I figured it would be best to review both of these arcs at the same time. Not because they are that heavily related, but more so because they are both really short and there wouldn’t be much to say about just one of them.
This is the point of the story where the Straw Hats are going to this “Grand Line”. This terrifying part of the world where the strongest pirates sail free. The part of the ocean where storms can hit in an instant, and be gone the next. The part of the world that the Pirate King, the worlds strongest swordsman, and a brave warrior of the sea need to conquer.
This was the real start of the Straw Hat’s journey, and this ocean would be the place where many of their dreams would come true, or be crushed.
Logue Town is the last city before the Grand Line, so the Straw Hats decide to stop there and get some supplies. Zoro is in need of a few swords since Mihawk destroyed his, Sanji needs some food for the ship, and Luffy wants to see the town where Gol D. Roger, the king of the pirates was born and was executed.
Not much happens for Usopp and Nami other than regular shenanigans, and Sanji just gets some food for the Going Merry.
Zoro and Luffy have the interesting moments in this arc, and they’re pretty interesting because of what they show for those characters.
Luffy wants to see the spot where Gol D. Roger was killed, and eventually gets nearly killed by Buggy. The moment before his death, Luffy smiles and a lightning bolt saves him from getting his head chopped off.
This was the first instance where we got to experience the Will of D. Not much is known about it, but one thing we do know is that everyone with the name D. dies with a smile on their face. Luffy was smiling the moment before his death, and Smoker (a captain in the Marines chasing Luffy) notices this and notices the similarities of Roger and Luffy.
We know Luffy is destined to do great things because he is the main character, but this was the first chance we got to notice Luffy’s connection to Roger.
On the other hand there is Zoro. He’s going sword shopping, and is rather poor. Luckily he comes across Tashigi, a near-blind Marine when she doesn’t have her glasses on, who helps him find a rather good and rare sword basically for pennies.
The other sword he is looking for he gets by throwing it in the air, and betting the sword salesman that if it cuts his hand off, then he doesn’t get it, but if the sword spins over his arm and doesn’t cut him, then Zoro gets it for free…and guess what happens.
Yes, the sword spins over Zoro’s arm and doesn’t hurt him, and the swordsman, believing that the cursed blade belongs in Zoro’s lucky hands, gives him the sword for free. As it turned out, this sword was even more rare than the sword he got for cheap.
Another big part of this arc is the occurrence of Smoker and Dragon. Smoker, who ate a logia devil fruit, gives Luffy some trouble because nobody can actually hit him. Thanks to Dragon, who we discover is Luffy’s dad later on, stops Smoker and helps Luffy et. al. escape.
This sort of sets up Smoker as the “rival” of Luffy in the Marines. Coby is supposed to be I think, but I like the idea of Smoker being the rival like Gard was for Roger.
Reverse Mountain Arc doesn’t offer much in terms of story. Basically the only thing that happens is that the Straw Hats make it over Reverse Mountain and into the Grand Line, where they meet a man named Crocus, who they learn worked on Roger’s ship.
They also meet Laboon, which becomes a pretty important whale later on in the story.
There is a brief moment of camaraderie when they all pledge to achieve their dreams and conquer this ocean.
In terms of the overall story, these two arcs don’t offer much. I think together they take up less than 10 chapters, but their impacts are huge for the rest of the story.
