Rapture

**Raptures** (ラプチャー, *Rapuchā*), otherwise known as **Eclipses** (エックぃぷす, *Ekku~ipusu*) or **Constructs** (コンストラクト, *Konsutorakuto*), are a race of powerful mechanical creatures. They are humanity's greatest enemy and are currently the dominant species of Earth.

## History

The origin of Raptures was initially largely unknown. Humans either believed Raptures were aliens from another world, a result of their own technology, or an act of God. Raptures began their appearances during the Rapture Era, effortlessly slaughtering humans, dwarfing the global population, and pushing humanity to the brink of extinction. But with the rise of Silver Defense Front, and subsequently, Anti-Disaster, Rapture attacks were halted, leaving both sides in a deadlock.

It is later revealed that Raptures were sent from an alternative future a thousand years from the modern era. They were constructed by Kali after she had come in contact with a strange Umbras Cube. They were created for the sole purpose of exterminating humanity and any other life form in their way. Though they successfully eradicated all life on Earth and left Kali as the last human, she came to discover that her Earth branched off from the original timeline due to the arrival of the strange Umbras Cube. Seeking to truly wipe out humanity, she sent her Raptures a thousand years back into the original timeline, beginning the events of the story.

## Physiology

Raptures are completely mechanical, possessing durable metallic chassis and carapaces dubbed "Material-E". Many limb-like structures are seen as black interwoven fibers and metal tubes, simulating muscle tissues and bones. This lets Raptures, upon creation, shape themselves into the forms of Earth's creatures, including mammals, reptiles, and arthropods.

Rapture bodies are extremely durable, capable of withstanding kinetic forces, high temperatures, and to some, nuclear radiation. Thanks to their mechanical build, Raptures can also utilize bodily weapons such as high-frequency blades, rockets, and laser cannons. It is believed that, the bigger the Rapture, the more weapons and raw power it may possess.

All Raptures possess a "core", a singular source of perpetual energy that powers their entire bodies. Cores are weighted spherical objects that emit a faint white light due to the circulation of electricity. Other than being the main power source, it is the function of the core to charge Rapture weapons before they can be fired. Worldbreaker Raptures, however, have up to three cores to power their massive bodies and distribute a chaotic amount of energy evenly. The core is the weak spot of all Raptures and striking them with enough force will completely neutralize them, often causing their bodies to explode. But as long as the core is still intact, Raptures can still fight and repair themselves.

## Behavior

Raptures are extremely hostile against non-Rapture creatures, mainly humans. Being sentient machines, Raptures possess no remorse or regret for their actions, knowing only to attack relentlessly. Upon engaging a human or threat, an Rapture will let out a deafening mechanical screech. They are also tactical, knowing when and how to engage, as well as knowing when to retreat if needed.

Among themselves, Raptures are more passive in nature, similar to animals in the wild. It is possible to disguise oneself as an Rapture and monitor their behavior. This indicates that Raptures can only distinguish between allies and enemies from looks alone.

Raptures are also capable of sleeping. This is crucial for letting their cores recharge after extended usage. They cannot be woken up from this state other than tampering with their cores directly, which will alert the Rapture instantly.
