Chapter 257: Dial Battle

Arc: Skypiea · Saga: Sky Island · Released:

Summary

Aboard the Going Merry chugging up the Milky Road, the Sky Knight (Gan Fall) turns a smashed barrel into a tutorial on Dial combat tech. He has Sanji hammer a shell-loaded barrel and — to everyone’s shock — the barrel beneath is unharmed: it is an Impact Dial, which absorbs any impact delivered to it and releases it on command, powerful enough to kill an average person. Gan Fall walks the crew through dial weaponry (the Reject Dial, Flame Dial, Heat Dial, Axe Dial) and then explains Mantra: the power to “listen” — those born with the gift hear the voices all living things emit and can read a foe’s next move, with range scaling to mastery (his own reach covers all of Upper Yard; Enel’s extends over the entire country). Up at the ark/throne, Enel — amused that two priests (Satori, then Shura) have fallen “two in two days” — orders the 50 Heavenly Warriors (his enslaved soldiers) to flush out the invaders: “30 Shandians and 7 Blue-Sea people.” On the ground, Wyper rallies the Shandians for a do-or-die push (“Enel’s head will roll today”), readying his Reject Dial despite a comrade’s warning that reusing it will blow him apart. The Shandians scatter — “every man for himself,” reconverge at the Kami’s shrine — and one is ambushed by a Heavenly Warrior swinging an Axe Dial, only to cut the warrior down (“Your shield is useless!”). Meanwhile a lost, lonely Luffy, hunting the source of a goofy little song he mistakes for a goat, blunders into the Shandian woman Raki in the jungle — and the two recognize each other.

New reveals

• Impact Dial mechanics: a dial that “absorbs any impact delivered to it, then releases it at the user’s discretion.” Sanji’s full-power barrel-smash leaves the underlying barrel uncracked; “the shell absorbed the brunt of the impact.” If used properly it is “powerful enough to kill the average person.” Often worn on the hand with a bandage or glove (pp. 3–5). Gan Fall identifies it as “what that ball-brained vassal used” — i.e. Satori’s springy counters (p. 5).
• Reject Dial: named/described — an Impact-class dial said to “emit ten times the force of an Impact Dial.” So destructive that “the wielder’s life is endangered by using it” (p. 6). Wyper carries one (pp. 11–12).
• More dial types catalogued: Flame Dial (stores fire — a “searing hot heat javelin” when combined with a spear; placed in a bird’s beak it makes a fire-breather), Heat Dial (everyday use — warm a pan to cook without a fire) (pp. 6–7). “Dials can be very helpful… It all depends on who uses them.” Axe Dial shown in combat (p. 16).
• Mantra explained for the first time as a mechanic (not just demonstrated): “Mantra is the power to listen. Just by being alive, humans emit voices from their bodies. Those born with the gift of Mantra can hear them and know a person’s next move. The more the user has mastered Mantra, the greater the area they can listen to.” Gan Fall’s range = “all of Upper Yard”; Enel’s = “the entire country… that is how far his power extends. It is the one power that no one truly understands” (pp. 7). Gan Fall: “I do not command the power myself.”
• The 50 Heavenly Warriors: Enel’s standing force (the former Heavenly Warriors he enslaved, per Ch. 255) — 50 angel-winged soldiers ordered to attack (pp. 9–10, named in caption “The 50 Heavenly Warriors of Skypiea”).
• Survival-game headcount: Enel tallies the invaders as “30 Shandians and 7 Blue-Sea people” (p. 9).
• Wyper’s resolve: “Even if it means abandoning your comrades… only those willing to push forward at any cost… Enel’s head will roll today.” Willing to die using the Reject Dial — “Isn’t that what you’d call commitment?” (pp. 10–12).
• Luffy / Raki encounter: Luffy finds the Shandian woman Raki in the jungle; mutual recognition (“Hey… it’s you!” / “What the heck are you doing here?”) (p. 19).

• Cover: Wapol cover-series, “Wapol’s Omnivorous Rampage, Vol. 19: ‘Wapol’s Toy Shop Expands!’”

Notable panels

• Page 1 — Title splash + cover: “Wapol’s Omnivorous Rampage, Vol. 19 — ‘Wapol’s Toy Shop Expands!’” A grand crowned “TOY SHOP” storefront; Wapol roaring with laughter in front of it, a small robot/toy figure at left. (Cover-story B-plot; the Wapol “toy empire” runs across this batch.)
• Page 3 — “BLOOP” — Sanji’s barrel-smash absorbed; the empty barrel below is uncracked. The first visible proof of an Impact Dial in the crew’s hands.
• Page 5 — The shell shown face-down on the barrel, polka-dot Impact Dial design; Gan Fall: “…is an Impact Dial.”
• Pages 9–10 — Caption-introduced “The 50 Heavenly Warriors of Skypiea” — ranks of winged soldiers raising a war-cry (“DO-OOM!! BAA!!”) as Enel orders the riot.
• Page 11 — Wyper’s bird Fuza wheels overhead (“KRA KAW!”); Wyper fires the Reject Dial (“DA-DUMM!!”) as a comrade screams the warning.
• Page 16 — A Heavenly Warrior swings an Axe Dial (“ZAH!! Axe Dial!!”); the Shandian counters — “Your shield is useless!! SLICE.”
• Pages 17–19 — Luffy chases a goofy song (“My head is empty, I’m a fool… Humdy dum! There’s a lovely island in the south…”), convinced it’s a goat (“BAA!!”), and finally rounds a rock to find Raki — mutual “it’s you!” recognition. (Comic counterweight to the dial-battle A-plot.)
• Page 20 — SBS column (Vol. 28). Notable Q&A: Oda defines “Will” as “willpower… having a strong heart… an intense desire” — thematic gloss relevant to the Will-of-D motif.

Open questions raised

• Will Luffy and Raki cooperate, or does she still take him for a Heavenly-Warrior deserter (the Shandian assumption from Ch. 255)?
• Can the Reject Dial be wielded without killing the user — and will Wyper survive using it again?
• How will the Straw Hats acquire/deploy Impact Dials of their own now that Gan Fall has armed them with the knowledge?
• Is Enel’s “country-wide” Mantra truly absolute, or does it have a blind spot the heroes can exploit?
