Loop System

' WARNING: This page contains spoilers for the final arc of the story.  ' is a world-scale artificial eternally repeating loop system which make of nanobots and computers, that controls the world and remakes the Earth when the world ends for the sake of preserving mankind. It was created by a research facility ran by the USA Gorverment before the first iteration.

Technical mechanism
The  make use of four major fictional technologies:


 * World remaking, especially fossil fuels and magic stones reproduction. The fossil fuels reproduction was Lene's research.
 * Soul quantization - the proccess of quantizing human souls into computer data. The idea and implemention came from Oohashi Rei's research.
 * Magic - the main technology in a "magic world", discorvered by TAIM. It make use of a clean energy source called "magic energy" which is drawn from the flow of time. Magic stones is needed to causes all sorts of magic phenomena. The core technology of the magic stones are created through radioactive waste.
 * Nanobots as workers and TAIM as the controller. TAIM was created by Claire François.

The nature of the world alternate between iterations of a "science world" and a "magic world".

When the world ends or the system starts, it enters the transition of between those two.

Firstly, "soul quantization" will begins to preserve human souls in stasis in a massive computer mainframe. All of those human beings will enter a dormant period for several centuries, while nanobots under the direction of TAIM would remake the world. Then a new iteration will be started.

Waste products from one iteration would comprise the raw materials for the next iteration. Through this mechanism, humanity could continue indefinitely on Earth, unless there’s an irreparable bug that occurs within the system.

Administrator and deputy administrator
The ' Administrator is a person which manages the ' and TAIM, with god-like powers and abilities. Although the system is mostly controlled by TAIM, there’s no way to make it fully automatic, therefore, an administrator is needed. The deputy administrator is optional.

There are three main tasks an administrator and the deputy one must handle: By its very nature, the administrator and the deputy will have an independent consciousness from the loops. While other human beings will lose their memories with each loop, they will always have their sense and our memories intact. They will conduct our management responsibilities during the transition periods of the civilizations, and aside from emergencies, they will also be living their lives in those civilizations as humans.
 * 1) Maintaining the loop system: The person would need to work alongside TAIM to control the loop system in order to keep humanity for alive for as long as possible. It also included exception handling in the event the system runs into a situation that it could not anticipate, physical maintenance and civilization stage adjustments.
 * 2) Controlling TAIM: TAIM still makes occasional misjudgments. The administrator will need to handle it in case that happens.
 * 3) Determining how long the loop will last: Suppose there’s an irreparable bug that occurs within the system and humanity is forced to repeat the loops through great pain and difficulty, the administrator is the one who has to decide it. Although this decision should not be left in the hands of a single individual.

The first administrator is Oohashi Rei. In the end of the story, she transfered her role to Claire François, make hers the current administrator. The deputy administrator's position hasn't been applied by anyone.
