## Stream Reality Timeline

4.5 Billion Years Ago: The timeline splits from the Story Reality and begins to "unzip" back towards the present as time flows at a hyperaccelerated rate compared to how it flows in other universes until it reaches the present. The Moon forms and the Moon Celestial in this reality receives the idea for Nijisanji, as well as the power to make it happen via the Heart's Melody, from the Moon Celestial in the Story Reality.

1990s: By now, all events have happened exactly as they did in the Story Timeline, except that the moon has been working in the background, honing in its power with billions of years of practice. By networking with countless moon celestials across countless alternate realities, all moon celestials were merged together into one unbelievably powerful entity, and Riku Tazumi was born.

2000s: Riku Tazumi traps the Darkness in a temporal chamber much stronger than even the Ethyrium, and begins trapping characters in time bubbles to save them for when he needs to splice them.

2018: Riku Tazumi officially implements his billion year plan and founds Nijisanji and creates the Virtual World that runs on NIJISANJI SYSTEM, the system created by the network the moons have been creating across the multiverse for the past billions of years. People in the Human Reality are given a chance to experience magic by being isekai-ed by NIJISANJI SYSTEM, splicing their consciousnesses into a reality with magic where they become one with a character as an entity known as a Liver. This begins happening in select universes across the multiverse.

2021: NIJISANJI SYSTEM officially begins splicing consciousnesses into the important and crucial figures in Stream Reality's history (parallel to that of Story Reality), creating NIJISANJI-EN. Riku begins his plans to remove the rest of the taint of the Darkness from this reality.

Early 2022: Rosemi's battle with Diablo Jim occurs in this timeline as part of Riku's mission.

Later 2022: To remove the taint of the Darkness from the Ethyria Project reincarnation cycle and allow it to be reborn and renewed, Tazumi anoints the four members of Ethyria as queens of differing aspects of the universe, an idea inspired from a cosmetic theme originated by the members. Reimu's memories are restored and she becomes the Queen of Hearts, the Queen of Souls in Hell. Millie regains her full power and is anointed as the Queen of Clubs, the Queen of the Timelines. Enna is given control over her dark tendencies and is anointed the Queen of Spades, the Queen of Love. Lastly, Nina is anointed as the Queen of Diamonds, the Queen of Luck.
