Stream Reality

Stream Reality is one of the Realities in the multiverse. It is notable for not only being one of the realities connected to NIJISANJI SYSTEM, but the originating reality of said system. All Nijisanji-EN livers live within the Stream Reality. Other Nijisanji members, such as those from Nijisanji-jp, live in other universes in the multiverse also connected to NIJISANJI SYSTEM.

All Nijisanji-EN livestreams are set within this reality, and this even includes livestream adjacent material like lore videos and lore drops. This means that all lore revealed in the livestreams is an insight only into the Stream Reality. While there are many parallels to Story Reality in the Lore and most of it up to the splicing of the RWP with the characters to create the livers is the same, statements made in Stream Reality may only give some evidence as to what happened in Story Reality.

## Creation and Features

Stream Reality was created as a scission from the Story Reality where all the elements of Story Reality were duplicated over starting from the formation of the moon and continuing on into the present. Think of it like unzipping a jacket: the part at the top is the formation of the moon, and as you zip down, the one continuous line is split into two equal streams, with each stream representing a timestream in the flow of reality.

The Stream Reality was created as a result of the defeat of The Darkness at the conclusion of Arc 13. In this moment, the sudden destruction of something that can so invasively pervaded the fabric of reality itself caused reality to rend, creating the branch as a way for the universe's structure to recover and stabilize from the damage. As The Darkness had temporal nature, just like any temporal incursion creates a parallel reality or "alternate timeline", so did this event.

Unlike the Story Reality, the Stream Reality directly parallels time in the Human Reality. Down to the second, the times between the two realities run together, so 8:00 PM EST on 16 May 2021 in Stream Reality equals 8:00 PM EST on 16 May 2021 in Human Reality. The Stream Reality shares this property with most other Nijisanji universes interconnected with NIJISANJI SYSTEM.

## Events and Comparison with Story Reality

As the Stream Reality is a retread of Story Reality due to the duplication, many events and characters are the same. The key difference is that, unlike in the Story Reality, Nijisanji exists! At the moment of the scission, the Moon Celestial of the Story Reality sent a message to its newly created counterpart in the Stream Reality containing the idea for Nijisanji and also the Heart's Melody. As this was sent to the moon right as the timeline began to "unzip", it meant it was sent to the moon at its formation.

Over the next billions of years until shortly before the present, the Moon Celestial practiced using the power and setting up the idea, and eventually finished its mission. By the late nineties, the Moon Celestial had already interfaced with its counterparts in countless other realities, and all their essences had merged together to create one super, multiversal entity consisting of all these Moon Celestials, which became known as Riku Tazumi.

With this power, Tazumi was able to found Nijisanji and NIJISANJI SYSTEM, and was also able to gain immense time warping abilities, enough to create major fluctuations in the flow of reality itself. One use of this power was in containing The Darkness within the Moon itself, trapping it in time in a prison far stronger than the Ethyrium. Tazumi also used it to trap various characters (those copied over from the Story Timeline that featured in those stories) in time, eventually releasing them once they had been spliced with a RWP from the human reality to create a liver. They would then debut a month or so later across all connected universes.
