Cavendishs Sleeping Hakuba Persona
Status: confirmed (payoff on-page Ch. 734 ) · Technique: name-etymology
The seed
Ch. 704 — the name’s Jekyll-and-Hyde / white-horse loading
Cavendish is introduced with a name long flagged for its Jekyll-and-Hyde resonance (the novel’s “Cavendish Square”) and a fairy-tale “White Knight ” / white-horse billing (his steed Farul ). His etymology note carries the dual-nature reading from the start — a clean name-level setup for a hidden second self.
The payoff
Cavendish ’s murderous alternate personality is named Hakuba (白馬, “white horse”) — a sleeping split personality and superior swordsman who surfaces only while Cavendish sleeps (pp. 8, 13). Hakuba cut down the entire remaining Block D field in a blur of “slicing winds” (pp. 9–12) and was the night-killer behind the “Slicing Winds of Rommel ” in the Kingdom of Rommel Hakuba is Cavendish’s own epithet , 白馬のキャベンディッシュ (“Cavendish of the White Horse,” VIZ “White Knight”) — so his murderous sleeping self literally bears his own title; in Rommel the legend was the “Kamaitachi of Rommel ,” naming him after the kamaitachi slicing-wind yokai (and mirroring Jack the Ripper, the uncaught night-slasher of Victorian-London-styled Rommel). The Jekyll-and-Hyde / white-horse name-loading pays off literally. payoff_chapter: 0734 (≤0747, in-window).

Why this matters
A clean name-etymology foreshadow: the dual-nature resonance baked into “Cavendish” (Jekyll-and-Hyde “Cavendish Square”) plus the white-horse motif of his “White Knight” billing pre-loaded a literal split personality whose very name — Hakuba , “white horse” — is the same motif made flesh. Oda routinely pays off a character’s name straight; here the payoff lands in the same chapter it is revealed.
