**Perfect Zero** (無下限の零 (ムカゲンのレイ)) is the Innate technique used by Kagerou Kizen, brings into reality the concept of "zero" and "nothingness" into reality, allowing the user to distort and manipulate space. Although, it is known the precise use and mastery of his Innate Technique was possible to the Todomeki (百々目鬼 (どどめき)), which was inherited through the Katsurai Family.

## Description:

"**Nullify**" or "**Nullification**" is the base state of Perfect Zero, is essentially the power to "stop" and the 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 Perfect Zero technique brings the concept of "zero" into reality allowing the user 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 techniques by neutralizing them and stopping everything in time. The ability can only be deactivated by the user, or countered by Domain Expansions, and Domain Amplifications. Although, certain Cursed Tools imbued with specialized curses can also disturb or dispel the "**Nullification**".

"**Zero-Time**" is the initial manifested form of Perfect Zero, takes the form of extremely fast brain processing speed. This is due to the Cursed Energy being routed to the brain and through all the nerves, speeding up nerve transmission and tending the time for the signals towards *zero*. This allowed Kagerou in the beginning of his career to perceive, process, analyze, understand and act upon information at an incredible rate. Although, it came with a heavy physical burden potentially damaging his brain if overused. However, through the use of a passive regeneration cursed technique to keep his brain and nerves in a healthy state. It is known that the "Hundred Eyes" plays a large role in both the manifestation of "Zero-Time" or perhaps it is due to "Zero-Time" that his Todomeki has mutated in such a way.

## Techniques:

### Cursed Technique: Void Space

The **Cursed Technique: Void Space** (術式「虚間」 (じゅつしき「キョケン」)), creates an extremely powerful gravitational point by tending the distance between a point in space and all matter around it towards zero through the inverse square law of the gravitational formula:

# F
G

m
1

∗

m
2

r
2

{\displaystyle F = G\frac{m\_1\*m\_2}{r^2}}

 Hence, as distance "r" tends infinitely close towards zero, it creates a powerful gravitational pull which bends the fabric of spacetime.
The second use of this technique is much more complicated as it requires the user to properly identify spatial coordinates to teleport. If not done properly, the teleportation may cause the user to be at the wrong spot or teleporting with missing parts of the body, effectively dismembering oneself.

### Cursed Technique: Null Space

**Cursed Technique: Null Space** (術式「無間」 (じゅつしき「ムケン」)), the technique sets the properties of fields in space and disturbances in the fabric of space as zero, effectively creating a zero-gravity and zero-magnetic field zone which will push anything out of the area. This technique thus nullifies any and all other disturbances in the fabric of space caused by opponents techniques or presence in the area as well as, ejecting them from the area. Although, it is possible to selectively chose what to eject from the field. Thus, Kagerou is capable of creating a protective forcefield around himself and others.

On another note, 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 separate an opponent in half by creating a 2D plane through the target using Null Space, which will push both halves away from each other.

### Cursed Technique: Absolute Zero

**Cursed Technique: Absolute Zero** (術式「絶零」 (じゅつしき「ゼツレイ」)), this technique sets the temperature in kelvins in an area to *zero*, thus making an area where any and all energy is absent as there is no molecular movement in the slightest. Thus, all gasses compress into solids, liquids instantly freeze into solids and all matter within the effective range of the technique freezes into place. This is also Kagerou's favorite technique in his arsenal and earned him the alias Wicked Winter (犲冬 (サイトウ)).

## Advanced Techniques:

### Note

Kagerou's advanced techniques can only be utilized once his seal has been lifted to Special-Grade sorcerer, unlocking his most powerful and dangerous techniques. But both his Maximum Technique and Domain Expansion can *only* be used once his seal has been completely lifted with the *Seal Removal Command* allowing him to utilize the full extent of his Cursed Energy and Jujutsu Techniques

### Cursed Technique Reversal: White Space

**Cursed Technique Reversal: White Space** (術式 反転「皜間」 (じゅつしき はんてん「コウケン」)), is a cursed technique which reverses the effect of Void Space. The direction of the gravitational force of the technique is reversed, which creates an extremely powerful repulsive force. Thus, essentially creating an extremely powerful explosion.

### Cursed Technique Reversal: Ground Zero

**Cursed Technique Reversal: Ground Zero** (術式 反転「地零」 (じゅつしき はんてん「チレイ」)), reverses the properties and effects of Absolute Zero causing an infinitely powerful increase in kinetic energy and temperature of the surrounding matter, causing instant sublimation of matter, evaporation of liquids and ionizations of gasses. This results in an area being turned into a miniature sun burning everything. This process is due to the direction of the mathematical limit towards zero being reversed towards infinity instead, creating a similar visual effect but a completely opposite physical effect.

### Maximum: True Zero

**Maximum: True Zero** (極ノ番「确零」 (ごくのばん「カクレイ」)), is the Maximum Technique of Perfect Zero, which applies the *Black Hole Information Paradox*, into reality. Thus, applying complete and permanent deletion of physical information. Which essentially removes from reality anything and everything in the effective range of this technique.

### Domain Expansion

**Domain Expansion: Zero Zone** (領域展開「零境」 (りょういきてんかい「レイキョウ」)), is the Domain Expansion of Kagerou Kizen using his Innate Technique **Perfect Zero**. His Domain Expansion brings targets within a true void of "nothingness" which the brain cannot even comprehend, coupled with the sure-hit effects, it is an incredibly dangerous Domain that can render opponents permanently comatose if they stay within for too long. He is only capable of expanding his domain once he fully lifts his seal.
