Epithet Switch

The **epithet switch** (異 (いみ) 名 (ょう) 替 (か) わる, *Imyō kawaru*β) is an extraphysicality centered around being able to change consanguineous blood to alter oneself. Ever since its very first incident, the practice of experimenting this specific extraphysicality was forbidden and written off as "**Rule 397.1**".

## History

The epithet switch was, possibly, the very first case of extraphysicality found back in the years of 1847 in Romania, Transylvania from experiments and tests. This extraphysicality was said to being able to change one's blood to resemble another one's own. Such as, one could possibly go from a normal family blood to an imperial family blood.

At first, the epithet switch was thought to be a disease that grew on the grounds of Romania, Transylvania, but revealed to be a non-existent invisible vapor that the Earth was growing in. This was firstly called out to be a cosmic gas or a possible fragment of a gas planet such as Saturn or Jupiter due to its purplish, orangey color.

The epithet switch was tested multiple times, with every attempts on wild animals resulting in a fail and the animal's total explosion. The animals would explode into bits and pieces in an explosion of red mist upon failing the Epithet Switch, and with their blood being the exact same type, orientation, and consanguinity even after.

The Epithet Switch, in 1859, was once tested on real humans by an organization named "Ecole Marshall". This test, renamed "Mynian Experiment", composed of 12 British women of AB negative type blood in a locked room with 12 English and American women of O type blood. The test was realized on the exact spot where the extraphysicality was found, in Romania, Transylvania. There, after being under the effects of the Epithet Switch for three days only, the women started growing more hair of different color. Eventually, their hair simply fell off, as their faces started to boil and melt from what seemed to be contact, water, and sunlight. At a point, after 10 days in, the women eventually lost any human-looking facial features such as eyebrows, visible pupils, and their skin started looking like it was boiling and bursting from the inside out, creating a skeletal layer to their skin that was retracting inside more and more.

The women were said to look like live decaying bodies boiling under the sun for days or people being thrown on top of an active glass furnace. Eventually, the women all lost their fingers due to the necrosis caused by having their skin contract said areas. And, yet again, the necrosis got to their arms, that had to be amputated to continue the test. Approximately 17 days in, the women had scrappy and stony gray skin, no hair, an inhuman amount of wrinkles all over, their mouths left lipless with their yellow teeth showing, ribs showing, strong veins pulsating from their every parts, no arms nor feet, and weighed approximately 25 kgs with a skeletal and impossibly slender build. And eventually, 24 days in, the women all died. The autopsies cited that the women had all died of an incurable disease that was then called "osseusintericomburere" in 1860, which literally translates to "skeletal inner combustion" from Latin, and was shortened to "comburis" in 1863.

The blood from the women was collected in a final attempt to witness the effects of the extraphysicality's final properties. Eventually, the blood was revealed to have been switched from human blood to a yellowish pink blood mixed with urine, blood, and forcefully extracted cerebrospinal fluid that was said to have totally grilled the white blood vessels, which created an unbalance inside the women's body, to which they miraculously survive, and which led to a complete change of appearance, mental capacity, and, at once, death.

This experiment, or rather incident, was called the "Undine In. 0915 H5 Res VI", and its results and analyses led to the overshadowing of the experiment in terms of exposure within newspapers and others after the Incident, which resulted in a mutiny in England, 1864, where the experiments were conducted.
