Nijika Karatachi (枳殻 虹架, Karatachi Nijika?), known as Rain (レイン, Rein?) in «[[w:c:swordartonline:Sword Art Online|]]» and «Spell Blade Online», and «Ordinal Scale» and Asanagi Hashibami (鷂朝凪, Eurasian Sparrowhawk's Morning Calm?) in «Project Alicization», is one of the main deuteragonists of Yasuda Izumi's light novel series, Sword Art Online Alternative: Spell Blade Online.

She is one of the 10,000 players trapped in the game during the scandal that was the SAO Incident. During her time as a player, she gained fame both with her already immense fame from real life along with her excellent skills in-game. She was known as the «Gray-haired Flash» (葦髪の閃光, Ashigami no Senkō?), a testament to the beautiful shade of her locks as well as her overwhelming speed.


Nijika was born in the sleepy city of Moscow, Russia. She was a mix of Japan and Russia. Her sister, Nanairo, took on more of the Russian part of the family. For the first years of her life, she lived happily. Until Nanairo's innate genius became apparent. The arguments began after that. Nijika's parents divorced. Nijika was taken by her mother to Japan while Nanairo went to America to culture her genius.

In Japan, Nijika got hooked on pop culture and had a part-time job in a maid cafe. She had quite an excellent singing voice and she longed to become an idol. In 2022, she became one of the lucky 1,000 beta testers who attended Sword Art Online's Closed Beta. She gave an extremely positive review of it and pre-ordered the game. On November of that year, she logged in to SAO again to discover that it was actually a death game. From there, she managed to solo her way through the floors until Shiota insisted that she join their party after the boss battle on the 53rd floor.[citation needed]


Nijika is a shy girl, shown in the fact that she constantly spied on the two strongest players of SAO, Shiota and Yuurei. She is also very skillful as she had managed to solo her way through Aincrad through 53 floors. After being constantly invited by Shiota, she gave in and joined her party. She liked to be complimented as Shiota was amazed that someone else could also dual-wield. Shiota apologized to her for taking the skill first to which Nijika found embarrassing. She soon began developing sisterly feelings for Shiota to which she confessed them on the 84th floor.[citation needed] Shiota received her warmly and told her that she will also love Nijika as a sister.


Nijika (ALO)

Nijika's SAO avatar as well as her ALO avatar

In SAO, Nijika's avatar was a reflection of her in real life except she changed her hair color to red, since she always wanted to have red hair.[citation needed] She always wore a white blouse with a black overcoat. Below, she wore a black skirt with gray leggings and at her belt her two swords hung.

Nijika (Pooka Avatar)

Nijika's Pooka avatar using Deadly Score

Nijika's avatar in ALO is a copy of her original SAO avatar because she had saved her final equipment to her NerveGear when the clearing raid party stormed the 100th floor. However, after the Svart Alfheim update, the ability to change races was implemented. Upon constant nagging from Shiota, Nijika agreed to delete her second account with the Pooka avatar and change her main account permanently to a Pooka avatar.


Aincrad Arc

Aincrad Hallowing

An Inkling of Evil

A flashback during the events of the 75th Floor details Nijika's life directly before and after the SAO Incident started. Nijika and Ayanami Shiratsuyu are co-recording a musical piece that will help to give Nijika a good starting boost in terms of popularity, as this is her debut piece as an idol.

After they eat a short lunch, the two girls go to Ayanami's hotel room, a suite in the lavish Keio Plaza Hotel, where they break out the [[w:c:swordartonline:NerveGear|]] and login together at the same time. They then start playing for a while, training each other while testing out the mechanics of the game itself. After six hours, they both decide to log off when they discover that they could not log out and were forcefully teleported to the plaza where they were told that they would not be able to log out until they clear all 100 floors of the castle.

When their appearances were reverted back to normal, both Ayanami and Nijika were swarmed by fans from the real world who squealed at their chance of meeting her in-game. Uncomfortable by the attention, both Ayanami and Nijika ditched to follow Kirito when the former spotted the latter running away. Through some heavy insisting, Kirito allowed the three of them to form a party and together, they went and ground through the game.

In the present time, Nijika is...
