Roxas, the Key of Destiny (めぐりあう鍵 Meguriau Kagi?, lit Serendipitous Key), is the Nobody of Sora and was Rank XIII within Organization XIII. He was born when Sora released his own heart in order to restore Kairi's. Although Sora's heart was soon restored, Roxas continued to endure and exist, oblivious to Sora's existence for most of his life. He has the ability to use the Keyblade, and wields light, using it to direct rays that strike opponents with great power. He commands the Samurai Nobodies.
Roxas was also one of the mysterious hooded figures in "Another side, Another story..." and "Deep Dive". During the prologue of Kingdom Hearts II, the player controls Roxas for a short time until Sora is awakened. In Kingdom Hearts 358/2 Days, Roxas is the main protagonist.
