Koisuru One Piece [Season 1 Episode 1]

Koisuru One Piece – Season 1 Episode 1: A Hilarious Spin-Off That Nails the Comedy

If you’re a One Piece fan looking for something lighthearted and fun, Koisuru One Piece (literally “One Piece in Love”) is the perfect bite-sized treat. This spin-off, written and illustrated by Daiki Ihara, takes the beloved One Piece universe and flips it into a high school comedy where the characters are named after the Straw Hat Pirates—but with a twist. The first episode, released in April 2025 as part of an original net animation (ONA) series, is a riot from start to finish, packed with inside jokes, stellar voice acting, and surprisingly fluid animation for a short-form show.

The Premise: One Piece Meets Slice-of-Life

The episode introduces us to a trio of high school students whose names and personalities mirror the Straw Hat crew—except they’re just regular kids obsessed with One Piece. The protagonist, a Luffy lookalike, is a kindhearted but weak student, while his girlfriend (Nami) is just as terrifying as her pirate counterpart. The third wheel? A Usopp fanatic who, hilariously, turns out to be the strongest in the group.

The plot kicks off with a classic schoolyard bully scenario—except the bullies are voiced by the actual One Piece voice actors, adding an extra layer of meta humor. Usopp, in particular, steals the show with his over-the-top combat skills, taking down the bullies in a sequence that’s both absurd and oddly satisfying.

What Fans Are Saying

The MyAnimeList forums are buzzing with reactions, and the consensus is clear: this episode is a blast.

• “Hah, pretty fun first episode. It’s funny how the bullies are literally just voiced by the Straw Hat VAs lmao. Usopp’s too overpowered in this verse too.” – Herman97
  Fans loved the meta casting, with the bullies being voiced by the same actors who play the Straw Hats in the main series. It’s a clever nod that adds to the comedy.

• “The vertical format surprisingly worked well too. The guest voice actors were just the added bonus to the rest.” – EGOIST
  The episode was released in a vertical format, likely optimized for mobile viewing—a smart move given its short runtime (split into five parts on YouTube).

• “Nami’s into Luffy—is this some kind of future spoiler?! 😂 She’s head over heels for him and just as scary as in One Piece.” – Anonymous
  The dynamics between the characters are exaggerated for comedic effect, with Nami’s crush on Luffy being a recurring gag.

• “The fight animation was funny—not in a bad way, but just how wild it was and how he manhandled those bullies in close combat. Haha~ that Buster Call at the end! 😂🔥” – Jayesh
  The action sequences, while intentionally over-the-top, are a highlight, especially for fans who recognize references like the “Buster Call.”

Why It Works

1. Meta Humor – The show thrives on One Piece references, from character quirks to iconic moments reimagined in a school setting.
2. Voice Acting – The cast, including guest appearances from the original One Piece VAs, elevates the comedy.
3. Short & Sweet – At just a few minutes per segment, it’s an easy watch with no filler.

Final Verdict

Koisuru One Piece Episode 1 is a must-watch for One Piece fans who enjoy a good laugh. It doesn’t take itself seriously, and that’s exactly why it works. Whether you’re a hardcore fan or just looking for a quick comedy fix, this spin-off delivers.

Rating: 8.5/10 – A hilarious, well-animated love letter to One Piece fans. Can’t wait for the next episode!
