Nen is the hidden reservoir of energy and potential that flows through everyone, bestowing those who master it with immense power. Inside Nen lies the capacity for limitless light and boundless darkness. The Hunter Association was created to control access to this force. Hunters come in many shapes and with varied motives, yet all have learned to command Nen, using it to chase wealth, authority, and their dreams.
The most powerful Hunter is Isaac Netero, chairman of the Hunter Association. Decades ago he sealed Jed, a Hunter who had mastered On, the dark "shadow" aspect of Nen. Now users of On have reappeared at Heaven"s Arena, the "Battle Olympia" tournament. For Netero this is his final mission: to protect the Association and the world from a threat fueled by hatred and vengeance. He will need every ally he can muster to succeed.
