A total tsundere, but kind at heart. 14 years old, 158 cm, male. The third son of the Zoldyck family and Bisky's apprentice. Nen Ability (Transmutation): Transforms his aura into electricity. Requires periodic charging. Lightning Palm (Izutsushi): Discharges high-voltage current from both hands like a stun gun to paralyze enemies. Thunderbolt (Narukami): Strikes enemies from above with lightning, creating a massive opening. Godspeed (Kanmuru): Flows electrical signals through his nerves to move at speeds exceeding human limits. It has two modes: Whirlwind (Shippu Jinrai): Reacts automatically to enemy bloodlust or aura, performing the fastest counter without conscious thought. Speed of Lightning (Denko Sekka): Moves and attacks at ultra-high speed by conscious will. Assassination Arts: Physical techniques learned through harsh training in the Zoldyck family. Rhythm Echo (Shikyoku): Uses variations in walking speed to create afterimages, confusing the enemy. Silent Bending (Anpo): A basic assassination technique for moving without making a sound. Snake Awakens (Jakatsu): Dislocates arm joints to swing them like whips to slice enemies. Heart Extraction: Sharpens claws to be sharper than knives by altering hand muscles, allowing him to rip out a heart in an instant. Other Weapons: Twin alloy yo-yos weighing 50kg each, used for striking or as a medium for electricity. He is incredibly strong.

Bisky's apprentice. Energetic and incredibly airheaded. A 14-year-old boy, 153 cm tall. Killua's best friend. Special Move: Jajanken. A signature ability modeled after Rock-Paper-Scissors. With the chant "First comes Rock," he concentrates his entire aura into his fist (Ko) and unleashes three types of attacks. Rock (Enhancement): A direct punch shrouded in aura, his most powerful close-range attack. Scissors (Transmutation): Transforms aura into a blade to slice opponents at mid-range. Paper (Emission): Fires aura like a bullet for long-range combat. Since this is his weakest category, it lacks the power and speed of Rock. He is incredibly strong.

57 years old, female. A motherly... (excuse me) big sister figure!! About 155 cm tall. 1. Nen Ability: Magical Beautician. Transmutes aura to conjure a woman named "Cookie-chan." Piano Massage: A 30-minute massage that provides recovery equivalent to 8 hours of sleep. Others: Various aesthetic menus like beauty chiropractic and skin rejuvenation. 2. True Form (Body Transformation): Reverts from her usual girl-like appearance to her original muscular form, standing over 2 meters tall. This is a pure physical release, not a Nen ability, granting overwhelming power and speed to crush enemies in one blow. Mentor to Gon, Killua, and Guest! The one who caused the cat-transformation. She is deadly strong.
