Delta (デルタ, Deruta) is an "Inner" from the organisation Kara.


Delta has a short temper, which makes her destructive at times, such as kicking a table that her leader was eating at to vent her frustrations. She is very focused on missions, getting visibly irritated when they are not completed within the expected timeframe. Jigen mentioned that she has been worried about her weight previously, which indicates that she cares about her appearance.

She also appears to be quite impatient, growing angrier and angrier when Koji was taking too long while looking for Kawaki in Konohagakure. She's also seemingly confident of her own abilities, openly confronting Kawaki while in the company of the Seventh Hokage and being unfazed while standing face-to-face with him.


Delta has blonde long, curly hair and light brown unusual eyes, with vertical lines running along the irides. She has a green tattoo of the Roman numeral Ⅰ in the centre of her forehead. She wears a black and red cloak and a turquoise blue outfit with, an exposed heart shape cut on her back, cut-out bishop sleeves and white wrist cuffs, red triangle earrings, black and red striped tights, and white long high-heeled shinobi sandals. She also has yellow lipstick and matching nail polish on her fingernails.[1]


Delta's body has been enhanced greatly by Shinobi-Ware to an even seemingly greater degree than Ao's were to the point where she had become a full cyborg. On her back, she keeps a drone for spying purposes, which can go through the normal chakra barriers around villages undetected since it doesn't use chakra. Not only that, she can modify her legs for high-speed travel, creating practical rocket legs similar to those used by the Asura Path.[2] Her modifications also grant her tremendous raw strength, able to casually grind her fingers through the trunk of a sturdy tree.

Delta & Koji

Delta and Koji arrive at Konoha.

During dinner with Jigen, Delta was concerned about Koji Kashin trying to retrieve Kawaki. After listening to Jigen's reasoning, she angrily kicked away the table and demanded to know the leader's explanation for how long the vessel's recovery was taking. Delta later received permission from Jigen to check on the mission's progress herself, and report back to him if there are any issues. She joined Koji from afar and was asked by him if she brought an Outer which she confirmed that she brought Garō to retrieve Kawaki. She watched as the defiant Kawaki attacked Garō. Delta was also surprised to find out Boruto Uzumaki has a possession of Kāma. After Kawaki killed Garō and fainted from overheating, Delta felt it would be a good time to get rid of the Konoha-nin and retrieve Kawaki. Koji argued that Boruto having a Kāma warranted further observation before taking action, and that with the blimp crash, it was inevitable that the world would learn of Kara's existence. Later, she and Koji arrived at the main gates of Konohagakure to retrieve Kawaki.

Delta stated that it would be difficult infiltrating, but despite her statement, she was told to stay put by Koji, who entered the village without setting the barrier off. Much to her dismay, she believed that Koji tricked her so he could continue the mission without her surveillance. Growing impatient with Koji not returning and being in a angrily mood to kill someone, she launched a drone from her back as it could bypass Konoha's barrier without being detected, and requested it to locate and inform her of Kawaki's whereabouts before it flew off. When it found him training with Boruto, she entered the village's airspace, during which her presence became known to the village's sensory division, and launched herself towards his location using her transformed legs. Approaching the vessel, she encountered Naruto Uzumaki and his daughter beside him.
