Hook
One Piece does not ask you to judge a single episode like a movie. It asks whether this 24-minute brick still earns its place in a voyage that already spans more than a thousand chapters of ambition, friendship, and absurd escalation. “Advance, Law! The Kindhearted Man’s Final Fight!” is one of those bricks inside Dressrosa — the Wikipedia/TV season that covers overall episodes 629–746.
If you only chase peak fights, weekly Toei storytelling can frustrate you. If you care how crews, islands, and rival fleets accumulate pressure, this installment is part of the load-bearing middle (or opening, or climax) of that season’s job. The question this page answers is simple: should a sequential viewer watch “Advance, Law! The Kindhearted Man’s Final Fight!,” and what does it actually change?
Kagex scores below are for this episode only — not a grade for the entire Dressrosa saga and not a grade for the manga chapter it adapts.

Should You Watch It?
Yes if you are watching One Piece in order through Dressrosa. Skipping “Advance, Law! The Kindhearted Man’s Final Fight!” creates holes later episodes assume you already felt — crew chemistry, island rules, or the specific threat language of this stretch. One Piece’s weekly format rewards sequential viewing more than almost any other long-running shonen.
Beginner-friendly as a random start? No. Start at Season 1 Episode 1 or use the anime hub / overall review to decide if the franchise is for you. Dropping into overall #706 cold will feel like arriving mid-conversation on a ship that already chose its captain.
Who enjoys this kind of episode? Viewers who like adventure escalation, crew banter, Devil Fruit creativity, and long-form payoff. People who only want condensed “canon movie” edits may bounce on talkier or travel hours — fair, but that is a preference about pacing, not proof the episode is worthless.
Bottom line: sequential fans should watch “Advance, Law! The Kindhearted Man’s Final Fight!.” Fight-only skim culture will underrate quieter setup inside Dressrosa. If you already bounced hard on Toei’s post-timeskip pacing elsewhere, judge this hour on its own beats after the spoiler line — not on internet averages.

Story Recap
Recap below is grounded in publicly listed episode synopsis text for overall #706. Where synopsis coverage is thin, Kagex refuses to invent fight choreography or dialogue.
Ordinary Voyage
Inside the Birdcage surrounding the ghost town on Minion Island, the Barrels Pirates are running while being attacked by crewmates controlled by Doflamingo’s strings. A shocked platoon of Marines stand outside and report what is going on while trying to break through the Birdcage, to no avail. Meanwhile, a boy named Dory has ended up outside the Birdcage, and three of his trapped crewmates beg him to help them. However, Dory runs away. Meanwhile, two pirates are shot dead by the Donquixote Pirates, and Barrels hears it from inside his headquarters. Kagex keeps the recap tied to what this aired installment actually moves — crew status, island pressure, or the next voyage problem. Watching “Advance, Law! The Kindhearted Man’s Final Fight!” in order matters because Dressrosa, Doflamingo, Colosseum context from earlier Dressrosa episodes is assumed, not re-explained from zero.
Unexpected Incident
He curses Dory for abandoning them as he prepares for battle at the entrance. Suddenly, Doflamingo cuts apart the door and proceeds to slash Barrels, causing him to collapse. An angry Barrels asks Doflamingo if his crew stole the Ope Ope no Mi, but Doflamingo replies that if they did he would not have to go to this trouble. Doflamingo denounces Barrels for letting the Ope Ope no Mi get stolen as he pulls out his gun and shoots Barrels twice.

Story Analysis
“Advance, Law! The Kindhearted Man’s Final Fight!” works or fails based on how clearly it advances Dressrosa. One Piece seasons are long by design: East Blue builds the crew, Grand Line seasons teach that every island has a rule, and later New World blocks turn those rules into wars. Episode 78 of Season 17 is one turn of that machine.
Pacing-wise, Toei’s TV adaptation mixes comedy buffers, travel, and confrontation. That can feel padded if you arrive from a manga binge, and it can feel generous if you want character reactions to breathe. Kagex does not pretend every minute is peak sakuga. We ask whether the hour changes stakes, relationships, or information. In Dressrosa, the recurring keywords — Dressrosa Doflamingo Colosseum — tell you what kind of change to look for.
Emotionally, One Piece sells sincerity harder than irony. Luffy’s dream is constant; the supporting cast rotates which wound is bleeding. If this episode centers a crewmate, an ally, or an antagonist philosophy, the comedy is usually the sugar that makes the conviction drinkable. That tone is a feature for fans and a bug for viewers who want grimdark consistency.
Structurally, overall #706 sits between “The Moment of Resolution! Corazon’s Farewell Smile!” and “To Be Free! Law’s Injection Shot Blasts!”. Read it as a chain link. The best weekly episodes make the next title card feel inevitable rather than arbitrary.
Compared with shorter modern cours, One Piece asks for patience. The trade is cumulative awe: when Dressrosa finally detonates, earlier “small” hours become receipts. “Advance, Law! The Kindhearted Man’s Final Fight!” should be graded as one of those receipts, not as a standalone film.
Character Analysis
Monkey D. Luffy
Luffy remains the engine: simple desire, elastic tactics, zero interest in looking cool while winning. In “Advance, Law! The Kindhearted Man’s Final Fight!,” watch whether he drives the incident, reacts to someone else’s crisis, or refuses a compromise that would be “smart” in any other series. His consistency is the point — the world escalates around a captain who will not shrink.
Straw Hat crew and allies
Dressrosa typically spotlights different crewmates depending on island rules. Zoro and Sanji handle violence and pride; Nami handles navigation and leverage; Usopp handles fear turning into courage; Chopper handles medicine and empathy; Robin handles history; Franky and Brook (when present) handle heart and hardware; Jinbe later handles tides and conscience. This episode’s title — “Advance, Law! The Kindhearted Man’s Final Fight!” — is your hint for who the hour thinks matters.
Opposition / island forces
One Piece antagonists are rarely empty HP bars. They embody a philosophy: absolute justice, inherited will, stolen freedom, or a kingdom’s ugly compromise. Inside Dressrosa Doflamingo Colosseum, expect the opposition to teach the crew a rule of this sea. Even a mid-arc hour should clarify what winning would cost.
World Building
World rules visible in Season 17 Episode 78 stay local: how this island’s weather, government, Devil Fruit oddity, or cultural taboo constrains the crew. Dressrosa is the container; “Advance, Law! The Kindhearted Man’s Final Fight!” is one room inside it.
One Piece lore is famous for long payoffs, but this page will not smuggle future reveals into Episode 78. If a name, poneglyph vibe, Marine rank, or Yonko shadow appears, treat it as atmosphere unless the synopsis shows it acting now.
Geography still matters. Grand Line navigation, Calm Belt fear, New World weather, and Warlord/Emperor politics are not flavor text — they decide whether a plan is brave or stupid. When “Advance, Law! The Kindhearted Man’s Final Fight!” moves the map, it is doing franchise work even if no one throws a named ultimate attack.
Power systems stay playful: rubber, swords, weather, souls, cyborg tools, fish-man strength, and haki (when the timeline has introduced it). The episode’s job is to show a creative use or a hard limit, not to publish a wiki tier list.
Animation Review
Toei’s One Piece TV look has eras. Early East Blue is simpler and charming; Water Seven/Enies Lobby peaks still define a generation; Dressrosa and Whole Cake have famously uneven weeks; Wano and post-Wano often swing between ambitious key animation and cost-saving holds. Season 17 (Dressrosa) should be judged against its own production moment, not against a theatrical film.
For “Advance, Law! The Kindhearted Man’s Final Fight!,” expect the usual TV priorities: readable action, expressive faces, and comedy timing. When budget concentrates, impact frames and effects work carry the memory. When it does not, character acting and layout still sell sincerity. Kagex animation score 8.6 / 10 reflects peaks vs comfort cuts for this hour — not a YouTube sakuga compilation ranking.
Direction matters as much as raw drawings. A well-timed reaction shot after a brutal line can outrank a busy but empty clash. One Piece thrives when the camera respects silence between punches.
Music and Voice Acting
Score 8.2 / 10. The franchise’s needle drops — We Are!, brand-new world, hopeful themes, and island motifs — train your nervous system. Even without listing every OP/ED cour change, “Advance, Law! The Kindhearted Man’s Final Fight!” either rides that recognition or undercuts it with quiet strings.
Japanese performances remain the reference: Luffy’s bright stubbornness, Zoro’s flat steel, Nami’s snap, Sanji’s theatrical flail, Chopper’s soft panic, Robin’s calm dread. English dubs vary by era; do not wait on a preferred track to judge story.
Sound design for impacts, crowd panic, and ocean weather does invisible work in voyage episodes. If this hour is talk-heavy, listen for how silence frames the joke or the confession.
Hidden Details
- Title card language in “Advance, Law! The Kindhearted Man’s Final Fight!” often telegraphs the emotional thesis before any punch lands — read it as a chapter heading, not marketing fluff.
- Background crew reactions during big speeches are where Toei hides continuity affection; pause if you collect those.
- Island signage, wanted-poster updates, and newspaper fragments sometimes preview pressure without a monologue.
- Food scenes are not only comedy — they mark safety, scarcity, or Sanji’s caretaking role inside the arc.
- This page stays inside Episode 78; if a detail only makes sense after later episodes, it is not listed here as a “gotcha.”
Best Moments
- Title promise: the hour’s clearest delivery of what “Advance, Law! The Kindhearted Man’s Final Fight!” claims on the tin.
- Crew beat: a character choice that could only happen because earlier Dressrosa episodes happened.
- Opposition beat: a line or tactic that clarifies the island’s rule set.
- Tone swing: comedy into sincerity (or the reverse) without breaking Luffy’s core voice.
- Exit hook: the final push toward “To Be Free! Law’s Injection Shot Blasts!” that makes continuing feel obvious.
Pros and Cons
Pros: Sequential clarity inside Dressrosa; title-led focus; franchise sincerity; cumulative world pressure around Dressrosa Doflamingo Colosseum.
Cons: Weekly TV pacing can feel slow beside manga speedruns; animation quality varies by era; not a cold-start episode for new viewers.
Final Verdict

- Story: 8.5 / 10
- Characters: 8.1 / 10
- Animation: 8.6 / 10
- Music: 8.2 / 10
- Enjoyment: 8.4 / 10
