Debut during the Alabasta arc
"No matter where we are, or what we're doing, we will always be together, and so on this day forward, we are forever siblings!"
Rin Ayame, Luffy, Ace, and Sabo were all raised by the Dadan Family. Garp found her during one of his missions and dropped her off for Dadan to take care of her. After Ace had left and Sabo was gone, it was just her and Luffy, they hang out with Shanks every time he came to the island and coincidentally she ate a Chi-Chi no mi, soon Garp came and took her away for her to train in the marines.
Now she is a sergeant in the marines and one of the assistant officers for Captain Smoker, and now what will she do when she finally sees Luffy at Alabasta will she leave the marines and become a pirate like her other brothers, or will she stay as an officer. ( Sorry for the bad description)
