One Piece "3D2Y": Overcome Ace's Death! Luffy's Vow to his Friends

In this two-year gap tale, Luffy continues his gruelling training in Rusukaina, aiming to sharpen his skills for the perilous New World. His focus is interrupted when Boa Hancock’s sisters, Marigold and Sandersonia, are taken hostage by Byrnndi World, a ruthless pirate who once sat behind bars on Level 6 of Impel Down. He escaped during Luffy’s bid to rescue Ace and now uses Hancock’s Shichibukai status as leverage to draw the World Government’s attention. Luffy and Hancock join forces to confront the kidnapper, racing to protect the sisters and thwart a bold plan that threatens their crew’s safety.

Released in 2014, this One Piece feature was directed by Naoyuki Ito and draws its story from Eiichiro Oda's beloved manga, continuing the franchise's adventurous style while fitting into the pre Sabody time frame.

The film shores up Luffy's role as a steadfast ally within the crew driven by loyalty and friendship. It also spotlights Hancock as a capable partner rather than a distant ally, enriching the series dynamic and reinforcing the series' playful yet high stakes tone.

Critics noted the film packs brisk action with humor while threading themes of duty, trust, and teamwork. The story foregrounds Luffy's growth under pressure and the cost of power, while dramatizing the tension between individual freedom and responsibility within a tight pre Sabody arc.

This anime feature is drawn from Eiichiro Oda's manga and directed by Naoyuki Ito. It uses the familiar One Piece voice cast led by Mayumi Tanaka as Luffy, with Kazuya Nakai, Akemi Okamura and Arata Furuta providing key roles.
