After finishing both halves, we watch a scene from the 358/2 Days timeframe. Roxas and Axel are atop the Twilight Town clocktower talking about a promise, then Roxas suddenly disappears.
Axel suddenly awakens in the computer room of Radiant Garden/Hollow Bastion. He has stopped being a Nobody and is now the human known as Lea. He finds his partner scientists from pre-Nobody – Dilan (Xaldin), Aeleus (Lexaeus), Even (Vexen), and Ienzo (Zexion) – on the floor.
Then he realizes that, he, too, has become human (Lea), but only those who joined Organization XIII. Of course, no one cares about Xehanort (Xemnas), but what about Braig (Xigbar) and Isa (Saïx)?
(There are more… What about the human forms of Larxene, Marluxia, Demyx, and Luxord? We know where Roxas went, and Xion was…)
You’ll also receive the Chronicle entry on Kingdom Hearts: 358/2 Days.
So, next world?
