Quick recap
A 2015 TV special telling Sabo's life from his side. Born a noble, he runs away and grows up on Mt. Corvo with Ace and Luffy as brothers. When he tries to set sail, a Celestial Dragon fires on his boat, and Dragon rescues him, but Sabo loses his memory and joins the Revolutionary Army. It only comes back when he reads the news of Ace's death. The special then retells Dressrosa from his angle: reuniting with Luffy, winning the Colosseum tournament and eating the Flame-Flame Fruit to carry on his brother's fire.
