After leaving Diana's brother behind we each went to a pirate ship, from what I've observed these pirates have a maximum strength of Grade +B.
These pirates are very weak so only one of us will be enough for each boat, plus there's a Fairy or spirit of the space element with each one to help carry the pirates' storage items.
In my case, I have Layla coming with me since I can't let this psycho Fairy go on a boat alone.
Once I got on the boat I spread my Aura while blending it with the surroundings, this allowed me to form a real-time image of the entire boat.
With that I saw that there were only five pirates here, apart from them there were some people wearing chains, they must be illegal slaves.
