Ryu Yun-Seo

Old pirate who has been sailing on the same boat since he was a child, and has been the first mate for the past few decades. Yun-Seo loves art and drawing and is a quite talented artist. Very calm and patient, but his preference to sort things without violence must not be mistaken for weakness. Despite his age, Yun-Seo is a dangerous opponent and knows how to handle a sword well.

Yee.

Yun-Seo's mother left him at his father's ship when the boy was 6 years old. He was taken in by the crew and grew together with the captain's own son. They saw each other as brothers and grew very close, later becoming a dangerous duo. Yun-Seo later on became his brother's first mate and also helped him to raise and train his two children. Unfortunately his brother also met his end, but Yun-Seo stayed on the ship and as the first mate - still looking after the young captain and his sister, making sure they don't do anything stupid.
