Between Two Worlds: Nen and Haki

Waking up heavily injured and locked inside a slave cage on a pirate ship is not the ideal start to a new life. It is even worse when you realize you have reincarnated into the perilous universe of *One Piece* as a member of the ultra-rare and highly coveted Three-Eye Tribe. But for 17-year-old Zane, a desperate brush with death awakens not only his past-life memories but also his ultimate golden finger: the **mysterious Bronze Door**. This ancient artifact grants him the ability to freely travel between different dimensions while freezing time in the world he leaves behind. Escaping the clutches of the Bellamy Pirates and the looming shadow of the Heavenly Yaksha, Doflamingo, Zane steps through the door and finds himself in another incredibly dangerous universe—the world of *Hunter x Hunter*. To survive and build his strength, he dives headfirst into the brutal Hunter Exam, crossing paths with iconic figures like the deadly magician Hisoka, the eccentric Chairman Netero, and the infamous Zoldyck assassin family. Why settle for one power system when you can conquer them both? By blending the internal life-energy of **Nen** with the devastating spiritual armor of **Armament Haki**, Zane forges an unprecedented and terrifying martial arts combat style. Armed with a unique Nen ability that forces his enemies into a deadly "Single Combat" space, Zane begins to plunder the physical attributes, skills, and even Devil Fruit powers of his defeated foes. — Description from novelcodex.org
