Rozemyne Mana Compression Method

Rozemyne Mana Compression Method (魔力圧縮方法, maryoku asshuku houhou) is a method for compressing and increasing one's mana capacity, invented by Rozemyne.

Growing up as a commoner without magic tools, Myne instinctively compressed her mana to hold off the symptoms of the Devouring. While this worked as a short-term solution, it also had the unintended side effect of causing her mana to grow at a much faster rate than most noble children.

Myne estimates that her original mana capacity was less than Dirk, a Devouring child whose capacity is roughly equivalent to a strong mednoble. However, by the age of seven and a half, her mana capacity had already surpassed those of almost all archnobles in Ehrenfest, rivaling even the capacity of Aub Ehrenfest himself.

She later shared her technique with her layknight Damuel so he could increase his mana capacity enough to court her medknight, Brigitte. The steady increase in his mana capacity even after the end of the usual "growth period" caught the attention of Ferdinand and Karstedt.

The two guessed correctly that Rozemyne was involved and persuaded her to teacher her method to nobles in Ehrenfest, as a means of ameliorating the critical mana shortage.

Functionally, the Rozemyne Mana Compression Method works similarly to other forms of compression. It involves condensing one's mana as small as possible and waiting for new mana to naturally replenish and fill the extra space. By repeating this process, a person's total amount of mana grows over time.

What makes Rozemyne's method effective is the stipulation that one should methodically "fold" their mana to fill space more efficiently, rather than try to shove it down by force of will alone. Additionally, she developed more and more steps of compression to keep up with her growing mana as time went on.

Used together, these steps allow the user to compress their mana to its farthest limit:


 * Cramming. The first step is to practice shoving down mana forcefully, like stuffing a piece of clothing into a bag.
 * Folding. After mastering forceful compression, the user imagines carefully folding their mana to take up less space, and then putting it in the bag.
 * Flattening. Once one's "folded" mana is compressed in the bag, the user flattens it, as if crushing the extra air out of the bag and leaving only the cloth.
 * Condensing. At the Royal Academy, Rozemyne devised an aditional fourth step. It requires decompressing all one's mana and starting from the beginning. The user then imagines boiling down mana like soup, evaporating the water and leaving a thick, flavorful broth behind. Once that is done, the user can repeat steps 1-3 for a more compressed end product.

This method for increasing one's capacity can be fatal, as one would be brushing against death by allowing mana to overflow; adding to another reason why noble children are given magic tools to absorb their mana and are not taught the method until attending the Royal Academy. It is also incredibly strenuous, according to Ferdinand: he commented that she was likely successful in compressing her mana due to having the mind of an adult.

. By forcing mana from the rest of their bodies back into the mana-storing organ, mana-users can compress their mana into a higher density, allowing them to gain a larger mana-capacity, since they can store more mana in the same amount of space so to say.

For adult's who's body has already stopped growing, this will only affect the density of their mana, but if this is done by someone still in their growth phase, this will cause their mana-storing organ to grow faster than it otherwise would.

First simply having mana above a certain amount dispersed around the body, which is a necessity to compress it, carries risks of it's own: It will stunt the physical growth of the body and depending on the emotional state of the person can go out of control, which can result in others around the person being "crushed" by the mana or the mana harming the body, usually in the form of high fevers, though in extreme cases this could even mean exploding parts of the body. For these reasons nobles do now allow the mana of their children to build up, but instead give them magic tools that constantly drain their excess mana.

How much a person is able to compress their mana is a combination of how well suited their mental image is and their willpower. If the mana is compressed too much in too short a timeperiod, it can lead to headaches, dizzyness and nausea similar to a strong hang-over.

Because of the danger of the method, and because of its potential to drastically increase the mana of the user, Rozemyne decided on a selection of criteria to decide who she would teach:


 * Only people who already learned mana compression at the royal academy are eligible.
 * Applicants need to sign a country-range magic contract preventing them from passing on the technique to others, even family members, unless they too have already been taught the technique.
 * To be taught requires the permissions of Aub Ehrenfest and his wife, Knight's Order Commander Karstedt, High Priest Ferdinand and Lady Rozemyne.
 * A stiff cost needs to be paid depending on status. The higher in status, the more a noble will need to pay. Those who have relatives who already know the technique get a discount.
 * Part of the money will go to Ehrenfest's treasury to pay for the magic contracts.


 * The reason why no other noble before Rozemyne seems to have ever thought of using such seemingly simplistic clothing-related mental images is because nobles have servants taking care of their clothes from birth, thus the concept of folding a cape for example themselves is not a concept that comes to their minds naturally.
 * Similarly, no one thought of the boiling method because it's not a common practice when concocting, and nobles won't be cooking food on their own.
