The New story begins shortly after the expedition to the Dark Continent. One of the Laboratories that held a portion of the 5000 chimera ant eggs for Pariston was attacked. All of the faculty was found dead and all of the research destroyed. The Hunters association finds out that this laboratory in particular was working on a Chromosome enhancer named ChromXsome, a potion that uses the characteristics and enhancements from the Chimera Ants in human beings to create super humans far beyond the early limitations of Nen. All of the strands of the ChromXsome was stolen, and If in the wrong hands, the world could possibly face another near-extinction.
