After going into the sea, I met the witch.

People are in a mysterious world; they open their eyes and find themselves already at sea.
The story begins with the protagonist being framed and rescued after a difficult ordeal. However, the captain turns out to be a ruthless witch who is indifferent to life and kills without hesitation.
How to do?
Fortunately, I have a cheat code!
An unnamed, jet-black ship sculpture led Ryan on his journey through the heavens.
This shark is on the verge of death because it witnessed a highly private rendezvous. If you save it, in return, it will take you to join them.
This planet is dead, all life has been wiped out; it seems like a good source of material for a long-range warship?

My name is Freyne, and I am the captain of the "Black Rose." On the surface, I am a fledgling female pirate, but in reality, I am the fifth princess of the Augustus Dynasty who has just escaped, and a sea witch who has just awakened.
To escape the pursuit of the "Despicable Ones," I had no choice but to set sail, carrying the treasure map passed down through my family, to the depths of the ocean in an attempt to find the lost treasure and restore the dynasty!
On the way, I rescued a drowning person.
The good news is that this guy is very knowledgeable and can serve as the navigator of the "Black Rose".
The bad news is that this guy is really weird. Not only does he say things that are hard to understand from time to time, such as "Captain, what do you think it would be like if the sun were a warship?" or "Pirate King, here I come!", but he also brings back some strange and unusual things every now and then!
