later, Lorina's younger sister Alice also met Demon (who she knew only as "a beautiful white woman"). Demon comforted her, told her stories involving difficult words and gave her a magical Joker card. Alice said that jokers weren't cute, so Demon gave her a King of Diamonds card instead, sending her to the succubus-filled world of Wonderland.

Demon appears in a few places throughout the game world as a generic succubus NPC. Talking to her in a secret part of Mel Forest is one step in the genocide route.

If the player discards the game's card key items into a void in Proof Undersea Tunnel and then starts a new game with "アリス" (Alice) as their name, the world will be distorted and the player can eventually find Demon. She congratulates the player and then causes a fake ending screen, after which the screen turns black. Moving around will bring the player to a white room with Demon, now in her real appearance. She says that the cards were what allowed the existence of the succubi, she wrote this story with these cards as a medium, and that throwing the cards in the the voids in the world caused its destruction. She thanks the player for doing this, then adds that the history and relationships of the succubi in this world were due to her own modifications, and that everything in this world was created for the player to destroy. She offers to reward the player, giving a choice to surrender to her or quit the game. The former causes Demon to shrink Reto and rape him by pressing her against her breast.

Carroll in Wonderland
While calling in assassins from other worlds, Demonia accidentally sent one of them, Lilith, to Wonderland instead of the intended destination. She interrupts Lilith when she is about to attack Reto and sends her to her correct destination.

LustGrimm Again
As in Lust Grimm, Lust Reaper rewrote one of the Brothers Grimms' stories, filling it with succubi.

Demonia creates various gaping holes in the world using her axe. She appears before Magrut repeatedly, sometimes assisting him in obtaining some of the pages he seeks.

When Magrut finally returns to his world, Demonia congratulates him and reveals that Rotkappchen has not truly been defeated. He thus has no choice but to return and Demonia will guide him to her if he fulfills one condition. Demonia leaves and Magrut touches a book to return to the succubus-filled world.

Demonia tries to subdue Magrut using the four assassins she'd summoned. When they fail, she tries to defeat him herself, but she loses. Having lost completely, Demonia gives up, tells Magrut to forget her if he wants a peaceful life, tells him that he must defeat the true mastermind Lust Reaper, and leaves.

A series of books in a strange space under the Succubus School reveals Demonia's link to another devil (possibly Demon). This devil was sealed by a human man, succubus princess sisters and an observer named "Valac". She plots to take Lust Reaper's world and her power. As she cannot act directly without strengthening her seal, she plans to use Demonia as an intermediary to manipulate Magrut. She gave Demonia her axe to create the holes, which lead to different spaces and will allow her to drain the power from Lust Reaper's world.
