Nen: the hidden source of energy and potential that runs through everyone, and gives those that master it a source of great power. Inside Nen is the potential for limitless light and limitless darkness. The Hunter Association has arisen to control access to it. Hunters come in many shapes and forms, and with many different appetites - but all of them have learned to master Nen, and use it to chase wealth, power, and their dreams. The greatest and most powerful Hunter is Isaac Netero, chairman of the Hunter Association. Decades ago he sealed away Jed, a Hunter who had mastered the use of On, the dark "shadow" of Nen. Now On users have reappeared at the Heaven's Arena "Battle Olympia" tournament. For Netero, this is the last mission: to protect the Association and the world from a threat driven by hatred and the thirst for revenge. And he's going to need all the help he can get in order to succeed.

In response to the worsening crime rate, Japan creates Tokyo Butei High, an elite academy where "Butei" or armed detectives hone their deadly skills in hopes of becoming mercenary-like agents of justice. One particular Butei is Kinji Tooyama, an anti-social and curt sophomore dropout who was once a student of the combat-centric Assault Division. Kinji now lives a life of leisure studying logistics in order to cover up his powerful but embarrassing special ability. However, his peaceful days soon come to an end when he becomes the target of the infamous "Butei Killer," and runs into an emotional hurricane and outspoken prodigy of the highest rank, Aria Holmes Kanzaki, who saves Kinji's life and demands that he become her partner after seeing what he is truly capable of.

For over one hundred years, a special quest has been waiting for a wizard skilled enough to complete it. On the northern continent of Guiltina, there are five immensely powerful Dragon Gods who possess great destructive force that can only be quelled by sealing them away. Natsu Dragneel and his friends from the Fairy Tail guild—Lucy Heartfilia, Gray Fullbuster, Erza Scarlet, Wendy Marvell, and the exceeds Happy and Charlés—consider this the perfect challenge to take on. The Fairy Tail mages are not the only ones searching for the Dragon Gods. Diabolos, a guild exclusive for "Dragon Eaters," seeks to enhance their Dragon Slayer magic by devouring the dragons. Meanwhile, Fairy Tail's newest addition, Touka, appears to be hiding something sinister from her new companions—and her secrets may bring disaster to the guild while its strongest wizards are away.
