Yuki

Yuki was the mysterious little ranch girl who lived on a remote island on a ranch where the giants celebrated. She was responsible for starting a duel between Dorry and Brogy.

History
She appeared in a small flashback at the end of the Little Garden Arc over 100 years ago in 1422 AOS. When Dorry and Brogy caught two huge Sea Kings, she bet them to see which is bigger, starting the duel between the two giants.

This bet became a duel and eventually the reason for their duel was forgotten. It is unknown what happened to Yuki after that.
