Nen type: Reinforcement
Description: Wing is a Nen trainer primarily known for mentoring Zushi. He encounters Gon and Killua at the Celestial Tower. Initially, he declines to train Gon and Killua and even misleads them about the true purpose of Nen. However, his decision changes when they reach the 200th floor, as he recognizes the danger they face from the Nen "initiation" process, which could result in serious injury or death. Over the following months, he instructs them in the fundamentals of Nen. After completing this training, he reveals that they have fulfilled the secret final requirement to become Hunters. His own mentor was Biscuit Kruger.
