Memoroar – For over two decades, One Piece has mastered the art of the epic. We’ve followed Monkey D. Luffy and his crew through earth-shattering battles, toppling tyrants and challenging gods. We cheer for the grand gestures and the world-changing punches. But what about the people on the ground? The ones who have to sweep up the rubble after a city-block-leveling fight? The 25th-anniversary special, One Piece Fan Letter, shifts the camera away from the demigods on center stage and points it directly at the audience, delivering what is not just a side story, but a profound and essential piece of the One Piece puzzle.
It’s no exaggeration to call this OVA a triumph. Upon its release.
Fan Letter became the highest-rated anime special of all time on sites like MyAnimeList, a testament to how deeply it resonated with viewers. Based on a collection of short stories by Tomohito Osaki, the special is set during the Straw Hats’ reunion on Sabaody Archipelago, a pivotal moment of new beginnings. Instead of focusing on the crew, it tells the parallel stories of the people whose lives are orbits around the chaos of the Straw Hats’ journey: two rank-and-file Marine brothers and a young girl determined to give her idol, Nami, a fan letter.
What follows is a 24-minute masterclass in perspective that every fan of the series should consider required viewing.
The Horror and Humanity of the Common Man

The special’s most powerful achievement is reframing the grand spectacle of One Piece as a terrifying, ground-level experience. This is most brilliantly realized through the story of the two Marine brothers. We witness the Battle of Marineford not as a clash of legends, but as a horrifying natural disaster. Under the stunning direction of Megumi Ishitani, whose work on the main series’ openings has been widely praised, the world-shaking powers of the series’ titans are shown for what they are to a normal person: pure terror.
A laser beam from an Admiral isn’t a cool attack; it’s a random flash of light that could vaporize you instantly. An earthquake from a Yonko isn’t a display of power; it’s the ground beneath you ceasing to exist. The animation focuses on the desperate, frantic movements of survival—a leg being wrenched from rubble, a panicked scramble away from an unseen explosion. For the first time, the “fodder” Marines, often used as comic relief, are given a voice and a soul. Their motivation isn’t “Absolute Justice,” but the simple, human desire to protect their family in the middle of an apocalypse. It’s a sobering and necessary reminder that in a world of monsters, just being a regular person is the most dangerous thing of all.
The Revolutionary Power of a Fan

Contrasting the terror of the Marines’ story is the boundless hope of the special’s other protagonist: an unnamed girl whose simple goal is to hand-deliver a fan letter to Nami. Her story is a beautiful meta-commentary on the nature of fandom itself. She idolizes Nami not for a Devil Fruit power, but for her intelligence, grit, and determination—qualities that feel attainable.
This admiration isn’t passive. When the Straw Hats are in trouble, the girl doesn’t just watch. Inspired by her hero, she takes a page from Nami’s own playbook, using her wits to create a clever diversion that helps them escape. In that moment, she stops being a spectator and becomes a part of the story. The episode’s climax, where she floats in the water, letter successfully delivered, watching the Thousand Sunny sail away with tears of pure joy, is one of the most emotionally cathartic moments in recent anime. It perfectly captures the feeling of wanting your favorite characters to succeed and continue their journey, because their adventure is also yours.
The Verdict: An Essential Love Letter
One Piece Fan Letter succeeds because it understands the heart of the main series better than almost any other supplemental material. It functions as the ultimate animated version of Eiichiro Oda’s famous manga cover stories, which periodically check in on the side characters and locations the Straw Hats have impacted. It reminds us that the world of
One Piece is alive, breathing, and watching, just like we are.
By showing us both the terror and the inspiration the Straw Hats leave in their wake, the special enriches the entire saga. It gives weight and meaning to their fight for freedom by showing us the very people they are fighting for. The final shot, where the crew seems to look out at the viewer, is a direct acknowledgment of this bond. It’s a love letter to the fans, to the world, and to the very idea that even from the sidelines, we can all be a part of the adventure. It is, without a doubt, a masterpiece.
