Gon and Killua split from the group to train at Heavens Arena for six months, but soon find themselves outmatched by another fighter with an ability called Nen, a required skill for Hunters that Gon and Killua vow to learn quickly.
While preparing to become hunters, Gon and his friends realize they are up against some tough competition and must perform culinary skills to pass their second qualification exam.
Gon, Kurapika, and Leorio are challenged by a group of criminals hired by the Hunter Association and must work together to save the day before time runs out.
The Spiders are closer to unraveling Kurapika's identity, while Kurapika's desire for revenge is rekindled when he discovers that the Spiders are still alive, and during a mad chase through the streets of Yorknew, the Spiders capture Gon and Killua.
Gon, Killua, and Kurapika, finally reunited, are shocked when Kurapika reveals he has made a Nen covenant to strengthen his abilities, at a cost that may be too high for the group to accept.
While Ho-Rang fights off swarms of escaped low-level Foxes, Myung-Ee and Sa-Euh form an uneasy alliance to go after Yu-Da, who has sided with the eerie Ha-Euh instead of either the Rabbits or the Foxes. Plus, Myung-Ee regains some of her memories and what she remembers will affect everyone involved.
Hee-Ju fails at hostage negotiations with Ha-Eun, Yumei, and Mi-Woo, which leads to heartbreak for Myung-Ee as the leader of the Moon Foxes makes a trip to the Blue Planet to inflict punishment on those who try to stop him.
Myng-Ee confronts the student council about Yu-Da, but soon finds herself transported to a strange place where she faces an attack from an unexpected assailant and discovers an unexpected friend.
