Kuroninja of Earth 0

"'Reality can be whatever I want.'"Kuroninja’s Earth 0 Counterpart, whose real name is unknown, is the creator of the Kuroninja Multiverse and the most powerful Kuroninja in all of the Kuroninja Multiverse. He has a lot of powers, yet nobody cares about him. The form he takes when he enters the Kuroninja Multiverse is an avatar used to interact with the characters of the Kuroninja series and it's not how he really looks like.

History
Nobody knows exactly what the Kuroninja of Earth 0 was like before he created the Kuroninja Multiverse, but he's good at writing, or at least he has enough confidence to claim that he is. Like most of his creative works, the Kuroninja series and the character known as Kuroninja was inspired from a dream he had.

Kuroninja of Earth 0's first interaction with his Earth 1 counterpart was when Kuroninja of Earth 1 was just starting. Kuroninja of Earth 0 made his appearance in the guise of Chargragigon, Guardian of Anomalies, who introduced himself as an enforcer of the Rules of the Kuroninja Multiverse. However, Kuroninja defeated him with the help of another being named Chorgrogigan. However, Chorgrogigan was actually evil and revealed himself as the Anti-Kuroninja, who was from Earth -1 (also known as the Antiverse).

After Anti-Kuroninja defeated Kuroninja, he sent him to Earth 0, which looked like a dark void but was actually the basement of Kuroninja of Earth 0's place, which was dark because there was no light. Kuroninja of Earth 0 then properly introduced himself to Kuroninja of Earth 1 and sent him back to Earth 1 to defeat Anti-Kuroninja and send him to The Void. Obviously, Anti-Kuroninja returned from the Void.

Later, the Kuroninjas of Earth 0 and Earth 1 started to hate each other after a computer virus destroyed most of Kuroninja's work. Kuroninja of Earth 0 also started to get bored of the multiverse he created, so he decided to invite Monika, his waifu girlfriend at the time, to the Kuroninja Multiverse. Monika also brought her friends from her book club with her, including one who would later become the most controversial being in the Kuroninja Multiverse. Kuroninja of Earth 0 knew that Monika could delete anyone in her game, so he used his executive powers to limit Monika's ability to delete stuff. He still loved Monika, which led to him protecting Sayori and giving her the power to win against Kuroninja, making her one of the few who could always win against Kuroninja.

In August 2019, Kuroninja of Earth 0 turned on Monika and found a new waifu partner: Kurumi Tokisaki from Date A Live, the first anime that Kuroninja of Earth 0 ever watched in his lifetime. It is unknown if this is the real Kurumi, one of her clones, or a puppet created by Kuroninja of Earth 0 through his power of creation. At this time, he also became a fan of Hibiki Otsuki, which led him to give himself the title of "Hibiki no Ouja."

As Hibiki no Ouja, Kuroninja of Earth 0 became slightly more evil, with Kurumi at his side. On September 2020, Kuroninja of Earth 0 confirmed that his partner was, indeed, Kurumi Tokisaki from Date A Live.
