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

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.

Rozemyne's method is highly dangerous, as over-compressing can cause hardening in one's mana pathways and even lead to death. It also increases the relative danger a person is in if they lose control of their mana.

Even at the standard classes taught at the Royal Academy, professors are present to make sure students stay safe. By comparison, the Rozemyne method takes a much heavier toll on the body, which is she insisted on only teaching those who could understand the risks.

The method is also incredibly menally taxing, according to Ferdinand: He commented that Rozemyne was likely only successful in compressing her mana to that extent due to having the mind of an adult.

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.

Students must:


 * Have already learned mana compression at the Royal Academy.
 * Sign a country-level magic contract to the effect that they will not teach the method to anyone else, even family members.
 * Have permission from Aub Ehrenfest, his first wife, the Knight Commander, the High Priest, and Rozemyne herself.
 * Pay a considerable tuition fee, a portion of which goes to pay for the cost of the magic contract. Higher-status noble are charged more for the lesson than low-status nobles. Relatives of those who have already learned the technique get a family discount.

Known students of the Rozemyne method include Damuel, Ferdinand, Sylvester, Florencia, Elvira, Karstedt, Eckhart, Lamprecht, Cornelius, and Angelica.


 * Rozemyne's commoner background helped her devise her compression method.
 * Nobles typically have servants to handle their clothing and luggage, so the concept of folding a cape for example themselves is not a concept that comes to their minds naturally.
 * Noble don't do their own cooking, and boiling is not involved in the potion-making process, so condensing liquids by boiling isn't something they're familiar with.
