Here’s something the anime industry figured out a while back that most fans still haven’t quite registered: the women of One Piece have been carrying the franchise on their backs for years, and somebody finally decided to monetise that properly.
During the AnimeJapan 2026 panel, One Piece Heroines dropped its first trailer—and it’s exactly the kind of side project that makes you tip your cap to whoever in Shueisha’s meetings said, “Finally.” This isn’t a sequel. This isn’t a prequel. This is a deliberate, carefully assembled play at an audience that’s been asking for this specific content since the Bush administration for nearly two decades.
What We Know So Far
The project hits Fuji TV on as a special one-time anime, kicking off with an episode simply titled “NAMI.” That simplicity is telling. They’ve identified the draw, pointed the camera directly at it, and built around that single focus.
Director Haruka Kamatani, scriptwriter Momoka Toyoda, and character designer Takashi Kojima have the unenviable task of translating light novel illustrations into something that doesn’t feel like a compromise—and from what the trailer shows, they’ve pulled it off without the usual wobble.
The Voice Casting Tells Its Own Story
- Maaya Sakamoto — known for Shinobu Oshino in Monogatari and Echidna in Re:Zero — takes on Miucha.
- Takehito Koyasu — the voice of Dio Brando in JoJo’s Bizarre Adventure and Zeke Yeager in Attack on Titan — steps into Lubun.
That’s not accidental casting. That’s two established heavyweights brought in to signal this isn’t a throwaway curiosity. It’s a statement.
Why the Structure Works
Written by Jun Esaka with artwork by Sayaka Suwa, these light novels have been serialising in One Piece Magazine since , with the first physical volume landing in under Shueisha’s banner.
The format—an anthology of self-contained stories focusing on the female characters—sidesteps the trap that often ensnares spin-offs.
You can drop in for:
- Nami at a fashion show
- Robin deciphering ancient tablets alongside Sabo and Koala
- Vivi dealing with a mysterious love letter
- Perona battling Zoro and Mihawk over the last bottle of wine at Kuraigana Castle
You’re in immediately. No homework required.
The Bigger Picture
The anime industry has recognised that character-driven, lower-commitment content serves a market that wants engagement without the mortgage application of following a 1,000-episode main series. One Piece Heroines is precision-targeted at exactly that.
So the question isn’t really whether this will find its audience—the question is why it took this long what took them so long, and what other characters have been sitting on similar potential that studios haven’t bothered to unlock yet.
Perona got an outing here. But who’s next? Reiju? Big Mom herself? Sometimes the most obvious plays are the ones that slip right past everyone.
