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.

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.

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.
