Eliminating the Pirates

I heard Guon the bellflower is planning something. What would that be?

Guon had a plan to release the Bellflower that were being treated as slaves to the pirates. Unfortunately, he couldn't do it by himself, and asked me if I could go up to the pirate ship and defeat 200 Lord Pirate's Devoted Krus and 200 Lord Pirate's Devoted Captains. There are many different types of pirates under Lord Pirate, and the ones in command act differently from others. Apparently, they only make a quick appearance, then disappear. I better remember how they look, and eliminate the right ones.

Lord Pirate's Devoted Captain [progress]

I was able to defeat the Lord Pirate's Devoted Krus and Lord Pirate's Devoted Captains at the pirate ship. Unfortunately, there are still plenty of pirates, and Lord Pirate is still alive and well. Wiill this be enough to save those Bellflowers?
