Assassin is the 466th chapter of Hiro Mashima's Fairy Tail. While Zeref continues his advance towards Magnolia after his battle against his younger brother, Natsu mulls over the information he obtained from the Black Mage. Meanwhile, Fiore's forces prepare to clash against the Alvarez Empire on the southern, northern and eastern fronts. Elsewhere, Marin manages to infiltrate Fairy Tail's prison, but, instead of freeing Brandish, he proceeds to attempt to assassinate her for all the wrongs she has done him in the past.
