Long Summary
On a hill in Carta lies Kyros' house, where Kyros, the Straw Hats, Law, Kin'emon, Kanjuro, and Bellamy rest and recover from their injuries. Kyros explains why he lives here and offers the group anything they may need, and Kin'emon asks why Bellamy is with them, to which Law replies that Luffy knows him. Kyros, Usopp, and Law fall asleep from exhaustion, and the door of the house begins opening. Zoro tenses up at the intrusion, but the person entering turns out to be Sabo, who throws Zoro a drink. Sabo approaches Luffy, and Robin goes to wake him up, but Sabo states that she does not need to do that. Franky asks if he is leaving soon, which Sabo affirms, revealing that CP-0 is heading for them. The Straw Hats prepare to leave soon as well, but wonder why Luffy never told them about having another brother. Sabo reveals that he was presumed deceased for a long time after getting into an accident.

Twelve years ago, in Goa Kingdom, a ten-year-old Sabo asked about the country's plan to set fire to Gray Terminal. However, he was shocked to receive callous remarks about a plan that would kill many people. Sabo ran to warn Ace and Luffy, but he ended up beaten and lying in an alleyway. He was approached by Monkey D. Dragon, and told the mysterious man about his contempt for the town and his status. Feeling trapped, Sabo decided to set out to sea, but encountered a ship much larger than his small vessel. The large ship contained the World Noble Jalmack, who shot Sabo's ship with a bazooka due to it crossing his path. Sabo desperately tried putting out the flames, but the second shot completely destroyed his ship, sending his tattered hat flying into the water.

Barely alive and with an injury around his left eye, Sabo sunk into the depths of the ocean, but was saved in the nick of time as Dragon grabbed his hand and pulled him out of the water. On a ship belonging to the Revolutionary Army, Emporio Ivankov and the revolutionaries grew anxious about when Dragon would return. Dragon then arrived with Sabo in his arms, and the ship's doctor was called. Sabo eventually woke up surrounded by revolutionaries. One of them asked if his name was Sabo due to it being written on his possessions, but Sabo had no memory of his name or anything at all. Another revolutionary decided that they should take him home and find his parents, but Sabo refused, having a bad feeling about his family despite not remembering them. Ivankov stated that they can't let him stay here, and Sabo replied that they could take him somewhere else. Dragon and Bartholomew Kuma then approached, and Ivankov asked Dragon what they should do.

In the present day, laborers work on rebuilding the palace as the Corrida Colosseum gladiators are taken to a room inside, with the worker promising them asylum from the Marines and a doctor. Boo wonders if there will be a banquet, but is told that it will be later. The gladiators prepare to go to sleep, especially Cavendish, but Bartolomeo knows what will happen if he goes to sleep. He tells people to bring him a chain, which he uses to wrap around Cavendish, telling the outraged gladiator that they will see a monster if they do not do this.

At Kyros' house, the Straw Hats ask Sabo if that was how he joined the Revolutionary Army, and Sabo replies that it was sort of like that. 12 years ago, Sabo trained on Baltigo with several children under Hack, but broke off from the exercise. Sabo told Hack that he was going to train himself before running off, and Hack told Ivankov that Sabo had a lot of fighting experience which his body still remembered. The days passed, with Sabo training and studying intensely. One day, Sabo fought Hack and succeeded in removing the fishman's belt, causing his pants to fall down. He was then approached by Kuma, and was excited to fight him next, but was easily blown away. Meanwhile, Ace and Luffy sat on the coast Dawn Island, promising to get stronger and become pirates at age 17. Two years later, Sabo peeled potatoes with Koala, but was exasperated when they were given another box. He decided to break into the apples and eat them, but was reprimanded by Koala. Later, he fought Kuma once again, who sent him flying into a pile of boxes. However, Sabo discovered a pipe inside the wreckage, and he used it to vault off Kuma and attack Dragon. Dragon avoided Sabo's blow and knocked him out, but commended his fighting ability.

Seven years later, Ace set out to sea to become a pirate, and the Revolutionary Army is engaged in battle with a military fortress. Hack and Koala sat helpless in the trenches, wondering what the people sneaking in first were doing. Right then, Sabo called them, briefly stating that he would figure something out before hanging up. Sabo then appeared right in front of the entrance and ran toward it despite enemy fire. He hardened his arm with Busoshoku Haki and broke down the door, entering the fortress with ease. Sabo dispatched the enemy soldiers as the other revolutionaries freed the captured citizens and allies, and as he was surrounded, Sabo completely destroyed the fortress by using Ryusoken. At Baltigo, Sabo was commended for the victory, and a revolutionary talked about a rookie around Sabo's age who refused to join the Shichibukai. He began to say Ace's name, but Sabo completed it, stunning them. However, Sabo could not remember what he said. Three years later, Luffy headed out to sea and faced Lord of the Coast as a 20-year-old Sabo went to sea as well. In the present, the Straw Hats ask Sabo how he regained his memory, and Sabo grows tense as he reveals that Ace's death reawakened it.
