One Piece 3D2Y: Overcoming Aces Death Luffy's Pledge

Haunted by the tragic loss at Marineford, Luffy continues his two-year training session under Rayleigh's tough tutelage.

Determined to save them, Luffy teams with Hancock for a bold rescue operation that won't just test his new powers—it'll test his will to get stronger for the crew that awaits his return.
