Nano-machines

 are a collective as nanoscopic sized machines that were disseminated onto the planet that Mile was reincarnated onto.

Background
 are not permitted to give strong favor to any singular race. At most, they may rescue individuals from harm, but that is the extent of their permitted independent actions. Their primary function is to enact the desires conveyed to them via thought pulses. It doesn't matters whether those individuals are good or bad, nor whether what they desire is good or bad. The Nanos are nothing other than tools and they can achieve nothing of our own volition.

Personality

 * The each have different personalities and act differently from each other. In the anime, He tends to do fourth wall breaks, teases Adele, and gives in-world facts. He was suppose to try cute, but failing a ton, Adele decided the current form is as good as it'll get. Nano seems to know way more then they let on.

Anime

 * In the anime, looks like a floating feline creature with blond fur and magenta eyes.

Manga

 * In the manga, looks like a floating mechanical orb with two arms.

Relationships
Adele von Ascham is the only one in thousands of years to actually communicate with Nano-machines, because of this, they have a master/servant type of relationship. Nano tends to criticize her very often, since she is a very emotional, walking contradiction. Despite that they seem to have a very friendly relationship, caring for each other. Nano tends to critique the weird and unique "spells" Adele makes them do, but understands the wanted effect.

Model

 * Type NE457K-7 Prototype: Known as the 'First 3000', there were data collecting units created by the Creator and were test units used on the planet. They were given a higher degree of free will compared to all of the mass-produced models.


 * Type NE457K-7 Lot 1: Known as the 'First 7000', first mass-produced unit to be activated on the planet and charged with the 'sacred duty' of guiding all nano-machines.

Abilities

 * Proliferation - The nano-machines have the ability to multiply automatically until they have reached a fixed density.


 * Pseudo-magic - able to react to the will of living things, which causes a variety of phenomena to occur such as Chemical and physical changes. Those who don't know about the nano-machines believe that this they are using magic.
 * This is done by the user focusing their will to perform a spell and then transmit their thoughts to the nanomachines, this is called Thought Pulse Transmission. The nano-machines then make it happen, with higher thought pulse transmission ability, the greater power you have over the nano-machines making you more powerful. Although the type of power depends on your Authorization Level.


 * Nanonet - like the internet but a way for the nanos to get information or watch livestreams from the perspective of other nanos.

Trivia

 * They produced MILE-001, a robot that is operated by Nanos that looks like Adele von Ascham
 * The premise of Nano-technology not being understood is similar to how in the universe of Trinity Blood, earth was reduced to a 20th century level of technology after an apocalypse pf vampires and anything past the 21st century is considered a "lost technology"
 * Magic being a result of the nanomachines manipulating the elements is also similar to Wiseman's Grandchild, where the main character is a reincarnate with memories of science formulas in his mind; allowing him easier and more powerful use of it.
 * It is hinted that Nano knows why the world they are residing in, has no God or God-like entities watching over them. He smugly declines Adele's questions with "That's Classified"
 * A famous writer named Arthur C. Clarke once said "Any sufficiently advanced technology is indistinguishable from magic” so as the premise, we know Nano machines are super advanced, but to people in a medieval society it's "Magic".
 * Adele has made potions with Nano-machines inside them to help amplify non-magical people. if they drink them they get overwhelming power. In the real world, if we do develop Nano-Machines the main use would be to help the human body work way more efficiently. So this sort of thing has real world possibilities. Likewise using too many gives a lot of recoil once they break down in the body, which means tremendous pain as the body tries to remove the now deactivated Nano-machines.
 * It seems the emotional state of mind has a major effect on how the Nano-machines react, after all they are very logical, so if the recipient is in emotional turmoil the connection can be severely weakened. But with focus, and a clear objective a recipient can use them at an increased power, with faster reaction and command speeds. It seems that the Mind and the Will, which is the ancient concept of the Arcane in ancient literature is what the Nano-Machines designs are built off of.
