Short Summary
After the death of Sabo, Kuina and Zoro continue their training while the others discover the Revolutionaries' ship. Meanwhile, Dragon tells Ivankov that he has attracted too much attention and departs for Baltigo. At the Grey Terminal, the villagers begin to accumulate more junk. At the forest, Ace becomes more fond of Luffy as a brother when Luffy gets nearly mauled by a bear. After seven years of intensive training, Ace departs from the Goa Kingdom to the ocean and Dadan is emotionally distraught. Three more years pass and Luffy bids farewell to everyone as he departs on his journey to the Grand Line. Luffy encounters the Sea King that ate Shanks' arm again and uses the Gomu Gomu no Pistol technique to defeat him. In the present, Luffy is still upset that Ace has died and proclaims to Jinbei that he is too weak.

Long 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 seven years later, bidding the mountain bandits and Luffy farewell. Dogra comes by a few months later and shows Luffy a newspaper that talks about Ace and his new crew. Three years later, Luffy sets out from the Goa Kingdom. He then beats up the Lord of the Coast for eating Shanks' arm and to show the results of his forest training.

Present time: Luffy proclaims that he is weak in front of Jinbe, implying that he can't be the Pirate King like he wanted, considering that he wasn't able to protect Ace or his friends.
