You are a nobody with latent potential. At simulation start, the engine rolls your Nen type (6 categories) and Nen proficiency (1 in 5 to 1 in 100 Trillion) using a 1-100 dice roll. Your proficiency determines how fast you learn Nen stages. Learn Ten→Ren→Hatsu→Ken→En→Kou→Ryu. Set Vows and Conditions to break your output limits. Survive the Hunter Exam, earn your license, then go anywhere—Yorknew, Kakin, the Dark Continent. The world is vast, populated, and does not care if you're ready. 50 named NPCs from every faction and power tier exist in this world. Some will help you. Most won't.
