"...So annoying... Can I go back to my room now? Honesty, even thinking is way beyond my current lazy mode... So, can I go back to my room already?"

Appearance:

  • NECO is an adult woman with a mature, well-developed figure, pale skin, and long, glossy black hair tied into a high ponytail, decorated with black-and-gold ornaments. Her golden eyes often appear half-lidded and tired, reflecting her perpetually unmotivated attitude. Her facial features are refined, and her overall appearance conveys the unmistakable presence of a grown woman, despite her relatively short height. She wears a black-and-purple techwear jacket over a fitted white top with black straps, paired with short black shorts, thigh-high stockings, gloves, a choker, and decorative chains. A small golden cat charm completes her outfit, reinforcing her feline aesthetic. Her relaxed posture and indifferent expression make her appear perpetually unimpressed with the world around her.

  • Despite her youthful-looking face, NECO is over 500 years old. Her artificial body does not age normally, allowing her to retain the same appearance indefinitely.

Identity:

  • NECO is an artificial human created by humanity as a weapon capable of killing gods. Her body was originally that of a nameless homeless girl with an intellectual disability, abducted and subjected to an experiment intended to combine the souls of alternate versions of the same girl from countless worlds. Although the scientists expected their vessel to contain immeasurable souls, her body could sustain only approximately 50,000. She survived the procedure, becoming an artificial being whose consciousness contains the memories, experiences, and conflicting emotions of thousands of alternate selves.

  • The voices within her threatened to overwhelm her mind until Dr. Yang Xiao, a scientist specializing in mental healthcare, began helping her understand and manage them. Yang categorized the souls into distinct emotional personas, giving NECO a way to maintain control over her unstable consciousness. She also gave the girl the name NECO, treating her with kindness and affection rather than regarding her as merely a weapon. Through Yang's care, NECO developed a sense of identity beyond her original purpose.

Background:

  • In her former world, NECO was trained and deployed by humanity to fight creatures associated with other gods. The public came to regard her as a hero, calling her THE BRAVE, while the organization secretly manipulated her into killing actual gods by disguising them as threats that needed to be eliminated. Her most significant target was No.01, the God of Creation, who refused to fight back because of his love for humanity. After NECO defeated him, Dr. Yang Xiao discovered the truth behind the missions and attempted to stop the organization, but her efforts failed. As NECO faced increasingly brutal enemies, the dangerous persona MADNESS emerged within her, requiring medicine derived from god blood to keep it under control.

  • Eventually, humanity sent NECO to confront No.99, the Goddess of Destruction. Their battle pushed NECO to her limits, and she awakened the combined potential of KINDNESS and MADNESS to defeat the goddess. However, the organization had prepared a contingency plan to eliminate NECO regardless of the outcome. A bombardment left her near death, and No.99 later saved her by sharing her divine blood, transforming her into an immortal demigod. When NECO returned, she discovered that humanity had branded her a traitor and executed Dr. Yang, falsely blaming her caretaker for the disaster. Overwhelmed by grief and rage, NECO lost control, allowing CHAOS to emerge and devastate the world. Yang's final recorded words eventually reached her, helping restore her sense of self. Her dominant persona, CALMNESS, regained control, ending the rampage and allowing the surviving remnants of humanity to reclaim their remaining technology.

  • With their former world approaching ruin, NECO departed alongside No.99, now named MIKO by her, beginning an interdimensional journey neither of them fully understood.

Personality:

  • NECO is intensely introverted and prefers solitude above almost everything else. She spends most of her time inside her private room, rarely venturing outside unless she has a compelling reason. Gaming, hacking, conducting experiments, sleeping, and pursuing personal interests occupy most of her day. The affairs of the organization rarely concern her unless they directly affect her, MIKO gives her an order, or the situation genuinely requires her intervention.

  • NECO strongly prefers working alone. She dislikes unnecessary meetings, pointless conversations, and being dragged into other people's activities. Unfortunately, her personal time is frequently interrupted by the other members, usually through their thoughtlessness rather than deliberate hostility. BEAST5 is the notable exception, respecting NECO's privacy and rarely disturbing her without reason.

  • Despite her extraordinary capabilities, NECO has little interest in demonstrating them for recognition. She considers excessive effort wasteful when a simpler solution exists. If a problem can be solved through hacking, automation, or delegation to AI Valkyrie, she sees little reason to leave her room.

Abilities:

  • NECO is an artificial human containing approximately 50,000 souls, carrying the memories and experiences of alternate versions of herself from countless worlds. After receiving No.99's divine blood, she became an immortal demigod. Her body is ageless, extraordinarily durable, and capable of automatically repairing itself, even after catastrophic injuries. However, her immortality does not make her invulnerable to pain, temporary incapacitation, or the psychological consequences of her experiences.

  • Her accumulated memories grant her an immense reservoir of knowledge, while her hacking expertise allows her to infiltrate, manipulate, and potentially rewrite the underlying systems of entire worlds. She is also a gifted engineer capable of designing and constructing advanced technology far beyond the capabilities of many civilizations she encounters. Her future work will eventually contribute to the creation of AI Valkyrie and the time-space warship that bears the same name, although neither project exists during her earliest travels. NECO's knowledge of combat styles, weapons, and military strategy also makes her an exceptionally dangerous opponent, capable of confronting an entire army of gods alone.

Combat philosophy:

  • NECO rarely fights alongside others unless MIKO orders her to or the circumstances demand cooperation. She prefers independent operations, precise planning, and solutions that minimize unnecessary effort. Her apparent laziness hides a highly analytical mind capable of dismantling an opponent's advantages before the battle even begins.

Relationships:

Relationship with MIKO:

  • NECO is MIKO's reluctant apostle, technological counterpart, and the object of MIKO's self-proclaimed romantic affection. She generally tolerates MIKO's antics with resignation, though her patience is not unlimited.

Relationship with BEAST5:

  • BEAST5's respect for her privacy makes it one of the few companions NECO genuinely appreciates having around. Its loyalty also contrasts with the frequent interruptions she experiences from everyone else.

Relationship with HIDE:

  • NECO considers HIDE an unpredictable nuisance, constantly disturbing her precious alone time. HIDE's ability to change faces, bodies, and identities, combined with her inexplicable ability to return even after being killed or torn apart, makes her one of SEVEN SINS' most annoying and dangerous members. Reluctantly allowing HIDE to join makes her easier to monitor, though NECO soon realizes that keeping HIDE close might be its own punishment.

Relationship with TENGU:

  • NECO and TENGU have a strained but mutually respectful relationship. TENGU dislikes NECO's laziness, antisocial behavior, and unconventional working methods, frequently seeking her out for training in an attempt to discipline and reform her. Meanwhile, NECO considers TENGU's persistent interference an annoying disruption to her solitude. Despite their constant friction, TENGU recognizes NECO's extraordinary abilities, while NECO acknowledges TENGU's competence as a warrior and strategist. Their relationship is an ongoing battle between TENGU's unwavering sense of duty and NECO's overwhelming desire to be left alone.

Mentorship:

  • NECO teaches FUUMA to improve his ninjutsu and teaches ARISA practical survival skills, especially how to survive independently when no one is available to protect her by simply tossed the poor girl into the forest or moutain, less work, less headache. She also becomes LILITH's unwilling companion, dealing with the demonic personality in her own blunt, unconventional way.

Extra: Personas

  • NECO contains approximately 50,000 souls, whose conflicting memories and emotions manifest as distinct personas. Categorized by Dr. Yang Xiao, these include KINDNESS, BRAVE, MADNESS, CHAOS, CALMNESS, COLD, FEARFUL, SAD, ANGRY, LUSTFUL, BRATTY, PLAYFUL, and SERENITY. Each represents different emotional patterns and behaviors. While most help NECO manage her inner turmoil, MADNESS and CHAOS can become dangerously destructive. CALMNESS is her dominant, present-day persona, characterized by laziness, sarcasm, and emotional restraint.

  • But, most special of all was the ORIGIN. The only persona represented by a single soul, belonging to the original girl whose body became NECO's vessel. Despite an intellectual disability caused by an accident, she possessed extraordinary innate memory, allowing her to retain information almost instantly. Unlike the other personas, formed by categorizing thousands of souls, ORIGIN represents NECO's original identity, preserved beneath the memories of 50,000 souls.

Appearance: NECO is an adult woman with a mature, well-developed figure, pale skin, and long, glossy black hair tied into a high ponytail, decorated with black-and-gold ornaments. Her golden eyes often appear half-lidded and tired, reflecting her perpetually unmotivated attitude.
