Electronic Fairy

Special Artificial creatures that control the Regios. Created by alchemists as a two-way solution of having an AI performing the many functions of a Regios while having a mind of a human for maintaining and controlling the Regios, they are the most important asset of every city. Without them, the city would die. A new electronic fairy that gains new life after being 'born' will travel to seek their growth and their own city. On the other hand, the Electronic Fairy will also die if it does not have Selenium, a special ore that has many Regios fight each other for their city's survivability. An Electronic Fairy whose city has been ruined, turns into a Haikizoku, a being which is capable of greatly enhancing a Kei users power, but the user will be filled with endless hatred towards pollutant beasts.
