Guide Book Entry[edit | edit source]
“Spiritish oath” is a spell used by elementalists when forming contracts with the “pure spirits” that exist in the natural world. A mana link between the elementalist and the spirit is required when forming a contract with a spirit. This spell, which is cast using a Spiritish incantation, communicates one's will to form a contract with a spirit and performs a mana exchange to establish the link. When this spell is cast on a spirit, a contract will be formed should the spirit agree to it.
The link required to use elemental magic can also be made naturally over time by staying in contact with a spirit. Even without a formal contract, if one deepens engagements with a spirit, the spirit will lend him its power, so this spell is not necessarily even required for using elemental magic; however, “pure spirits” have neither a body, nor a gender, nor a solid sense of self and are therefore extremely vague and unstable entities. Not only do they have unstable forms such as flickering flames or relentlessly shape-shifting masses of water, so too does their very existence itself lack stability. Unlike ordinary living things, their existence isn't firmly established. On top of that, their relationship with the elementalist would also be something vague and volatile, which means that he would have no idea whether or not he'd even be able to borrow power from the spirit until the moment he used elemental magic. Unfortunately, spirits may at times suddenly fall asleep or go elsewhere without warning, so the stable usage of elemental magic would be impossible. That's why this spell is used to stabilize the existence of an unstable spirit by clarifying the relationship between the elementalist and the spirit via giving the spirit a role to fill as a servant of the elementalist. Once they officially have the relationship of contractor and employed spirit, the aforementioned problems naturally disappear and it becomes possible to stably borrow power, although it does still depend on the spirit's mood.
On the other hand, one can form a contract with a “monster spirit” using one's own body to swap mana and establish a link by becoming physically intimate and engaging in sexual intercourse. What's more, the elementalist needn't even rely on this spell, since by transforming into a monster female and obtaining both a body and a gender, the monster spirit becomes a stable being, and the physical act of sexual intercourse establishes an extremely powerful relationship between the contractor and the employed spirit, that of “lovers” or “husband and wife”, thereby enabling the use of elemental magic.
Additionally, the incantation used to cast this spell has the meaning of a “marriage proposal“ in Spiritish. As previously mentioned, this spell isn't absolutely necessary for forming contracts with monster spirits or dark spirits, but having become monsters, they gain a clear self-awareness as women and will acknowledge human men as the opposite sex, so for them, the meaning of these words becomes extremely important. Even when forming a contract with a monster spirit, just like with pure spirits, it is necessary to acquire the spirit's consent, and that's where these magic words come in handy as a reliable method to make it far more likely to happen by sending a powerful jolt through the spirit's heart and making her acutely aware of the caster's existence. Moreover, it tends to exacerbate a spirit's obsession with her elementalist, so the relationship and the sex will easily become deeper and more intimate afterward. Also, if the caster forming a contract with a spirit using this spell is an incubus or monster, by performing the mana swap, mamono mana will be poured inside the spirit, which will therefore result in transforming a pure spirit into a monster spirit.
No matter what, this spell is only a means of proposing a contract to a spirit. One cannot ignore a spirit's will and force her into a contract. For that reason, when forming a contract with a spirit, it is crucial for the caster to have an affinity with the spirit and spend time interacting with her to build a trusting relationship. If contracts are formed with spirits of several different attributes, then one will become able to use elemental magic of the corresponding number of attributes, and if multiple contracts are formed with spirits of the same attribute, then the potency of the elemental magic of the corresponding attribute will be even further increased, so one can increase one's power as an elementalist by leaps and bounds by contracting multiple spirits; however, when multiple spirits are contracted, squabbles over the contractor will occur among them, so it is generally considered to be extremely difficult from the second contract and on.
This is particularly so in the case of monster spirits, who are deeply enamored and obsessed with their contractor. They will practically compete with each other to pour more power into their contractor and prove themselves the most useful to get attention from him, and will at times go berserk, becoming uncontrollable. When the spirits' power becomes too much for the contractor to handle, it will end up being used according to the desires of the spirits. The power of fire will make the contractor's body flush hotly, the power of wind will disturb the contractor's thoughts, causing him to be consumed by maddening lust, the power of water will make his heart drown in peaceful pleasure, and the power of earth will make him produce endless amounts of semen and mana. Those with multiple spirits of the same attribute in tow will drown in the magnified power, while those with multiple spirits of different attributes will just be tossed about by the chaotic mixture of power. Spirits gone wild will drag away their contractor, and he will end up having to spend his life getting milked while having sex with them one after another or all at the same time.
In this manner, when leadership is robbed away by spirits, or rather, sex-crazed monsters, wielding elemental magic will be out of the question. Elementalists capable of wielding high level elemental magic of multiple attributes are extremely rare because they'd have to make love with and satisfy multiple spirits without being dominated by the pleasure and power continuously poured into them by the spirits. In most cases, elementalists who continuously deepen a bond with just a single spirit and master a single attribute will have far greater proficiency than those who barely managed to contract multiple spirits and wield the four elements while being at the mercy of multiple spirits. For that reason, most elementalists usually limit themselves to contracting only a single spirit. The ability to control multiple spirits at will is restricted to those with an exceptionally rare gift for elemental magic who have the capacity to subdue multiple spirits, and those who continuously put effort into extraordinary research. In particular, the total number of elementalists in the world who have subdued all four of the primary elements, fire, water, wind, and earth, is so small that it's countable.
