Promestein

Promestein is a powerful scientist with vast technology. In reality, she is an angel who devotedly follows Ilias’s cause without question, having created the chimeras at Ilias’s order. Despite being the Ninth Rank of the Hierarchy of Angels, Promestein is one of the leaders of Ilias’s army due to her vast knowledge of technology and command over the chimeras. She is also the leader of the Seekers of Truth.

Although she serves Ilias, Promestein secretly despises her as she is aware that Ilias did not actually create the world. This led to her being ridiculed by other angels.

Promestein’s personality is very calculative in nature, showing no emotion in any of her appearances and speaking very little, other than to observe others and introduce herself. She does show some levels of sadism however, as seen when she lays siege to the Monster Lord’s Castle at the end of Chapter 2.

Biography
Several hundred years ago, Promestein was a knowledgeable worker who was monitored by Hermes. However, Promestein had an insatiable curiosity of how the world works, but was constantly told that it was just Ilias's work, and as a result other angels made fun of her. After seeing how humanity struggled against living their lives by just blindly following Ilias, Promestein introduced fire to them, but by breaking the rule of coming into contact with humans, Promstein was condemned to prison for hundreds of years. During this time, she dissected small critters that wandered into her cell, created various alchemy tools, and studied complex formulas to grasp the truth. Black Alice eventually bargained for Promestein's release, creating an alliance between the 8th Monster Lord and the angel scientist.

In present day, Promestein first appeared as Luka drags Alice out of the Haunted Manor, bringing supplies to Chrome to help her in her research, but finds out that she has left. She recognizes Alice as the Monster Lord then quickly leaves.

When Luka returns to Lily’s mansion at the Witch Hunt Village, Promestein is there, suggesting that she helped or supplied equipment to Lily for her crude experiments. She sees Luka, but leaves shortly after. Luka asks Alice if Promestein is a monster, but she isn’t able to trace any sort of monster blood or power within her.

In Grangold, Alice hypnotizes a female magic engineer to reveal how they detained the Queen Ant. She reveals that years ago, the same strange scientist woman, identifying her as Promestein, came to them and “gave humans fire” (advanced technology), and has been supplying it to Grangold over the years, but recently stopped coming. Later, Luka asks if Promestein is human, but Alice doesn’t think so either.

Luka then encounters the scientist again at Remina. At first, he assumes she lives there, but then realizes she may be involved in the massacre.

After Luka revolts against Ilias, Promestein appears leading the attack on the Monster Lord’s Castle, revealing that the chimeras were all her handiwork. Luka yells that their defeat will never happen, until Granberia and Alma Elma receives smack-downs by Arc-En-Ciel and Hainuwele, respectively, as well as Amphisbaena, Tsukuyomi, and Rapunzel appearing on scene; the true masterpieces of the chimeras created and modified to exploit the weaknesses of the Four Heavenly Knights and the Monster Lord. Luka attempts to attack the mastermind, but Promestein dodges using Zylphe and explains that she had analyzed and is mass producing artificial Spirits. Alice reminds him that he’s not alone in this battle, and with angels and chimeras closing in from all sides, the angel who’s mass producing monsters, plus the one pulling the strings, they charge into the fray together.

After Luka manages to defeat Cupid, Valkyrie, and Archangel Ariel, Promestein calls out to Eden, the leader of the angelic forces, a failure. Alice then decides to attack Promestein; Arc-En-Ciel, excited, tries to step in, but Promestein stops her as there are already countermeasures against Alice and Luka. Alice punches, but Promestein, using the same barrier magic from Grangold, manages to seal Alice, much to Luka's horror. Promestein explains she had studied a seal called the Six Ancestor's Great Seal, used to seal Alice I (First) as well as the six ancestors of all monsters, and successfully reproduced it. Promestein then attempts to use her countermeasures on Luka; the power of the Four Spirits have completely faded. She then explains that she managed to develop another seal that blocks out the nature of elements over the entire world. A Chimeric Beast attacks just to prove her point, effortlessly avoiding his dwindled Lightning Sword Flash and even driving through his parry. Promestein then offers Luka a choice of surrender or refusal.

If Luka surrenders, he is taken to the Drain Lab, where Radio rapes him with various machinery all over his body. This rape scene is added to Promestein's first Monsterpedia entry as "Rape Scene 2" and is thus required to complete the Monsterpedia.

Refusing, Amphisbanea is ordered to sever Luka's limbs, but a large vibration interrupts her; its Tamamo with the unsealed Giganto Weapon. It manages to annihilate most of the chimeric forces, but is easily defeated by Arc-En-Ciel. Promestein is surprised at the beast's resurrection, commenting that she didn't expect anyone else to have the knowledge of chimeras. She then explains to Arc-En-Ciel about how powerful the Giganto Weapon is if at full power, and then tells Luka that nothing can stop her five top chimera, dubbed Next Dolls. orders the Castle mopped up, but Tamamo steps in, noting that the chimera forces are mostly comprised of beast creatures. Her aura alone is enough to terrify the Chimeric Beasts; Promestein orders a withdraw as they already have accomplished in weakening the two most threatening monster forces, much to the dismay of the Next Dolls. Luka chases after Promestein, ignoring Tamamo's warning.

Luka suspects Promestein is hiding out at Remina and heads there, where a strange girl (Black Alice) leads him into Promestein's secret laboratory. Promestein is a bit surprised, along with a young Alice appearing, revealing to have partially broken the seal using magic she had learned from Tamamo. Promestein, acknowledging the weak forms of her foes, transforms into a seaweed-like monster, boasting that it once belonged to an ancient creature, and then attacks. Alice manages to hit Promestein, stating that her experimentation resulted her degrading from an angel to a monster, but Promestein continues boasting. During the battle, Luka and Alice aren't doing so well until Luka suddenly enters Serene Mind despite Undine being sealed. Promestein resorts to using Zylphe, but Luka is still capable of reading her flow, which Promestein calls nonsense.

After being driven back, Promestein attempts to inject herself with a syringe, but Black Alice appears and stops her, stating that it is too early to use that "White Rabbit" injection and teleports her away.

Promestein then awakens in the Drain Lab, having returned to normal and recovered from her battle injuries. There, she meets the members of her Seekers of Truth: La Croix, Laplace, and Lucia. Promestein reports that even though the Monster Lord and Fake Hero have been weakened, they are still not completely powerless, and that Black Alice is aware of the "White Rabbit". She then notes that herself and her subordinates are all from different races; Angel, Monster, Machine, and Human, respectively; and they all share one thing in common: they are seekers of truth, overcoming any obstacle in their way including a god while recruiting other truth-seekers. Promestein then orders La Croix to not let anyone near a device and Laplace to gather energy for what is to come, and Lucia then leaves for her hometown Witch Hunt Village as a "messenger of slaughter and destruction". Laplace cannot fathom why Lucia cares about a village in the middle of nowhere, but Promestein responds that she is going to destroy it; Laplace thinks human thoughts are too irrational, which is something to Promestein's liking. All four then part ways, but the very same Cupid that aided in the assault with the Monster Lord's Castle arrives momentarily and discovers the Drain Lab then goes to report to Eden.

Sometime later, Ilias questions Black Alice about what she did with the "White Rabbit". Ilias comments that the plan may go astray if it breaks Promestein's body, and then states that no matter what one drinks, they will not become the same as a god, and even so it isn't as pleasant as one thinks.

After Luka reclaims Gnome, Promestein calls Eden a failure once again. Eden rants that it's her chimeras that are doing bad, and Promestein retorts it was unexpected and she needs to delve more on her research. Eden then tells her that she can read her plotting from behind the scenes and that she does not trust the scientist, but Promestein (sarcastically) says she's a heartfelt supporter of Ilias.

Later on, when Luka reclaims Salamander, Tsukuyomi and Amphisbaena apologize to Promestein for not being able to perform their duties. Promestein is impressed how Queen Alraune's Aztec Rose managed to sufficiently weaken Tsukuyomi, and dismisses Amphisbaena's failure on killing Erubetie as Throne Eggiel was unable to stall Luka long enough for the chimera to finish the job, and again calls on the failure of Eden. Laplace then asks about Lucia, and Promestein suspects she has failed and defected, and says Laplace couldn't possibly understand it due to her AI logic. She then discusses that "White Rabbit" is advancing, and must be aware of Black Alice's actions since she knows about it, although they can ignore the useless Seraph. After Promstein calls dismissal, Cupid reveals to have overheard the conversation and leaves to report to Eden.

Once Luka recovers Undine and thus has reclaimed all four spirits, Black Alice and Promestein call Eden names for her massive failure of invading the world, and that Ilias will be very angry. Eden rants that they have failed too, but the two say that it's still her fault for not commanding correctly. Promestein leaves afterwards, sarcastically saying she doesn't want to trouble the "great Seraph" much.

In the Drain Lab, Laplace wonders about the meaning of her existence and asks La Croix about it. The machine asks why Promestein gave her human thought patterns. La Croix mentions that Promestein has a deep passion for humans. In the ancient times, it is said that she rebelled against Ilias to give knowledge to humans, and was confined as a grave criminal.

Promestein
''“An angel who studies biology and technology that serves Ilias. Though she is an angel of the ninth circle, she was given a special mission by Ilias. Her original body was that of a normal angel, but she has since transplanted an ancient seaweed that she spend generations researching. She seems to have fairly high prowess for combat.''

''The original reason she had for going against the Goddess’s will and studying science is not known. It is only known that she was imprisoned as a criminal angel before Ilias gave her an important mission. A very strange existence among the angels, her fellow angels refer to her as a Heretic sometimes.”''

Promestein (Final Form)
"An angel who dedicated her life to the pursuit of knowledge. She imbued her own body with the genes of an ancient form of monster seaweed, in order to become closer to Dark God Alipheese's power. But, unable to control that power, her body explosively expanded. Even this runaway power was predicted by Promestein, though. After assimilating with pure holy energy, she was expecting to be able to stop the runaway power and maintain control.

''Taking advantage of the re-creation of the world, she intended to betray Ilias. Her true aim with Chimeric research was to create an army able to defeat the armies of the Heavens. Her Next Bolls, ostensibly created to counter the Heavenly Knights, were also supposed to be used to defeat high ranking angels. In the end, all of her creations were destroyed, and she fell at the hands of Luka himself."''

First Battle
A very difficult fight, hence she is being one of Ilias' right-hands. She can dish out a lot of damage, making Meditation a necessity. Alice will help to some extent, but she is not as powerful as she was before.

Just before Luka takes a fatal blow, he will enter Serene Mind, granting high (~80%) avoidance and costing now 2 SP instead of 4. However, Temperance, which occurs right after Wind Spirit Summon, will still hit him, so Guard is necessary. The rest is straightforward, attack normally and use Meditate and refresh Serene Mind as needed.

If Luka succumbs, Promestein's left arm, a large flower-like organ, attaches itself to Luka's penis and sucks him dry. The rest of Promestein's plant-like body then surrounds itself on Luka and devours him entirely, resulting in a vore ending.

Second Battle
Although this is Promestein's final form, this battle is actually not too difficult, as all she has are high damage attacks, wind and earth spirits, and a bind that leads to a one-hit KO. Keeping the Four Spirits up will easily counter all these, and go on the offensive and she should go down quickly.

If Luka loses, he is pulled into Promestein's large plant predatory organ where he is eaten.

Promestein
"Research like that is complete heresy. There’s some use for it but… …Excuse me, you don’t need to hear about that. I, the pure Ilias, shall guide you. During this fight, you should regain your serene state of mind. Once you do, make sure to never lose it. With that, you’ll be able to avoid most attacks… But if they hit, they are painful, so always keep an eye on your health. In addition, after she summons the wind spirit, she will use a powerful attack. Make sure to guard if you wish to survive it. Since your opponent has a large amount of health, expect a long fight. Keep an eye on your SP, and make sure you always have enough to recover and keep your serene state. Now go, oh brave Luka. Don’t hesitate to beat that great sinner to a pulp."

Promestein (Final Form)
"Promestein... Just how far did your horrible research go? You've become a true demon, at last. Divine punishment awaits. Close in form to a monster now, a serene state is effective. Fallen angel dance isn't too effective, so Sylph need not be called. Her restraints are also powerful, so Gnome is required. The damage reduction will help a lot, too. As before, make sure to summon the opposite attribute if she summons a spirit. Her HP is very high, so prepare for a long fight. Now go, oh brave Luka. Make her taste the thousands of years of my anger..."

Trivia

 * Her name is a portmanteau of Prometheus and Frankenstein. This references her tendency in-story to “gift” humans with arcane knowledge, in the same way Prometheus gifted humans with fire, along with her and Frankenstein both being “mad scientists” who try to create life. All three characters also defied gods, although Promestein allies with Ilias as a means of achieving her goals.
 * This can also reference Marie Shelley’s full title for the original Frankenstein: “Frankenstein; or The Modern Prometheus”.
 * She mentions that she originally gave humanity fire, like the mythical Prometheus did, suggesting that at some point in the past she may have been more supportive of humanity than she seems to be now.
 * In the third chapter she reveals that, despite using them in her experiments, Promestein loves humans more than any angel other than Micaela and Lucifina, for their curiousity and drive for discovery, going as far as naming humanity her successor in the striving for knowledge.
 * Her angel wings and halo seem to be translucent, as opposed to the other angels. What this means for her or her character is yet to be known; it could hint at her ability to disguise as a human, though it is still uncertain whether this is exclusive to her.
 * Promestein has performed the most evil actions directly in the game, from Chrome and Lily’s experiments over the Chimera Dryad in the Forest of Spirits and the Grangold incident to the siege on the Monster Lord’s Castle and finally the Slaughter of Remina.
 * Promestein is the only Seeker of Truth whose name does not start with a "L".
 * The background music when she sealed Alice at the beginning of Chapter 3 is J. S. Bach's Ruht wohl, ihr heiligen Gebeine from St. John Passion.
