Two Become One (めぐりあう二人, Meguriau Futari?, lit. "Serendipitous Duo") is a keychain for Sora's Keyblade that is found in Kingdom Hearts II Final Mix, and a form of Roxas's Keyblade that is found in Kingdom Hearts 358/2 Days. In Kingdom Hearts II, it is obtained by defeating Roxas at Memory's Skyscraper. Two Become One represents Roxas, a fact borne out by its obtainment, appearance, and ability, Light & Dark, which causes the activation of any Drive form to put Sora in either Anti or Final Form. In Kingdom Hearts 358/2 Days, Roxas and Xion can wield this weapon by equipping the Zero Gear ⑤ with two Ability Units.
