Dragon Ball Super Episode 71
The Death Of Goku! The Guaranteed Assassination Mission
Goku begins acting strangely. He admits to Gohan and Goten that he thinks someone wants to kill him. Meanwhile, in Universe Six, Hit carries out an assassination mission by killing a crime boss. His next target is revealed to be Goku. Goku senses Hit coming and flies to a remote area so that their fight would not put anyone else in danger. Hit arrives to kill Goku. Goku charges at Hit, but he cannot hit him. Hit seemingly kills Goku with a single blow to the chest and disappears just before Piccolo, Gohan, and Goten arrive and find Goku’s body.
