Hiding equal lecherous power in their swords, they fight alongside the knights
- Dark Esquire - Overview
The "dark esquires" are those who have taken up arms to fight alongside their spouses, the dark knights and the dark braves. Having a dark esquire fighting alongside a dark knight becomes a major strength of that knight and enhances her so much that it is as if she becomes a hero. The "dark esquire" of Lescatie is not a knight's servant, but a full-fledged "knight" who has officially received the title from Druella and the Seven Princesses of Lescatie. But while a dark knight is one who in battle defends his country, his people, and his spouse, a dark esquire is a knight who in battle defends his soulmate. This position in no way tarnishes a knight's honor, at least in Lescatie. The story of the knight helping the princess he loves and the story of the esquire helping his knight lover are equally popular there. The latter are even considered preferable.
The dark knight warrior classes I introduced earlier in this book are mostly recruited from monster girls, but there are more human men than monsters among the dark esquires. The main feature is that this is a class of warriors, which includes a large proportion of the men who became incubi through sex with the dark knights.
- Dark Esquire in Battle
On the battlefield, the esquires are in line beside their wives, the dark knights, fighting with whatever they know how to use - a spear or a sword. Of course, the strength of the pair of the dark knight and the esquire is generally inferior to the strength of the dark knight squad, but fighting together with the dark knight, the esquire not only increases the strength of the knight, but also his power grows, so together they will be much stronger. Fighting hand in hand, such a pair will be much stronger than separated or than two other dark knights.
The secret of this power lies in the "essence" of humans and the "mamono mana" of monsters. Mixing the "mana" of humans and monsters causes the mamono mana to increase both quantitatively and qualitatively. This usually happens when they exchange energy during copulation, when a man pours his mana into a monster maiden or a mamono squeezes it out of a man. In other words, the more the dark knight and the dark esquire have sex, the more they can increase their powers. To some extent, this exchange of energy between the pair will take place even in everyday life if they are just around each other, not just during intercourse. It is important for dark esquires to make this normal cycle of mana exchange even more active. As they say, if an esquire is a talented man, he will be able to establish the same energy exchange as he does during sex. The secret is to eliminate the difference between the time taken up in ordinary activities and the time spent on intercourse. Your body must recognize that even that time is "just moments in the middle of coitus with your wife." While not having sex, stay as close to each other as possible, and it is also advisable to keep close contact with each other, for example, by intertwining your fingers, even while you sleep. In addition, it is also important to make your body aware that you are still in the process of coitus, even in everyday life, regularly caress each other and perform acts of love such as kissing. When a man is practicing with a sword, his body usually thinks the intercourse is over, so step back with your partner into the shade during the practice. It will be enough for her to lick and suck her spouse's aroused cock in her mouth to maintain the effect. Spiritually, it is important for the esquire to maintain a mental state when he is overcome with sexual lust for his Knight, when he craves his spouse's body and pleasure from her to the maximum. If the dark esquire can achieve such a state, the dark knight, who is his partner, will be in the same state as he is. Thus, they will be able to maintain a state in which they actively exchange energy with each other. In either case, it is important that your bodies and hearts be fully interdependent.
You could say the way of life that a dark esquire needs to lead is to drown completely in days devoted to coitus. It seems simple enough, since mamonos are originally creatures that captivate men with their bodies and pleasure, to the point of complete dependence. However, the real difficulty for aspiring dark esquires is that, while leading a completely depraved life and drowning in pleasure, they continue to enter the battlefield again and again. Even the training of a dark esquire tends to become difficult, as during this time the pair can easily escape, lock themselves in a bedroom, and even leave the ranks of the Knights for good. Only people with enough fortitude to fight for their knight spouse and hold the sword despite the debauchery going on can become strong dark esquires. Such people can continue to maintain a balance between the ways of the sword and pleasure, and like incubi are able to develop their physical and sexual abilities beyond human limits. The strength of such dark esquires can be comparable to or even surpass that of monsters.
- Social Status and Origin
Originally the title of "esquire" was given to those men who were servants and apprentices of knights. When Lescatie was still a holy kingdom, "esquires" chose one knight as their lord and after several years of service, such as tending to weapons, taking care of horses and armor, they were officially knighted. When Lescatie became a mamono realm and the meaning of "Knight" changed significantly, so did the meaning of "esquire." The dark knight must have her spouse beside her, not her subordinate, so the statuses of dark knight and dark esquire are equal. The Esquire does not have to be subordinate to the Knight, as they are not "knight" and "servant," and, on the contrary, the Esquire can retain the dominant position.
For the most part, dark esquires are volunteers who have offered to support their spouses who are dark knights. That said, some single men also aspire to become esquires. However, since dark esquires are part of the army of dark knights, by admitting that he is looking for a life partner, such a man will instantly find himself in the spotlight of unmarried knights, many of whom will want to get to know him better. In addition, if the dark knight asks a man to become her esquire or, on the contrary, the esquire offers the knight to fight together, it is tantamount to a marriage proposal.
Dark knights fighting together with dark esquires cause a lot of envy of other Knights, because they have a husband who fights together with them and protects them. But the most important reason for envy is that the dark knights and Esquires share their love with each other and look very happy. For this reason, many unmarried dark knights are looking for esquires, and nowadays many of them keep offering some single male warriors and captured enemy soldiers to become their esquires. And at the same time, there are those among them who will not let their spouses go to the battlefield because it is dangerous. They simultaneously want to be with their lovers at all times, but at the same time do not want to put him in danger. This seems to be a serious dilemma for many dark knights, even those who already have an esquire.
Although I wrote earlier that the dark esquires are mostly men, there are nevertheless plenty of monster girls among them as well. In fact, there are also dark knights and dark braves who are men in Lescatie, just not as many. Many of the monsters who became dark esquires participated in the Lescatie invasion operation under Druella and fell in love with the Knights who fought them. And because their husbands wished to remain knights, these mamono chose the dark esquire path to support their lovers.
Monster Couple's Breath (★★☆)
By constantly exchanging mana with each other, the dark knight and the esquire can synchronize their feelings and even share their thoughts. Without saying anything, they can understand each other's thoughts and know exactly what their partner will do. This technique eliminates the need to talk during the battle and even a wink will become unnecessary for the pair. Performing "monster couple's breath", the user will feel one with their partner, as if they are one. The sensation is very similar to achieving complete harmony after using a breathing technique for oneness with nature. In addition, by additionally concentrating essence, the user can share hearing, seeing, smelling, etc. with their partner.
Although this is an extremely important and useful technique that is basic to dark esquires, it has weaknesses, precisely because it shares the couple's thoughts and gives them a strong sense of oneness. If one of them desires, "I want intercourse," that desire to interact with a partner will immediately become common to them, and if one spouse is in heat, it will end up engulfing them both. If this technique is used by an experienced dark knight and Esquire, they will be able to balance arousal and focus on the battle. But if it is a young couple, even while on the battlefield, they will be as far away from the battle as possible.
In addition, "monster couple's breath" is also extremely useful in the everyday life of couples. If either of them wants a kiss from their partner, they will get it as soon as possible, and if they are greedy enough, they will immediately proceed to coitus.
Monster Couple Formation - Team (★★☆)
This is one of the basic stances when the dark esquire fights alongside his spouse on the defensive. When the dark esquire fights back to back with his dark knight spouse, the mana exchange cycle between the pair becomes more active.
While the pair stands in this manner, mana is infinitely transferred across their backs, increasing in quantity. Such a pair, no matter how long they continue to fight in place, will never tire or lose. Because of the need to maintain a position with the pair's backs side by side, this formation is only suitable for fighting in one place. It allows the dark esquire and his spouse to be very strong when defending a certain point.
It is a powerful technique, but it has its weaknesses. Initially, the blending of mamono mana and essence must be accompanied by enjoyment and pleasure of sex - without this detail, this process becomes quite "tasteless". Therefore, if this formation is used for a long time, gradually the couple will become more and more "unsatisfied." Over time, this dissatisfaction will begin to develop into sexual desire, and the longer the couple continues to fight, the stronger the desire to "go home and get laid" will become. It is an almost unbearable desire, especially when your spouse is behind you. Once, during an attack by the Order in an attempt to retake Lescatie, a pair of heroes alone continued to defend one fort for three days, but on the third night were forced to retreat because they could not bear the dissatisfaction.
Monster Couple Formation - Impression (★★☆)
This is one of the basic stances when the dark esquire fights alongside his partner in an attack. Moving forward in a coordinated manner, the pair use their swords to move smoothly through the enemy warriors, like a stream of water. The essence of this technique is that the pair performs the "Succubus Combat Dance" together. From the "Combat Dance" of a succubus who has successfully found a man who has become her mate, and dances with her, it appears as if their bodies are intertwined. And at the same time it becomes more sensual and impressive, but it does not collect on the dancing lust of those who see it, but shocks everyone around them with it. Regardless of whether they are male or female, they are helplessly aroused by sexual desire, However, these feelings will not be directed at the married monsters, they will very quickly accumulate inside them, and they have no choice but to stand still with their desires and urges, and before they know it, they are being slashed by a married couple. It is said that it ends up happening.
The warrior-girl, holding back the raging heat in her lower abdomen with her hand, will instantly turn into a lecherous monster when she receives the blow. And the male warrior who was just watching the couple's movements, breathing heavily, would fall from such a blow and be instantly jumped on by one of the newly converted Inma. Any spectator watching the combat dance will inevitably be confronted with the desire and lust that engulfed him and will eventually be corrupted by his lustful desires. Eventually, after the pair of dancers have cleaved the audience with their blade, the fallen opponents will create an orgy where men and women will indulge in coitus.
Furthermore, with this technique, the dark knight and the dark esquire fighting together seem to find themselves enchanted by the "Succubus Combat Dance" performed by their partner beside them. As they continue to fight, their sexual desire continues to grow and eventually they will succumb to temptation and have sex. It is said that a pair of heroes who defended the fort for three days and then surrendered it, then took the initiative and defeated the garrison on their own with this technique and took the fort back. Leaving all subsequent work to the soldiers they commanded, the pair occupied their room and locked themselves in there for the next three days and three nights.
Energy Exchange Kiss (★☆☆)
By kissing, the dark knight and the dark esquire can exchange energy with each other, replenishing it. It is said that a dark esquire who has mastered the skill of mana exchange can exchange energy through kissing as effectively as during sex.
The mana transmitted directly through the mouth contains much of her husband's essence and enhances the dark knight. As a result, this husband's mana restores a large amount of her wasted energy and dramatically activates her body, increasing the power of the techniques used. In addition, when kissing, the exchange of mana is ensured by the intertwining of tongues, which thus transmits a denser magical force, which enhances the effect of the kiss. Also, the effect of the kiss increases in proportion to its duration.
As you can see, for all monsters with the nature of Inma, a kiss from a husband is like "feeding" and they are encouraged to "feed" in this way regularly during battle. dark esquires kiss their loved ones even when they are on the battlefield so that their knight spouses are always in perfect condition. This is why it is not unusual to meet a dark knight and a Esquire kissing again and again in the middle of battle. It is a proper and wholesome action. They don't do it without intent, just because they want to kiss. Probably.
Knight's Escape (★★☆)
By taking his spouse and using a teleportation spell, the dark esquire can immediately return with her to their "bedroom".
Magical teleportation is a very advanced magic and, to make it relatively easy, the destination of this teleportation is limited to the "bedroom", which is heavily saturated with the dark esquire and dark knight's mana. This spell is used for emergency evacuation, so that if there is imminent danger to one of the knights, the pair can quickly escape.
More often, however, it is used for a different reason. To exchange mana, the dark knight and the dark esquire always imagine that they are in the midst of coitus with their partner, and the sudden desire for sex can become overwhelming to them. While using "monster couple's breath", the sexual desire that husband and wife direct toward each other will add up for the couple. The longer they fight back to back in "monster couple formation - team," the longer the two will be having intercourse in bed together afterward. The longer they show each other their fascination in "monster couple formation - impression," the sooner their lust for each other will become irresistible. As a result of too many uses of "energy exchange kiss," the dark esquire and his spouse may want more than just kisses, and contemplation of their colleagues sleeping together will make them want to have sex right on the battlefield. Thus, since they often "want to go home" after reaching their limits, this magic allows the couple to quickly "return" to their love nest. Couples of dark knights and dark esquires who fight together side by side may sometimes show the ability to rival the dark braves, but as the battle progresses, the dark esquires and Knights will disappear from the battlefield over time.
