Kurumi Tokisaki

Kurumi is the nonexistent partner of Kuroninja’s Earth-0 Counterpart who he left Monika for. Because she has never appeared in the Kuroninja Multiverse, we only know about her from stuff that Kuroninja's Earth-0 Counterpart says. She is not here right now.

It was confirmed that Kurumi is actually Kurumi Tokisaki from the anime Date A Live, when she made her first appearance standing next to Kuroninja of Earth 0.

History
Kurumi first appeared at the end of Kuroninja Gold. She then disappeared with Kuroninja's Earth-0 Counterpart after he left Monika behind.

Kurumi wasn't mentioned until later, when Kuroninja's Earth-0 counterpart returned to the Multiverse to hear Kuroninja's announcement of when he would do a face reveal. According to Kuroninja's Earth-0 Counterpart, Kurumi has the power to control time, although Kuroninja of Earth-0 could just be tricking Kuroninja and the audience into thinking he can travel through time, when he's just controlling reality instead.

Ever since Kuroninja's Earth 0 counterpart found out about Hibiki Otsuki, Kurumi hasn't been mentioned as much as before. But that's probably because she isn't here right now. But in the Hibiki Kuroninja Tag Team Tournament introduction, she made her first appearance, or at least a copy of her did.

Trivia

 * Kurumi is from the anime series known as Date A Live.
 * Kurumi apparently has the power to control time.
 * Kurumi is not here right now.
 * One of Kurumi's special abilities is to create clones of herself. The Kurumi that Kuroninja of Earth 0 is with is most likely just a clone of the original Kurumi.
 * Before Kurumi made her first appearance in the Kuroninja Multiverse, Anti-Kuroninja thought that her last name was Tamaki, even though it was so obvious that it was Kurumi Tokisaki.
