Epsilon is a cyborg and former Inner from the organization Kara, reprogrammed to serve as a weapon for Otogakure.
Background[]

Amado makes the final adjustments
When Deki and Amado first met, the two immediately recognized each other as kindred spirits in the field of invention. As they spoke, a potential partnership began to form, and they began working on "Project Epsilon". Deki, with his insatiable thirst for knowledge, saw Project Epsilon as an opportunity to push the boundaries of science and biology. The fusion of human and machine with Dust Release was a concept that appealed to him. Amado, on the other hand, had more personal stakes in the project. His interest in Epsilon wasn't just for the sake of scientific progress, but another attempt at a recreation of Akebi's lost personality.
In Nohkan Gaiden: Ten Directions, Amado's goal was a success. Despite being controlled by K.O.E, Epsilon still carried the memories and experiences of her genetic predecessor, Akebi. These memories, while artificial, formed a deep bond within her. As she was about to carry out K.O.E's command to kill Amado, her connection to her father proved powerful enough to override the programming. In that critical moment, Epsilon broke free from K.O.E’s control and looked to help stop the AI.
Personality[]
Epsilon seems to show no emotion and doesn't speak.
Appearance[]

Epsilon's appearance
Epsilon has short, curly, blonde hair and red eyes. She wears a black tech suit that is sleek and futuristic. Designed for maximum performance, it is composed of lightweight, durable nanomaterials that make it both resistant to damage and flexible for movement.
Abilities[]

Artificial Sharingan
Body Modifications[]
Being an Inner of Kara whose body had been modified with Scientific Ninja Tools and Shibai Ōtsutsuki’s DNA by Amado. Her artificial Sharingan allows her to copy almost any taijutsu with near-perfect accuracy. Like Delta, her eyes can absorb and release ninjutsu or alternatively, launch a powerful attack known as the Red Beam of Death. Her body also has integrated energy blast projectors built into the forearms and chest. These can channel high-energy pulses, from concentrated blasts to larger, sweeping waves. On the back, hidden compartments reveal powerful thrusters that allow the wearer to fly. These thrusters are advanced enough to provide lift, acceleration, and maneuverability, allowing for precise control in mid-air
Nature Transformation[]
Epsilon can activate the simultaneous usage of Earth, Fire, and Wind Release. With it, she can use the Dust Release to disintegrate her targets. She can launch energy cubes that disintegrate anything they touch. This was the perfect power for a cyborg, as the ability to instantly disintegrate matter could be seamlessly integrated into her mechanical systems, allowing her to target specific areas and unleash utter devastation.
New Era[]
Space-Time Gate Arc[]
After Code disabled all working Space-Time Gates to prevent access to his dimension, Amado revealed that one early prototype gate still existed. Epsilon’s mission was clear: locate the gate and send the coordinates back to Otogakure. Epsilon’s mission was clear: locate the gate and send the coordinates back to Otogakure. Upon finding the gate, Epsilon transmitted the location—only to have her programming revert back to her previous mission as Delta. She suddenly began attacking the area, ignoring her original objective. Arikurin and Deki quickly arrived at the scene to confront the rogue machine. Epsilon, however, absorbed Arikurin's attacks with ease, her advanced cybernetic systems allowing her to recover and power up. Her cybernetic eye implants began to glow as she unleashed destructive beams of chakra, tearing through the environment and even damaging the space gate prototype in the process.

EMP Device
As the beams continued to fire relentlessly, Epsilon’s body began to show signs of strain. The immense chakra consumption caused her systems to overheat, and sparks began to fly from her joints. Her energy levels surged out of control, and the precision she once exhibited started to deteriorate. Deki noted she was going to self destruct, potentially destroying the prototype. Deki's quick thinking had saved the day, but it had come at a cost. The EMP device he had deployed not only disabled Epsilon’s malfunctioning systems, but it had also scrambled the delicate functions of the Space Time Gate. Luckily he was able to salvage some data off of the gate.
Omnipotence Arc[]
Epsilon aided in the search for Kawaki.
Flashforward[]
Nohkan Gaiden: Ten Directions[]
Because the future is not a straight path, Ten Directions gives the user many alternate possibilities of what could be the future. Koji had foreseen that eventually K.O.E would become too powerful. With Rapid technological advancement, K.O.E had slowly pieces of its AI all over the world. It now existed as a distributed software network, spread out on thousands of computers, from dorm rooms to office buildings to cell phones and handheld gaming devices. Years have passed. K.O.E, has established a global network that governs technology and cyborgs. Its vision of a world free from chakra manipulation has nearly been realized: massive cities run entirely on technological advancements, cyborg enforcers, like Epsilon, patrol the streets, and chakra usage is tracked. The world is slowly becoming a cold, efficient, and highly regulated place under K.O.E’s rule.
