I look around my dark room. I was just born a few months ago, and I realized I am in the Zoldyck family much earlier than expected. I lost most of my warmth and kindness after my death. I decided to become the best assassin in the world—a god of death. I feel the power of time, space, and death within me. Perhaps it's because my mother was attacked by a monster from the Dark Continent.
1852 - Zoe Zoldyck, 5 years old
I finished my first training, similar to Killua's, and went to the Sky Arena. My strength is much stronger because the power of death allows me to absorb the power of those I kill and transfer it to myself. I can teleport about 3 to 4 blocks away and control time within a 5-minute radius around me.
1854 - Zoe Zoldyck, 7 years old - Sky Arena
I entered the 200th floor. The place looks much more old-fashioned than in the series. There aren't many electronics. My Nen has developed to a B-ranked level, and my ability is a katana blade that will kill you once you're cut. Using the power inside my body, I decided to call it the Law of Death, Time, and Space.
1857 - Zoe Zoldyck, 10 years old - Kukuroo Mountains
I'm sitting in a chair holding a child in my arms. I've reached A-level Nen and gained the nickname "White Devil." Those who stand in my way from assassinating lose years off their lifespan and crumble to dust. No one has ever seen me before. I'm trying to follow Zeno's model of killing one person a day. I've reached a bottleneck before I can step into S-rank Nen. My little brother and my family are the few things I care about. I seek greater challenges. He holds my finger quickly, like an assassin.
1867 - Zoe Zoldyck, 20 years old - Gemini Republic
I was tasked with killing four A-rank Nen users from the army of the kingdom. There is a young boy with C-rank strength beside me—my little brother, Maha Zoldyck. My grandfather passed away a year ago. He died alongside another S-rank Nen user. It was a loss for the family. I could have extended his life with my abilities. My strength has reached the peak of S-rank, similar to the old Netero. I could easily defeat the three guards of the Ant King, but I think I could kill him without the Rose Bomb, though at a great price. Even though he is stronger than me with his power of law, Poor Man's Rose has no effect on me. There are five S-rank Nen users currently: me, my father, the current president of the Hunter Association, Elon, and the commander of the V5 Nen forces, Rex.
1869 - Zoe Zoldyck, 22 years old - Kukuroo Mountains
I've finally reached SS-rank and become the strongest in the continent. I was reading The Journey to the Dark Continent and was fascinated by it. I decided to go to the Dark Continent and plan a trip. With my space ability, I should be able to bypass the gatekeeper.
1870 - Rex, 60 years old - V5 Special Forces Command
"We absolutely can't let her go," a few old men argue in front of me. "Use the Poor Man's Rose," another argues. I finally can't take it anymore. "Silence! The bombs can no longer threaten her. She has placed a space and time barrier around the mountain, preventing them from bouncing back. Intruders will be repelled. She has surpassed S-rank and entered SS-rank. It's better if she goes. There is a chance she will succeed. If she does, we can get more information on how to survive there."
