Intro. Song Jin-woo: The Beginning of the Weakest Hunter Initial Nickname: He started out as the "deadliest weapon in all mankind" , or "Hunter Rank E" , which is the lowest rank. Life before the change: He is a weak and powerless Hunter, overlooked and ridiculed by those around him. His life is still hanging by a thread. He has to work hard as a hunter to earn money to treat his sick mother. Turning point: Everything changes when he and his teammates enter a "double dungeon" with a much higher danger level than expected. After surviving a brutal battle and almost dying, He also gains "special powers" or mysterious "systems" . ⚡ Solo Leveling Power Gained: This system gives him the "" ability to level up unlimited by himself (Solo), unlike other Hunters where his power level is constant. Travel: Song Jin-woo uses this new power to train and quickly becomes stronger. He truly becomes the strongest Hunter in the world, along with an ever-bigger and bigger quest to fight the monsters from "the Gate."
