This is a bad habit. I have to stop toying with my prey.
~ Kalluto

Kalluto Zoldyck is a villain from the manga and anime, Hunter x Hunter. He is the youngest child of the Zoldyck family, a family of assassins. He is the younger brother of Killua and Illumi Zoldyck. He also replaces Hisoka as a member of the Phantom Troupe .


Kalluto was born into the Zoldyck family. He was trained in assassination from a young age. He was stated to be jealous of his older brother Alluka. At some point, he was taught Nen.

Kalluto was present when Gon and his friends broke into the Zoldyck's property to rescue Killua. He grew curious when Killua stated that Gon would not be killed. Kalluto went to spy on Gon and his friends. He then asked Gon who they were, and Gon replied "Killua's friends", which confused Kalluto. 

Kalluto helped his brother Illumi, and his great-great grandfather Maha kill the Ten Dons of the mafia. He also helped Illumi switch places with Hisoka, so Hisoka could try to fight Chrollo Lucilfer.

In Greed Island, Kalluto is introduced to Hisoka, who he replaced. He tried to sneak up on Hisoka using zetsu, but was detected. Kalluto used his abilities to track down a nen exorcist to heal Chrollo.

When the Chimera Ant Zazan took over Meteor City, Kalluto joined the Phanton Troupe to defeat the ants. The troupe made a bet that the first one to kill Zazan would become the temporary leader, and Kalluto thought he could succeed. He used his paper dolls to spy on the other members of the troupe. When attacked by a chimera ant, he used his confetti to torture the ant, then grew bored and killed it. He then watched Feitan kill Zazan, and realzed that he was not as powerful as the other troupe members.

Afer Hisoka killed Shalnark and Kortopi, the rest of the Troupe boarded the Black Whale to hunt him down. Illumi, who had recently became a member, came as well. Kalluto and Illumi searched the ship for Hisoka. They were cornered by the Zodiac Miziastom, and Illumi freely admitted that the Phantom Troupe were on the ship.


Kalluto is small, with a feminine appearance. He has long black hair. He wears a Kimono and Japanese sandals.
