Bring the brats over here in five minutes!!” (p. 9) — a giant drakkar splashes down into the sea clouds. “We can sail at any time” (p. 15).

See Imu Identity, Imu’s Body Cannot Withstand The Outside World.

Etymology: “Sommers” ← George Somers (English privateer-knight, colonizer of Bermuda) + echo of Martin Sommer (Nazi camp officer, notorious for sadism). Family Shepherd = English sheep-herder — ironic for a Knight who herds Elbaf’s giant children like a flock toward torture; shared with Gorosei Shepherd Ju Peter (Jupiter). See Shepherd. Source: One Piece Wiki (Shepherd Sommers).
St. Sommers — the immortal Shepherd-family Holy Knight — is shown at God Valley ~38 years ago, corroborating Holy-Knight longevity. He captures the prize Shakuyaku and, on Garling’s behalf, resolves to murder her rather than let a rescuer take her (“If you don’t say anything, it goes in the books as an accident!!” / “This ain’t no fairy tale!!”). He is cut down by Rayleigh’s “Spider Lily Steel” (pp. 14–18). (recent-chapter; flashback appearance — HOLD scalars. Verify physical-design continuity with his present-day portly depiction; identity inferred from the exact name “St. Sommers” + established Holy-Knight immortality.)
