One of the Four Blues · native habitat of the island whale species · first named in current-scene context: Ch. 103
Profile
One of the Four Blues flanking the Red Line / Grand Line system. Establishes the One-Piece-world geography as four-quadrant rather than two-quadrant. Native habitat of the island whale species (per Crocus’ Ch. 103 explanation that Laboon is a West-Blue native).
Etymology
West Blue (English) / Nishi no Umi (西の海, “Sea of the West”). The Four-Blues nomenclature is cardinal-direction-anchored — the seas are named for their position relative to the Red Line junction.
Key chapters
- Ch. 103 page 18 — first on-page named reference in a current-scene context. Establishes that island whales are a West-Blue-endemic species.
- Ch. 104 page 11 — first on-page application as a populated character-origin in a stakes-bearing context. Crocus: “His home is the West Blue, which lies on the other side of the Red Line.” — pre-loads the Rumbar Pirates / Brook West-Blue-origin reveal (~Ch. 488). The four-Blues-symmetry plot-architecture gets its first West-Blue character-anchor here. Cross-link West Blue First Named As Laboon Home (new).
