Nano Ascension - inspired by "Nano Machine" manhwa

Invisible, powerless, and bullied—this is the life of a seventeen-year-old in Seoul. Until a mysterious cyber-metal fragment changes everything. Integrated with a Nano Machine AI, they gain abilities beyond human limits. Strength, speed, intelligence—nothing is impossible. “Nano Ascension” is a story of transformation, power, and choice. Will they protect, dominate, or transcend humanity itself? Note; I am still not familiar with character creation in this site, so bear with me. Hopefully you enjoy this scenario. I am open to all your suggestions to improve this. Thank you.
