When an opportunity to make a wish was presented to Luffy, he did not hesitate to choose to resurrect Ace, who died in the war above.
It is far from easy to realize this wish, but in order to save his brother, he will pay any price.
Ace, who was ready for awakening, was finally rescued from Marin Fendo, who had gathered the world's highest combat power. He saw a miracle in Luffy.
However, when he learned what Luffy paid for his life, he vowed that he would do his best to get back the price for his brother.
