Edge Of The Universe

**Edge Of The Universe** (*宇宙の果て, Uchūnohate*) is an inherited technique passed down within the Higashibojō Family. It allows the user to expand a barrier that rearranges elementary particles. This causes physics to act differently.

## Description

The **EOTU** is a technique designed with a transparent intangible barrier, this barrier allows the technique to function much more efficiently in the designated area rather than having it scatter all over. If the user is skilled enough in cursed energy manipulation they’d be able to shorten the width and length of the barrier as they would be able to control its efficacy without burning through unnecessary amounts of energy. The barrier itself imbued with the innate technique acts as artificial space.

The technique itself forces particles within the barrier to diverge and converge at a subatomic level instantaneously, this would cause the spin of necessary particles to differ significantly from what they should be, ultimately, manifesting particles that exhibit radical behavior, altering the current framework of physics. The final result of a technique can be entirely dependent on the amount of stimuli it receives if given more than enough of it. Every particle in this “universe” is almost certainly homogeneous to one another, however, aligns perfectly with how they should automatically if the particles had to birth a force that requires a complex quantum framework. Users have to be extremely cautious to prevent the loss of essential forces, which is something that only occurs if the user is in tune with the nature of this technique. This technique naturally allows the user to preserve 5 barriers operating this technique within the right prefrontal cortex of the brain. The immense burden bestowed by the parallel processing of five different techniques varying in content has killed many users, fortunately, their brains experienced forced evolution to endure the burden. Every barrier could be reset by using the Maximum technique.

Every once in a while there are users capable enough to use their techniques as a “painting on air”. This is a very esoteric technique, as it requires the utmost skill over **EOTU**. But once achieved it grants a variety of benefits, due to the fact that reality itself is the barrier the technique has no finite distance to cover so it chooses its easiest path being the body and the cursed energy, this grants the user the luxury to channel techniques within areas where their cursed energy is swollen because of the fact that the technique is capitalized on the cursed energy. The fact that the technique capitalizes on the body as well, causes the technique as a whole to undergo a surplus of output proportional to the expansion of a domain, thanks to the revelation that the body is treated as a domain. This is the ideal milestone for users.

### Cursed Technique: Daikokuten’s Eye

**Daikokuten’s Eye**(大黒天の目, *Daikokuten no me*) allows tachyon particles to comfortably exist, they act as photons and carry information. When they travel backwards in time events from the future could be seen if they were to interact with any type of lense. This could easily cause overstimulation as the information accumulates within a brain, as the user could see up to 4 hours of information in a single second.

#### Open Barrier

After achievement the user will be able to control the pace of the tachyons when it enters their brain. This protects from overstimuli. The information acquired would be clearer due to its increased definition.

### Cursed Technique: Idaten

**Idaten**(いだてん, *Idaten*) classifies mass as negative in value, this would cause all mass including negative mass to repel each other. To counter the negative mass’ repellence of its own kind a binding has been made, “decrease the repellence of mass, in exchange for attraction of negative mass”. However substances such as oxygen is repelled restricting users from extensive usage.

* **Idaten Rush**( いだてんラッシ, ュ*Idaten Rasshu*) is an esoteric technique that is produced by pouring an amount of positive energy while pouring an even higher amount cursed energy to fuel Idaten. This merges mass with negative mass, birthing a new variation of mass. This lessens inertia, giving users a massive increase in agility. Similar to Daikokuten’s eye, a binding that restricts the speed of the user to increase their physical attack has been made.

#### Open Barrier

After achievement the users’ speed increases. Due to barrier’s absence the technique would be much more effective as its concentrated solely on the body rather than being spread out within a barrier.

### Cursed Technique: Sujin’s Waterfall

**Suijin’s Waterfall**( スジンの滝, *Sujin no taki*) forces atoms to freely move rather than having it vibrate in a standard position. When solids interact with the user it liquefies. This softens the pressure from the solids exerted on the user to be greatly reduced. The higher the output, the higher the liquefaction process.

* **Sujin’s Crystalfall**( ジンのクリスタルフォール, *Sujin no kurisutarufōru*) is the **Cursed Technique Reversal** of Sujin’s Waterfall. It allows the atoms of liquids and fluids to be vibrated and fixed in a standard position causing them to turn solid. This is useful as the users gain an advantage in specific environments, such as, running/walking on water, stepping on air etc.

#### Open Barrier

After achievement, the liquefaction process will be much more effective as the technique would be concentrated on the body rather than having it spread out. This is the same for its reversal “Suijin’s Crystalfall”.

### Cursed Technique: Amaterasu’s Teardrops

**Amaterasu’s Teardrops**( スジンのクリスタルフォール, *Sujin no kurisutarufōru*) is considered a valuable technique because of the prerequisites that were required for its birth. Multiple Binding vows were made to retain certain percentages of previous particles, this process would be repeated several times before finally overlapping them, fortunately, inventing the technique. It Introduces a virtual fundamental interaction that circulates from particle to particle, the Strong Nuclear Force of matter that are foreign to its “universe” gets interrupted and cancelled, causing the nuclei of atoms to come apart. By using a “Convergence” technique inspired by Blood Manipulation, the fluidity of the CE in tandem with the substance would be compressed and released into a single point, a focused and concentrated convergence could allow for speeds on par with a Railgun to be achieved.

#### Open Barrier

The potency of it would increase due to it concentrating on the body and the cursed energy rather than having it spread out within a barrier.

### Empty Space

The 5th barrier has been left empty for generations so that the users could use the **Maximum** technique as they see fit. The user however could always utilize this “Empty space” whenever they'd like.

### Maximum: Marching To the New Universe: False Vacuum Decay

**False Vacuum Decay**(偽の真空減衰, *Nise no shinkū gensui*) is the Maximum technique of **EOTU**. It is caused by pouring a heavy pool of cursed energy into a chosen barrier, after bypassing the amount of cursed energy it could withstand the contents would destabilize as the barrier would be devoid of matter. After stabilizing the barrier it becomes a stable vacuum state causing a compact False Vacuum Decay that is restrained and dissipates after cursed energy is released. This vaporizes anything it comes in contact with within the fraction of a second. The chemistry in the affected area would fundamentally change, causing substances that come in contact to suffer severe entropy.

This causes the barrier to reset, as physics would be completely rearranged. The barrier adapts to the environment and physics goes back to normal, it would still have a chance of birthing something unfamiliar to physics.

### Movement Applications

The nature of the EOTU essentially diverges and converges subatomic particles anew, granted the skill the user could perform minor applications that allows them to change their position within space.

* **Quantum tunnelling**: With enough mastery the user could diverge and converge their own atoms without any side effects, timing the moment of convergence and applying this over a finite potential surface can decrease their particles kinetic energy so effectively that it becomes lower than the aforementioned potential surface, causing the user to phase through an object towards its other end instantaneously due to their wave function passing between the particles of the barrier. If the timing is failed the user will overlap with the surface causing instant death and a horrific sight to behold.

* **Spatial relocation**: If matter is as compatible or a certain amount of times bigger than the users’ body coordinates, and share spatial proximity, the user could force relocate their quantum positions and instantly swap spatial coordinates without causing a wave function collapse by utilizing the closed barrier variation of the **EOTU**. This application is nearly impossible to grasp as it would need close to precise cursed energy manipulation to relocate every particle safely and to distribute an accurate value of cursed energy depending on the range.

## Advanced Techniques

**Divergent: Constant:** The user could halt the convergent frame of a barrier by presetting a configuration before activation, this ensures the prolonged separation of elementary particles in a specific region. Following the equation “E = mc2”, the binding energy of former subatomic structures would release a tremendous amount of heat, generating an expanding fireball that would convert matter to plasma, creating a localized thermonuclear explosion. Thanks to the slight difference between physical constants in a barrier in contrast to reality, an explosion would be mostly guaranteed. This is likely fatal for the users themselves, which is why this is used at a safe distance away, or in an attempt at a self-destructive triumph.

**Convergent: Constant:** The user presets a configuration before activation to skip the convergent frame and immediately activate the divergent frame, in a region surrounded by materials, it would absorb surrounding particles and reconstruct it in a direction of the caster’s choosing primarily by tilting his hand in a direction to attract the construction to that region.

### Domain Expansion

Main Article: *Shattered Diffusion Realm*

**Shattered Diffusion Realm**(砕かれた拡散領域, *Kudaka reta kakusan ryōiki*) is the domain of **EOTU**, it fills matter within with a continuous stream of gamma radiation. After the deactivation of the domain it causes the aforementioned matter to be crushed from all directions with 10014 pounds worth of pressure. The user is also able to freely manipulate concepts that are applied on to trapped opponents within the domain, such as, forces, velocity etc.

## Trivia

* This technique caused the Higashibojō family’s brain to evolve.
* Every barrier originated from the Vacuum Decay phenomenon. Essentially it is birthing a vacuum that rearranges physics after its deactivated and storing it into the users brain. This cycle could be repeated 5 times before the users’ brain burst from the excessive parallel processing of heavily differing qualities.
* Many users have died before realizing that each barrier originated from the **Maximum** technique were actually being stored within their brain.
* The average brain could hold 3 techniques before experiencing symptoms such as brain fog, mental fatigue, mood swings or risking hospitalization.
* **EOTU** is energy inefficient without proper cursed energy manipulation.
* **EOTU** takes advantage of multiple Binding Vow’s.
* The outcome of the Maximum cannot be controlled.
* The Maximum technique requires a barrier.
* Tokitatsu managed to pull of an Open Barrier due to his skill over Barrier techniques in general.
* An Open Barrier is similar to an “Open Barrier Domain”.
