Sense Marking
Sense Marking is a theriomancy spell described in Monster Girl Encyclopedia World Guide III: Sabbath Grimoire.
Guide Book Entry[edit | edit source]
A spell that places a powerful marking on the target's body via mana. It's cast by rubbing the caster's body against the target to stick mana to it, i.e., it's a spell that uses mana to perform the typical marking behavior of a beast. It's derived from “mana marker”, but the marking is much more assertive, and since the nature of mamono mana is utilized to erode the target's mana with the caster's mana, it's difficult to remove even when set on living targets, and the effects last for a longer time compared to “mana marker”.
This spell marks not just the target himself, but everything produced by the target including the target's mana, body odor, voice, and so on with the caster's mana so that the caster and her packmates can sense it more strongly. Monsters excel at sensing the presence of humans in the first place, but targets hit by this spell are able to be detected even from distantly remote locations, making it impossible to hide from the caster and her packmates by any means. Instinct handles target detection so that the target's location can be inferred almost like how a beast sniffs out its prey even without conscious effort.
Also, through the body odor and presence of mana, one can discern the target's physical condition and emotional state to a certain extent, and it's even possible to read the target's thoughts, and if the target is an unmarried man, it also asserts to other monsters that “he is prey being pursued by the caster or her pack” along with issuing a threat. In addition, if the one doing the detecting is unmarried as well, the effects are even greater. The bestial instinct of an unmarried female in pursuit of a male to mate as soon as she finds him will be continuously aroused by the strong sensation of the male's mana, body odor, etc., which results in the sharpening of the senses with regards to the male. In other words, not only does the target's presence become easier to sense for females, it also becomes even easier to sense for the female who longs for him.
What's more, the effects of this spell are further boosted according to one's passion for the target and desire to mate with him. This spell amounts precisely to an assertion of property rights over the male the female beast has rubbed her own scent on. Hence, if the target is the caster's husband, or her obsession and desire towards the man are so powerful that her bestial instinct has already acknowledged him as her husband, the mana and scent marking on the target will grow proportionately thicker. The caster's mana rubbed against the target issues a fierce threat to any female who approaches her male, saying “Hands off. He's mine”, and there's no limit on the distance from which the caster can sense her male. Even if he's so far away that he's on the other side of the country, or even if he's in a spirit realm in another dimension, if the female keeps running according to her instinct and intuition, she'll surely be able to reach the male.
This spell enables the target to be sensed even from a distantly removed location, but on the other hand, there is a drawback which is that if the target is the caster's spouse, and he is right by her, the sensory perception of his presence will be too overpowering. For monsters whose own husband's existence is strongly etched into their instinct, the information contained in the mana he releases as well as his voice, body odor, etc. is acutely sensed even normally. If they're made to sense it even more sharply on top of that, the stimulation will be too powerful for their mind and body, their ability to take action will be suppressed, and the bestial instinct which enables the use of theriomancy will totally malfunction. Just sniffing the overpowering male odor causes them to be attacked by a sensation like the inside of their head is melting, and the bestial instinct abandons all other than entrusting everything to the male, which causes their expression to slacken in a slovenly manner. All of the sounds released from the male's mouth, his voice as he speaks, as well as his rough breathing given the female before him, will directly jolt the female's womb, causing it to throb, even before those sounds are all processed in her head, and her bestial instinct will be dominated solely by the instinct to become pregnant with the male's offspring. Depending on the situation, she may enter a state in which she experiences so much pleasure that it's enough for her bestial instinct to trigger orgasm just from the male's scent and breath alone.
In this manner, the female will be in total submission to the male's everything, and will be unable to resist any of the sensations induced by the male. Furthermore, in this state, everything including her body, mind, and instinct abandon all other actions and thoughts, so we can even say this is a state in which she is specialized solely for “conceiving the male's offspring”, and it's said that having sex in this state may make it easier than normal to produce a child. Since there are few actual cases, it's only based on speculation, but if this is correct, then it would be extremely delightful to couples consisting of human men and monsters who have greater difficulty conceiving compared to couples where the man and woman are both human. In Beast Sabbath, which is lead by the sorcerous beast “Ropurotto”, it is recommended to actively use this spell and spend one's days mating to produce offspring in order to actually prove this theory and verify that this state does in fact make it easier to conceive a male's child for the sake of all the monsters who long to have the children of their beloved males.
