A six-note chekhov-explicit cluster fired across one window (Ch. 613–Ch. 626) that builds the Poseidon Ancient-Weapon identity onto Princess Shirahoshi without ever speaking the name “Poseidon” . The cluster moves in two beats: first the why-is-she-hidden mystery (a heavily-guarded, abnormally-giant princess sequestered for ten years because someone wants her dead), then the what-she-is reveal-of-mechanism (she unconsciously summons the Neptunians/Sea Kings — the once-a-few-centuries mermaid of the Ryugu royal legend, a power that “could sink the entire world”). It is the on-page spine of the partially-confirmed The God-Triad Names Encode Each Ancient Weapons Deployment Domain (sea-member leg) and the identity premise the near-term Vander Decken Hurls The Ark Noah At Shirahoshi As The Fish-Man Island Arc Weapon relies on.

Why it matters
The cluster is the densest single-window install of an Ancient-Weapon identity in the captured run: five chekhov-explicit seeds at one target, the mechanic (Sea-King command) demonstrated on-page, and the only withheld element the proper noun. The name landed on-page Ch. 649 (Neptune → Robin) — the cluster is now confirmed.
