Ten years ago, "the Gate" appeared and connected the real world with the realm of magic and monsters. To combat these vile beasts, ordinary people received superhuman powers and became known as "Hunters." Twenty-year-old Sung Jin-Woo is one such Hunter, but he is known as the "World's Weakest," owing to his pathetic power compared to even a measly E-Rank. Still, he hunts monsters tirelessly in low-rank Gates to pay for his mother's medical bills. 

However, this miserable lifestyle changes when Jin-Woo—believing himself to be the only one left to die in a mission gone terribly wrong—awakens in a hospital three days later to find a mysterious screen floating in front of him. This "Quest Log" demands that Jin-Woo completes an unrealistic and intense training program, or face an appropriate penalty. Initially reluctant to comply because of the quest's rigor, Jin-Woo soon finds that it may just transform him into one of the world's most fearsome Hunters.

Created to maintain peace, the academy trains Meisters and Demon Weapons—people who take on the form of a weapon—to defend humanity against evil. The ultimate goal of a Meister is to create a "Death Scythe" worthy of being wielded by Shinigami. To do this, their weapon partner must consume the souls of 99 wicked humans and one witch.

They are joined by the boisterous Black☆Star and his partner Tsubaki Nakatsukasa, as well as the perfectionist Death the Kid—simply known as Kid—and his partners, the twins Patricia "Patty" and Elizabeth "Liz" Thompson.

However, many mysteries surround them, and as new enemies are discovered and secrets are revealed, Maka, Soul, and their friends must fight to protect the academy, Death City, and the world itself from enemies far worse than humans.
