Contract of Obedience
'Contract of Obedience is a nymphomancy spell described in Monster Girl Encyclopedia World Guide III: Sabbath Grimoire.
Guide Book Entry[edit | edit source]
A spell that forces the target to obey with pleasure. It is one of the spells that once made inma dreadful horrors to humans when they used to fight monsters in the age of the former mamono lords. The spell is invoked by having intense sex with the target, enthralling him with inma pleasure, and along with that, binding a powerful contract which would state, “the target will be pleasured by the caster if he takes the specified action.” Those who have become enthralled by inma pleasure prioritize obtaining more of it over all else, and become willing to do anything to get it, so the caster is able to control their actions as she pleases. It is said that with this spell, the inmas of the age of the former mamono lords used the humans under their domination to set traps to destroy humanity, and carry out sinister plans given to them by the mamono lord. Thus, it is an extremely terrifying spell, but it no longer exists in the present due to various reasons, and the spell has now been lost.
There are various reasons why it has been lost, but it mainly has to do with the changes in monster ecology, monster thinking, and the alteration of the nature of mamono mana. In particular, a direct factor is that the invocation of nymphomancy spells is based on the caster's “desire”, and spells that run contrary to that desire cannot be used. “Sex” and “pleasure” were nothing more than a means of attacking and preying upon their human male victims to the inmas of the age of the former mamono lords. That's why they were able to mercilessly use “contract of obedience” for their villainy in the ways that they used to. On the other hand, to the inmas of the present, “sex” and “pleasure” are not just a means of obtaining essence. Instead, intercourse is the most powerful expression of their love for their partner, and pleasure is something to drown in together. While they give it to their husband so that he feels good and is pleased with them, they themselves also enjoy receiving the pleasure given to them by him. What's more, to inmas, sex is fundamentally something that they want “immediately all the time.” As far as they're concerned, they want to be getting off on pleasure provided by their husband at every given moment. Therefore, the act of attaching conditions to sex would just be tedious and idiotic to inmas precisely because of how badly they want their husband, and thus, they are no longer able to use “contract of obedience” since it is greatly detached from the “desire” they embrace.
Furthermore, “demons”, which are the fiends who used to lead humans to destruction, are still fussy about their time-honored fiendish ways even now. They corrupt men and propose contracts “promising eternal pleasure in exchange for offering up everything to them.” And yet, still, for a man to offer up “everything”, means for him to stay beside the demon and live with her, direct his pleasure and lust towards the demon, seek pleasure from the demon's body, pour his essence inside the demon, and impregnate her. Ultimately, a demon's contract boils down to “a promise of eternal pleasure by becoming her spouse for eternity”, which is something close to a human “marriage contract”. It is similar to, yet different from a “contract of obedience.”
Also, another big factor is that mamono mana, which exhibits more power if used in accordance with desire, is, on the other hand, endowed with an extremely high resistance against spells which force someone to do “something that is contrary to desire”. In the present era, the men enthralled by inma pleasure who would be targeted by “contract of obedience”, are in other words, those who have already had sex with inma and become their husbands. They may already be incubi, but even if they aren't yet, they would still at least have mamono mana in their bodies. Due to the resistance conferred by mamono mana which blocks magical effects that greatly contravene men's desires, nobody would try a method like “making him ambush his fellow human allies in exchange for pleasure”, and even if they did, it would have absolutely no effect. In this way, it's not that “contract of obedience” “can't be used because it was lost”, it's that it's a spell that “was lost because it can't be used” in any conceivable manner.
