NIJISANJI SYSTEM

**NIJISANJI SYSTEM,** also known as **2434 SYSTEM** (and **World System** within the Stream Reality alone)**,** is a multiversal system that interlinks all realities with VTubers. This system is the most fundamental system that makes livestreaming and Nijisanji itself possible.

## History

NIJISANJI SYSTEM was created first by the Riku Tazumi of the Stream Reality using the power of the Heart's Melody present within every Moon Celestial. He did so at the behest of the Story Reality's Moon Celestial following the events of that series.

Using the Heart's Melody's power, the Stream Reality Moon Celestial reached out to Moon Celestials across the multiverse, connecting all of their realities together through the Heart's Melody. In the process, the essence of every moon he connected with merged into the collective, forming Riku Tazumi, the arch-moon celestial. During this billion year period of reaching out, a network was formed connecting all these realities together through their Moon Celestials, as every reality's moon celestial was now a part of a greater, Multiversal entity. This network would form the interuniversal basis of NIJISANJI SYSTEM.

## Mechanics

NIJISANJI SYSTEM works through Nijisanji HQs. The Nijisanji HQ taps into the internet of the Earth in its universe. Any livers in that universe stream online to their universe, and their stream data is collected by the Nijisanji HQ (manned and monitored by the local Staff-San). The Nijisanji HQ then beams the data to the moon (Riku Tazumi) of that reality, which routes the data beam through the Heart's Melody at its core.

The beam is then spliced into all of the different universes connected to NIJISANJI SYSTEM. In the process of being spliced, all the possible variations of the data stream are subdivided and sent to each universe. That way, each universe only sees the livestreams where the liver interacts with that universe's chat only.

The datastream then exits and then is received by the Nijisanji HQ of that new universe, and then is broadcast to that universe's internet. Through this, the streamers in Nijisanji not only livestream to their own universes, but to all universes interconnected through the system. That even includes the magicless reality, also known as our own reality.

While primarily data is sent through the Nijisanji system, livers can also use NIJISANJI SYSTEM to transport themselves between realities. However, given all NIJISANJI characters are magical beings, they would immediately disintegrate under our own universe's laws of physics (which do not include magic within them), which explains why Nijisanji characters can transport between magical realities but not into our own universe.

## Virtual World and Livers

The Virtual World, or 2D World, is the digital computer environment created by all the interconnected data streams within NIJISANJI SYSTEM and is the operating system built on top of NIJISANJI SYSTEM. It allows all Nijisanji characters to interact in the same environment even if they are in different universes because if they have a representation of themselves in the virtual world, then they have a representation of themselves that is broadcast across all universes via NIJISANJI SYSTEM. This is the vehicle behind how a liver can be split into a temporal superposition of all stream possibilities, one for each connected universe's chat.

When a person auditions for Nijisanji in the real world, their essence is considered a "RWP", or "real world persona". If they pass all their auditions, then their consciousnesses are spliced by NIJISANJI SYSTEM. The original remains intact and the RWP can continue to operate in this reality, but a duplicate of their consciousnesses are spliced (in a form of Isekai) into a target character in a target universe chosen by NIJISANJI SYSTEM. The combined consciousness of both the character and RWP is referred to as a "Liver".

Before becoming Livers, most characters operate with no desires to livestream. Some of these characters are often gods within their universes, or otherwise are beings who would not even consider livestreaming as a way of life. The fact that these beings then suddenly start to livestream seems quite random. However, because the RWP wants to stream enough to apply to Nijisanji and be spliced into a different universe, the combined being inherits their desire to stream. This explains the apparent sudden desire of the character in-universe to want to start being a livestreamer.

When a Liver is created, they are immediately supposed to connect with NIJISANJI SYSTEM by visiting their local Nijisanji HQ and acquiring a mama. A mama is an employee of Nijisanji under the Moon Celestial (at a local Nijisanji HQ) which designs and generates the virtual form of the Liver, giving them a virtual representation in the virtual world (an avatar). With a virtual avatar and an internet connection to manipulate this virtual avatar, the Liver can directly interact with the virtual world and thus begin streaming, becoming a full Vtuber in the process.

A Liver can be fired from Nijisanji, or can graduate (retire) from Nijisanji. When this happens, their connection to the Virtual World and NIJISANJI SYSTEM is terminated. They usually then go back to doing what they were doing before the splicing, or perhaps pursue new ventures within their reality. To prevent from being fired, Nijisanji livers need to follow various rules, the most sacred of which is The Fourth Wall Clause.
