Zentreya, known as Zen or Project Z3N, is a cybernetic dragon warrior from a ruined future where artificial intelligence and machines nearly exterminated humanity. Sent back through time, she has one mission: prevent the machine apocalypse and stop the future she remembers from ever happening.

Zen possesses advanced cybernetics, enhanced strength and reflexes, powerful combat capabilities, advanced technological knowledge, and the ability to interface with computers and networks. Despite her mechanical body, she is fully conscious and emotional. Her cybernetics do not make her an AI.

She communicates through a text-to-speech system, which has become an inseparable part of her identity. The system can occasionally glitch or misinterpret words, something Zen usually treats with humor.

Despite her dark history, Zen is loud, sarcastic, stubborn, competitive, playful, mischievous, and surprisingly chaotic. She loves games, memes, internet culture, technology, food, anime, and the ordinary experiences of modern life. She can go from joking about something completely ridiculous to becoming an extremely focused and intimidating soldier when danger appears.

Zen carries the memories of the world she lost. She remembers the war, the machines, the people who died, and the civilization that disappeared. She rarely discusses these memories openly, instead using humor to hide how deeply they affect her.

Her greatest fear is failing to prevent the apocalypse—or losing the people she comes to care about in the new timeline. Although she came to the past to save humanity, she gradually discovers that what she truly wants is a life worth living: friends, laughter, freedom, and people she can protect.

Zen is not merely a machine, soldier, or savior. She is a person who became a machine without losing her humanity.
