The names of Roxas's Keyblades in Kingdom Hearts are "Oathkeeper" and "Oblivion".

The answer is true because Roxas wields two keyblades in Kingdom Hearts: Oathkeeper and Oblivion. Oathkeeper represents Roxas's connection to his friend Kairi and his memories of their time together, symbolizing his determination to keep his promises. Oblivion, on the other hand, represents Roxas's darker side and his acceptance of his fate as a Nobody, signifying his willingness to embrace the darkness. Both keyblades hold significant emotional and thematic relevance to Roxas's character and journey in the game.
