Riku Tazumi

**Riku Tazumi** is the creator of Nijisanji and NIJISANJI SYSTEM. In the Human Reality, he is just a normal CEO, but his form serves as the template of a Celestial entity with the same name made from the collective Immaterial Essences of countless Moon Celestials across the multiverse, which makes it one of the most powerful beings in the multiverse except for the embodiment of the multiverse itself.

## Etymology

As mentioned, the Riku entity derived its name from a human living in the Human Reality. It is unclear why this particular human was selected by the entity, but then again nobody knows the mind of such a powerful creator.

## History

After the destruction of The Darkness in the Story Reality, the Stream Reality began to split from the parent timeline in a form of temporal incursion. During this moment, the Moon Celestial from the Story Reality sent the idea for Nijisanji as well as the power to make it happen, the Heart's Melody, to its counterpart in the new reality.

As this new reality began writing itself at hyperspeed from the moment of the moon's formation, the moon had billions of years to learn to use the immense power it held and carry out the plan it had been given. This succeeded by the 1990s of the Stream Universe. By then, the original Moon Celestial had reached out to countless other moon celestials in countless other realities.

Then, in the 1990s, all the Immaterial Essences of all the Moon Celestials within this network (later named NIJISANJI SYSTEM) combined to create one singular arch-Moon Celestial entity, the entity known as Riku Tazumi. Around this time, the human with that name was born in the Human Reality and the entity took his form and also anointed him to found Nijisanji in that reality. NIJISANJI SYSTEM and the Virtual World were soon made possible and Tazumi was able to found Nijisanji in 2018.

Riku Tazumi would later use his vast powers to create powerful time bubbles, including one to trap the Darkness in the Stream Reality, and also ones to suspend characters until they are ready to be merged with an RWP from the Human Reality. After that, they become a liver and can debut for Nijisanji and begin livestreaming content to the rest of the multiverse!

## Appearance and Personality

Riku Tazumi in its base form is formless. However, he has taken the form of Riku Tazumi from Earth, a young Japanese man. He is commonly seen against a white background and with a white t-shirt when interacting with those who visit him and seek an audience with him.

Riku Tazumi is an immensely caring individual, although he is often aloof and rarely involves himself in trivial matters. However, he is not above stepping in when problems arise within Nijisanji, and every so often when a joke is to be made. However, Riku is often unrelenting when certain rules of his are violated. One such rule he holds as a hot button is the Fourth Wall Clause. When a liver violates this rule, Tazumi often becomes unbudging and may even request the liver graduate depending on the severity of the breach. His main goal is Nijisanjification, which while it gets a bad reputation, is in its truest form a testament to Tazumi's desire to bring people together.

## Powers and Abilities

Riku Tazumi is the collection of countless Moon Celestials across countless realities. Even though an individual moon celestial is on the lower level of Celestial power, this power very quickly adds up when one considers the infinitude of the multiverse. This power is amplifed further due to Tazumi's possession and mastery over the Heart's Melody, the beating heart of reality itself. It is commonly believed that so many realities have been visited by Tazumi, and so many moon celestials absorbed, that Riku Tazumi is the second most powerful entity in the entire multiverse, behind only that of the embodiment of the multiverse and keeper of the Heart's Melody itself, the Universe Celestial.

Time Bending: Tazumi possesses almost boundless Temporal Manipulation magic abilities, being able to warp the Flow of Reality in any way that he sees fit. This includes his ability to generate bubbles of stopped time that can even contain The Darkness, one of the most powerful threatening forces in the entire multiverse. He can also travel in time with ease, manipulating past events in light of future ones, which can be used to help line up RWP and character experiences. Tazumi is also the ultimate source of isekai, even allowing him to extend his influence into the typically magicless Human Reality. He is able to do so by controlling the Heart's Melody to get the Universe Celestial to infringe its essence upon that universe to create small patches with intersection points with universes with magical laws of physics, which enables even the Earth's moon in that reality to participate in NIJISANJI SYSTEM.

Universe-Level Power: Tazumi exhibits powers to do absolutely anything he desires up to a universal level and possibly even above that, giving him limited omnipotence within that frame.
