Delta

**Delta** (δ), also known as "**Mm/h**" (megametre per hour), is a distinct concept of a different matter of speed. It is named after the letter fourth letter of the Greek alphabet, **Delta** (Δ). In the system of Greek numerals, **Δ/δ** has a value of 4. In the metric system, Δ/δ has a value of 1 megametre.

## Formula

### Δ𝑣

Delta is a scalar that appears to function over particles of kinetic energy shocking and colliding with each other repetitively in partially divided areas that grow greater and greater as it goes. Normally, Δ𝑣 is used in spacecraft flight dynamics. It is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon or an in-space, orbital maneuver. However, it was shown to be present in the matters of **Delta**. A diagram shows a singular step displaying minuscule barriers of different kinetic energy that trailed from the foot to its landing point. As logically taught, kinetic energy multiplying itself by two would generate a flow in which any atom passing through it would speed up by approximately four times over its original speed. Once reaching around 317.3333334 metres per hour, Δ𝑣 occurs. By meaning, Δ stands for a change, while 𝑣 stands for velocity, totaling to a change in velocity. For example, if going at an approximate 100 mp/s while possessing 150 mp/s of Δ𝑣, turning a certain side would cause the Δ𝑣 to add itself to the active speed, making up for an approximate 250 mp/s. If repeated, the phenomenon repeats as well.

### 𝑣

In velocity, δ is infinite. No matter how fast an object or being goes, Δ𝑣 always follows, regardless of the impossibility of that speed. While the thought may be illogical, Δ𝑣 would be similar to riding a car at maximal velocity while trailing along a quicker one similarly going at maximal velocity, albeit unable to trail along the slower one.

which is simply the magnitude of the change in velocity. However, this relation does not hold in the general case: if, for instance, a constant, unidirectional acceleration is reversed after (t1 − t0)/2 then the velocity difference is 0, but delta-𝑣 is the same as for the non-reversed thrust.

## Mora's Use

* **Gatesface.** (ゲート。, *Gēto.*β) - Utilizing **Delta** to its secondary degrees of disintegration from an overly quick speed, Mora is seen capable of entirely changing dimensions from his to another dimension. This is seen when he mistakenly travels to another dimension that is not part of the series — what he was described by a "mentally ill chick" to be some type of future or 'whatever'. In another dimension, he met a "punk-ass redhead" who asked him whether he was a "devil" or not, which annoyed him, and told him about a certain "simp", who he called a "lame-ass blondie". And in yet another dimension, he met up with a "zombie" who he says looks like Medusa. In addition, he had also heard of another Medusa from a "pink-haired mental".

* **Emition** (排出 (はいしゅつ) , *Haishutsu*β) - Using Delta, Mora is capable of seeming to move in a way that suggests that he may be teleporting. While most people, and even himself, call this "cheating", he seems to have fun activating barriers from Allrakinēsia to stop people from running.
