Turn Null

**Turn Null** ( *ゼロになります Zero ni narimasu***?**, lit. "Return to Zero") is the ability that is exclusively used by one Academy City's Level 5 Espers, Rei Hajime.

The ability brings the concept of "zero" and "nothingness" into reality, allowing the user to distort and manipulate space.

## Principles

Rei's ability works by assigning objects and phenomena a numerical value and then defining said value as "Zero".

Via precise calculations and manipulation of space at an atomic level as well as points in time through laws of general relativity and quantum mechanics, the ability can tend variables in a formula towards zero or even define the variable as zero.

### Nullify

**Nullification** is the base state of Turn Null and is essentially the power to stop everything and anything, it is Rei's most basic defensive system. It operates by defining every force, motion, action, and other as a "duration-less" instant of time. However, in mathematics, a number will never reach zero no matter how many times it is divided. Instead, there be infinitesimal small fractional units, it becomes immeasurable by any known means. The ability literally brings the concept of "zero" into reality allowing Rei to define things as "zero" or tend them infinitely close to zero.

Thus, the "barrier" created by "**Nullify**" is a result of the application of "Zero" to the duration of an action or movement and bringing into reality Zeno's Arrow Paradox, and can be expanded or receded to protect against harmful substances or overpower opposing abilities by neutralizing them and stopping everything in time. The ability can only be deactivated by Rei, or countered by abilities such as Imagine breaker.

### Turn Null

**Void Space**: The form of Turn Null which affects the value distance between a point and a designated area creates an extremely powerful gravitational point that can be shaped at will depending on the shape and size of the designated area. Although, it is currently unknown how large the field can become, as the largest area of effect shown has been the size of a Football stadium. Through the use of the gravitational formula:

We see as the variable of distance "r" tends infinitely close towards zero, the force "F" becomes infinitely larger.

If a physical body, such as that of a human were to be struck directly by the technique, they would most likely instantly implode into themselves. However, precise use of the technique can lead to dismembering or crushing certain parts of a target to render them incapacitated or unable to battle. This technique appears to form a distorted sphere, as space distorts more and more heavily closer and closer to the epicenter of the gravitational pull.

Another use of this technique is teleportation, although the distance voided is proportional to Rei's own calculations. This teleportation works as well on distance, except it is the distance between the user and the target location which is turned to null. Thus, Rei only needs to take a single step to reach his destination.

**Null Space**: Rei sets the properties of fields in space and disturbances in the fabric of spacetime as nonexistent, effectively creating a zero-gravity and zero-magnetic field zone which will repulse anything out of the area to keep the absolute zone of nothingness. This ability thus nullifies any and all disturbances in the fabric of space caused by the opponent’s abilities as well as, ejecting them from the area. The affected area of this ability turns mirror-like, as all light is sent back through its trajectory.

Although, it is not possible to selectively chose what to eject from the field. Then, if the undisturbed fabric of space-time is not shaped to surround them, using the technique protective forcefield around himself and others poses issues. Hence, Null Space can take a variety of shapes, such as walls, cubes, spheres, and others, to take on a variety of uses. Though it is used most often as a defensive technique, it can be used offensively as well. One offensive use is to cleave the opponent in half by creating a place through them using Null Space, which will push both halves away from each other.

A side effect of the zero disturbance field of spacetime, the *immediate* surface which comes into contact with Null Space instantly enters a state of Absolute Zero temperatures, although the rest of the mass is left unaffected. This is caused since energy and mass affect the fabric of space.

**Absolute Zero**: This form of Turn Null which affects the energy in a designated area or object, sends the temperature or molecular kinetic energy of any particle to absolute zero or 0 Kelvin. This ability initially takes the form of a foggy white imploding mass in the desired shape of the area of effect. Once the mist has dissipated a 0-kelvin area with a complete absence of any molecular movement is formed, this has the effect of compressing all and freezing all liquids and gasses into solids and halting any type of molecular process within the effective range of this technique.

With complex and precise calculations Rei is able to "select" only solid and liquid states of matter to freeze and leave breathable air within the atmosphere. Although, this increases the technique’s cast time it also allows Rei not to destroy the immediate environment.
