To Fulfill the Promise - Separate Departures!

Summary

Ace starts to care for Luffy more as a brother after he was nearly mauled to death by a bear. Ace then sets off on his own 7 years later, bidding the moutain bandits and Luffy farewell. Dogra comes by a few months later and shows Luffy a newspaper that talks about Ace and his new crew. 3 Years later, Luffy sets out from the Goa kingdom. He then beats up the local sea monster for eating Shank's arm and to show the results of his forest training. Present time: Luffy proclaims that he is weak in front of Jinbe (and possibly the whole island), implying that he can't be the king of pirates like he wanted, considering that he wasn't able to protect Ace or his friends.
