Anti-Kuroninja

"'I have nothing to do with Shironinger.'"

Anti-Kuroninja is the self-proclaimed “arch-nemesis” of Kuroninja. He started off as a serious threat, having been the first to win against Kuroninja in a fight, but now he’s just annoying, especially with other villains around such as Akuroninja or the Bioninja Organic Organization.

Early life
Anti-Kuroninja was born on Earth -1, a mirror Earth where everything was monochrome. The living conditions were poor there, but Anti-Kuroninja didn't mind. Suddenly, Anti-Kuroninja saw his first colour: red. This made Anti-Kuroninja curious about what was outside Earth -1, and so he left.

Meeting Kuroninja
Kuroninja, meanwhile, was fighting against a very powerful being known as Chargragigon. Anti-Kuroninja disguised himself as Chorgrogigan and lied that Chargragigon destroyed his homeworld, the Antiverse. They then defeated Chargragigon, forcing him to leave Earth 1.

However, that was when Anti-Kuroninja revealed his true self and became the first ever person in the entire Kuroninja Multiverse to defeat Kuroninja. Kuroninja then tried to stop him before he could take over the entire Kuroninja Series, but Anti-Kuroninja was too powerful due to the fact that he was a Void Ninja.

Eventually, Kuroninja defeated him with the help of his Earth-0 counterpart and exiled him away to The Void.

Cyberninja Tech Company and Return
Anti-Kuroninja wouldn't be exiled for much longer. He was found by the Cyberninja Tech Company and brought back to Earth 1 in exchange for Anti-Kuroninja joining them. Anti-Kuroninja agreed, and he now had a new Cyberninja army. Unfortunately, due to the massive amounts of anomalies caused by him before his exile, Anti-Kuroninja's power had been nerfed extremely, so Anti-Kuroninja's physical power is now very low. Due to this, Anti-Kuroninja started to rely more on his brain and magic attacks to outsmart Kuroninja.

2019
Anti-Kuroninja was mostly uninvolved with the series in 2019, until Feburary 22.

In May 2019, Anti-Kuroninja somehow became a fan of Masaki Sato from Morning Musume and started to add emerald green accents to his suit. Nobody really knows how, but one possible explanation why is because Kuroninja is a fan of Sayumi Michishige, whose initials are SM. SM backwards is MS, the initials of Masaki Sato. Somehow it makes more sense when you realize that Kuroninja has a form based on another Generation 10 member of Morning Musume whose Earth 1 counterpart is one of Kuroninja's partners.

Emerald Club
Sometime in late October, Anti-Kuroninja formed an alliance with Chiaki Tani, also known as Shinken Green, to try and get Shinken Yellow into breaking up with Kuroninja. It failed, though, because Shinken Green and Anti-Kuroninja never really met up to discuss their plans. However, Anti-Kuroninja was able to find X1 Mask from another universe (possibly Earth 10, because the Earth 1 X1 Mask lost his powers) and invited him to join forces. Together, they formed the Emerald Club.

The last member to join the Emerald Club was Sena Hayami, also known as Kiramai Green. Sena at the time was supposed to go on a date with Kuroninja, but then Kuroninja got attacked by HurricaneDark from Earth 4. At this time, Anti-Kuroninja revealed that he could channel the energy of Sakura Oda. He doesn't use that form that much because it's not green, but when he does, everyone, including Kuroninja, only has a 1 in 11 chance of defeating him in battle. It is unknown why Sakura Oda can win against Kuroninja.

Alliance with MidoNinger and supposed face turn
In 2021, Anti-Kuroninja won a contest where he could spend a day with any member of the Ninnin Girls for a day, due to buying most of the ShiroNinger merch. Obviously, Anti-Kuroninja chose to spend a day with Fuuka Igasaki, but then she got food poisoning, suspiciously on the same day as the day she was supposed to meet Anti-Kuroninja. Instead, Luna Kokonoe spent the day with Anti-Kuroninja instead. The two of them worked together to take down Sakurider, who was trying to recruit Anti-Kuroninja to join the Sakuraizer.

On Christmas Eve, 2021, Anti-Kuroninja was rejected by Shironinger. This, along with the retirement of Rena Aoi on New Year's Eve and the graduation of Masaki Sato from Morning Musume, made Anti-Kuroninja so upset that he started ranting about TokuBoy Studios.

Personality
Anti-Kuroninja generally hates everyone. He also has a very high intellect compared to other Kuroninjas. Despite his high intelligence, though, he thinks too highly of himself and believes that he's better than everyone. He's also known for being very obsessive, especially over Shironinger, to the point where he spends most of his money on Shironinger merchandise. This has stopped since Anti-Kuroninja started dating Ayu Kuroda.

Abilities
Anti-Kuroninja is known for being a terrible fighter. He makes up for it with his mind games.

Anti-Kuroninja also uses Void Ninjutsu and Force Idolization.
