What is this? (English)

Ah, that's onee-sama's rig! It's dangerous! (Ship Girls' language)

Ah!

I-It's disappearing?

How creepy.

What is that commotion down there?

Commodore!

The townspeople have captured some bizarre foreigners, and it seem they are attempting to hang them.

Hmm, a savage bunch indeed... the people on this island are.

Should we stop them, sir?

No, ignore them.

We only came here from London to catch pirates. What happens on land is beyond our jurisdiction.

Ever since its discovery in 1492, European nations fought for dominance over the American continent. In an effort against the early contestants, Spain and Portugal, "late starters," England in particular, began issuing permits to irregular combatants that allowed them to attack and loot enemy trade vessels as a justified act of war. They became state-regulated pirates known as "privateers." With extension of hostilities into North America during the War of the Spanish Succession at the dawn of 18th century, privateers engaged in commerce raiding across the Atlantic Ocean.

In 1714, when the Treaty of Utrecht put an end to the War of the Spanish Succession, privateers lost their purpose. However, many of them refused to settle for a lawful profession and instead turned into real pirates — aligned with no nations, targeting ships sailing under any banner, even that of their former homeland. Reinforced by other disgruntled sailors, they soon grew in numbers as they rampaged across the Caribbean. That period came to be known as "the Golden Age of Piracy."
