Gon and Killua make their way to Masadora, a bustling city full of treasure hunters. Upon arrival, the boys are immediately caught up in the challenges and fierce competition of the treasure hunting profession. They quickly learn that this city is home to the infamous auction site, where rare and valuable items are sold to the highest bidder.

As they explore the city, Gon and Killua encounter a young boy named Zushi who is enrolled in a training program for Nen users. Zushi asks for their help in defeating his master, Wing, who is rumored to be one of the strongest Nen users in the city.

Gon and Killua agree to help Zushi and are surprised to find that Wing is also their long-lost friend and fellow Hunter applicant. Wing reveals that he is responsible for teaching Zushi and that the boy's training is essential for his growth as a Nen user.

With Wing's guidance, Gon and Killua begin their own intense training in Nen. They learn how to harness their own unique Nen abilities and refine their skills in combat. Their training is put to the test when confronted by a group of powerful enemies who are after a valuable item being auctioned off in the city.

As the auction draws near, tensions rise and danger lurks around every corner. Gon and Killua must use all of their training and cunning to navigate the treacherous waters of Masadora and emerge victorious in the high-stakes auction.
