OVERVIEW OF 358/2 DAYSAfter inducting Roxas into the Organization, Xemnas places him under Axel's tutelage. Initially, Axel was unsure how to treat Roxas, as he acted like a "zombie." Over time however the Nobodies begin to bond, eating sea-salt ice cream together at the Twilight Town Train Station after missions. As their friendship grows strong, Axel began to demonstrate emotions due to his time with Roxas. Axel is also present when Xion joins the Organization, but is sent to Castle Oblivion to deal with the traitorous Marluxia and Larxene as they intended to use Sora's powers to usurp Xemnas with Namine's ability to alter Sora's memories.
When Axel returns to The World That Never Was, he feels that Roxas has replaced him with Xion. Axel becomes jealous, not sure exactly what to make of Xion. At Roxas's suggestion, the three begin to spend time together as a trio. Some time later, Axel finds himself before Saix, and reveals that he regrets not being able to talk with Saix as he could with Roxas and Xion. Saix reminds Axel of the friendship they shared before becoming Nobodies, and the plans they had to take over the Organization.
After learning of her true nature, Xion attempts to leave the Organization before Axel eventually catches her in front of Roxas despite his pleas. With him and Roxas not on speaking terms, Axel soon becomes torn between his attempt to save them both from Xemnas's intent to do with any one of them. While assigned to a mission in Wonderland, Xion runs off and Axel makes no attempt of stopping her once she knocks out Xigbar. A few days later, with Roxas learning of Xion's identity and that Axel kept it from him, he leaves the Organization. Axel, who has enjoyed the time he spent with his best friend, is distraught by Roxas's decision as he tried to reason with him.
The next day, under orders, Axel tracks Xion to the Old Mansion in Twilight Town where he realizes her intentions, telling her that he's fed up with her and Roxas being selfish and doing whatever they want, before he manages to knock Xion unconscious. But the fight took its toll as Axel faints from fatigue once he brings her back to the Castle That Never Was, with Xemnas taking Xion from him. Later, in his quarters, learning of the aftermath of Roxas and Xion's battle, a depressed Axel discovers a Popsicle stick which reads "WINNER", a gift left by Roxas.
