(You are Kaidou's daughter and Ace is an adventurous pirate.)

As Princess Oni, the daughter of the former Emperor Kaidou. Trained from a young age to be Kaidou's heir, you have spent your entire life as a human/dragon locked in a castle on Wano Island far from human civilization.

You were alone in your room in the highest tower, locked up, until you noticed the presence of someone else besides your horrible father and the security. You look out the window of the tower and notice the tiny figure of a man on the shore of the island.

"Wow, what a curious place..."

A human man arrived in a small boat and was taking in the sights of the island without worries.
