Guide Book Entry
Fallen maidens who lead humanity to monsters
- Dark Brave - Overview
A "hero" is a person who has been blessed by the Chief God to fight monsters. In the "kingdom of Lescatie", which nurtured many heroes, "Wilmarina Noscrim", the strongest among the heroes, the symbol of that country, was the hope of humanity. In turn, the "dark brave" is a hero that was the hope of humanity and became a mamono, she is a symbol of the fallen Lescatie and the transformation into monster girls.
Dark braves lead the dark knights and lead the people of Lescatie wherever they are needed. They are blessed by Lady Druella and have her favor. In the mamono realm of Lescatie, the dark braves give themselves over to their own desires and spend their days filling them with pleasure. However, such dark braves are perfectly suited to fallen Lescatie. The dark braves, who are the most beautiful and obscene mamono in Lescatie, are genuinely admired and respected by the people of Lescatie who crave further depravity.
As symbols of the "Mamono Realm Lescatie," the dark braves, seeing the disruption of the pleasure and happiness that fills Lescatie, eventually become convinced that only by leading all of humanity into an utopian world of pleasure can they bring depraved wellbeing to the hearts of Lescatians.
- Dark Brave in Battle
Though the dark braves have individual differences, many of them possess the uncountable strength of thousands of warriors. Their power is beyond the norm that a single man could wield; enemy soldiers of the Order sometimes compare them to a natural disaster. The presence of even a single dark brave on the battlefield greatly affects the outcome of the battle. Alone, the dark brave is able to monsterize many people with his sword and create a mamono realm on the battlefield with his magic, instead of incinerating the entire area. In addition, ironically, people who have the talent to become "heroes" simultaneously possess high qualities as "monsters." dark braves, who also have excellent succubus talents, have a sensual charm that inevitably brings sex to mind. Their mere presence creates an obscene atmosphere, leading people to fall to their hidden desires. At the moment of the Hero's fall, the power given by the Chief God to subdue monsters becomes the power of the dark brave and is now used to turn people into mamono. And thanks to the power of mamono, every time the dark brave makes love to her husband and enjoys pulling his essence, her power continues to grow.
Originally, heroes is not a name for a class of warriors, the word refers to those who have received power from a deity. For this reason, a hero can usually be called a "warrior" as well as a "mage". Therefore, the dark brave depicted in this book has the skills of a "dark knight."
- Social Status and Origin
It is said that Lescatie, which was one of the leading countries in the world that "produced heroes," had the most heroes. Heroes held a high position in the country, but possessed only symbolic power, with no political power. At the helm were powerful priests and nobles who ostensibly supported the heroes, being in reality gray cardinals who controlled them. At the decline of the kingdom of Lescatie, their factions managed to make a mere facade out of the royal family, and from the knights of the kingdom to assemble their private armies. For these people, the number of heroes among their knights was one of the most important factors that determined a person's social status, so they worked hard to attract heroes to their armies. As much as the common people extolled Heroes, in essence they were not even mere soldiers, but resources for a political struggle whose own influence was suppressed.
On the other hand, in today's Lescatie, which has become a mamono realm, the dark braves are in a position where they can "follow the call of the heart." Some seriously act as heroes, but in many cases they usually spend each of their days having intercourse with their spouses; other heroes try to right their wrongs to make their hometowns happier and more pleasant. For example, there are such heroes that freely use their power and position to open schools to raise children. Although many of the dark braves are part of the military, they will only participate in expeditionary missions when requested to do so. And it is worth bearing in mind that if they do not like it, they may refuse even the request of the esteemed Lady Druella. Of course, only a husband in bed can control such capricious and unrestrained heroes. While not every one of them has the power, it can definitely be argued that the influence of the dark braves is now greater than it was in the old Lescatie. "The Seven Princesses of Lescatie" are second only to Druella as ruler of Lescatia.
Although the symbol of Lescatie has remained the same, those who should be that symbol have changed greatly. They demonstrate that the heroes of Lescatie, who were the hope of mankind, have fallen and sunk into corruption. The dark braves are now respected as beings who corrupt people everywhere. Hero is just a title, now they spend their days indulging in pleasures with their lovers rather than dealing with people or the country. Because their heroes have fallen to such an existence, the people of Lescatie can realize that their own country has fallen, and they can live their lives immersed in pleasure and worrying about nothing. Moreover, it is the dark braves who are the ones who are more absorbed in pleasure with their beloved than anyone else in Lescatie, their bodies literally drowning in essence. The scent of a beloved spouse is always around them, which is an example for many other mamonos to follow. Watching the dark braves, other monsters look forward to becoming similarly obscene creatures.
Great Magic Sword (★★★)
The great magic sword is a common mamono realm weapon that emits a tremendous amount of magic. If it is a sword, one swing of it will generate a wave of magic that will strike anyone in its path; if it is an axe, its blow will shake the ground and stun everyone around it, and the arrow fired will turn in flight into a huge, rotating whirlwind and will strike the enemy with a piercing storm. The dark heroes, who possess the power of many people, even with a "normal movement of the weapon" are able to generate a "great magic sword" of enormous power, which is only a manifestation of their "immense magical power". Although the "great Magic sword" is equivalent to a natural disaster, it contains the obscene magical power of the dark brave, therefore it does not take people's lives, but it turns many people into monsters.
A battle with the dark brave is not like a normal confrontation between a monster and a human, as it is almost impossible to defend against their attacks. So there's nothing wrong with just running away. Regardless of the size of the army that will be thrown against him, a swing of the "great magic sword" will scatter a rain of arrows or bullets and monsterize all humans before the dark brave.
Eternal Dwellers of the Mamono Realm (★★★)
This technique clothes the dark brave in a dense cover of mana to always keep her surroundings as in a mamono realm. This ability to clothe herself in the mamono realm, even if she is not in the mamono realm, allows the dark brave to activate their body and spirit as if the Hero were really there, allowing her to maintain maximum amplification at all times.
The mamono realm, which envelops the dark brave, is not only a powerful amplification, but also a powerful barrier that protects her. If medium-level spells are used against the dark brave, when faced with the Mamono Realm, they will lose their effect and be distorted in an obscene way and self-activate, filling the surrounding space with mamono mana. Even spells like the wall of fire will be meaningless, as they will simply corrupt those around the hero. Also, spells that take away mana and draw out energy will be ineffective on that monster that is always in the mamono realm, which retains an "obscene spirit" within it.
The mamono realm is a space that greatly enhances the reproductive instincts and abilities of those within it. It is because of the presence of the mamono realm around them that dark braves are always the ideal women and are in a state in which they can best demonstrate their succubus power to a man. Thus, they are still the best women to channel their husband's desires for sex and excite him. In other words, with this technique, the dark braves can easily induce their spouse to coitus at any time and be the best during sex. It is probably this element of this technique that is most important for most dark braves.
Depraved Devil's Dress (★★★)
This arcane technique can only be used by a limited number of dark braves wearing magical armor that unleashes the wearer's full potential.
The depraved devil's dress is a special armor that only the wearer can use. It is created from the essence of her partner and contains various curses to give the dark brave her maximum power. The Depraved Devil's Dress is a tight outfit worn so that it appears as if it is cutting into the crotch between the thighs. On the inside the Dress is filled with essence and slime, also on the edges inside it is covered with tentacles that invade the monster's body all the time. Since the garment contains the essence of her husband, the most powerful amplifier for a monster girl, it greatly increases the power of the mamono. The pleasure of this armor is close to that given to dark braves by their husband, but it never surpasses the pleasure given to them by their lover's hand. On the other hand, the curses of the Armor will continue to heighten the Heroine's arousal and her lust for her lover. Inexperienced dark braves, having greatly enhanced their physical parameters and magical power with the Depraved Devil's Dress, will be able to use this power only to have sex with their husband. Even the dark brave, who fought with only one Dress glove, which corresponded to her own strengths, nevertheless licked and sucked her fingers all night after the battle, penetrating deeply into her mouth. Her passionate lust was so strong that she was nearly driven mad by her lover's desire.
When the dark braves fights while fully clothed in the Depraved Devil's Dress, it allows her to think and act as if she continues to take pleasure from her husband, which is a normal everyday occurrence for them, as if she is still deeply absorbed in the pleasure that her lover gives her. In peacetime, this garment evokes such powerful sexual desire and lust that the heroine's body and mind go crazy. But, on the other hand, it also keeps her husband's sperm inside her lower abdomen and also delays the sensation of his hot flesh inside the monster. This allows her to continue to feel like she is having sex even when the couple is not together. Such an indecent existence is, of course, too extreme and is the prerogative of only a few inma.
At this point in Lescatie, only the Seven Princesses of Lescatie can wear the Depraved Devil's Dress at all times, and of course it is one of the abilities that made them who they are.
Druella's Blessing (★★★)
Along with the mission to turn all humans into monsters and spread the mamono realms, dark braves also receive a powerful blessing from Druella. Thanks to it, even if a monster from a race that is not normally capable of turning others into mamono has been blessed, the dark brave gains the ability to maneuver opponents into the same race she belongs to, or into succubi, with attacks or magic. In addition, the blessing given to the Seven Princesses is even more powerful. They were given the power, like the lilim, to turn human women into whatever monsters most suited the women's character, to make their downfall most perfect.
Hero's Charisma(★★★)
The hero's strongest charisma causes admiration and envy in those who look upon her. It was not acquired during their conversion to mamono, but was retained from the days when they were human heroes. It is not known whether it is because they are so attractive that they are beings chosen by the deity, or whether they were such people because they have advanced one step beyond the rest of humanity. Nevertheless, all heroes possess a special charisma. Fascinated by the hero's presence, people will experience "admiration" and "envy," for the hero's appearance is what humanity should look like.
And this charisma does not disappear even when the hero becomes a monster, but rather only intensifies as the mysterious allure of mamono is added to it. The author also had the opportunity to experience this when he first met Wilmarina. Seeing her made me realize that I wanted to be like her. The smooth, sensual, and arousing movements of her body testified to the pleasure and ecstasy into which she was immersed. So, too, Wilmarina's enchanting smile was certainly a sign of happiness, of which she was absolutely certain. The way her breasts were bouncing made one wonder how pleased her husband was to play with them and indecently touch them with his hot hard flesh. Watching her lecherous mouth and the tongue that peeked out as she talked, I unwittingly licked my own lips with my tongue. The moment I realized this and was able to restrain myself in front of that pretty face, I felt a strange taste and a sweet numbness in my frantically pounding heart. The feeling hasn't left since then.
But above all, I felt "envy" towards her, mixed with a desire to become like Wilmarina. I was firmly aware of these feelings in my heart and clearly recognized this desire in my thoughts. Even if she was a monster, as a hero, she remained a human being on a level above me. Being around her, one could only feel intense envy or intense admiration for her. That's why it was very easy for me to accept the invitation to the Fall from such a dark brave, since I myself felt the desire to become a charming monster like her.
