will he sail at 17 like the others? if so he wil sail 2 years before ace, so that means he could spend these two years exploring the blue seas before entering the grandline
I originally had him set sail at 17, but I changed it after thinking it over. He will leave with the Revolutionaries to train for a few years before leaving when he is 15. Meaning 4 years before Ace sets sail and 7 years before Luffy does. Giving him plenty of time to explore while preparing for future events.
