Like Sephiroth before him, Kadaj’s trip into the Lifestream does not actually kill him. He eventually revived himself along with two more Remnants of Sephiroth, Loz and Yazoo, inside the Northern Cave Crater as the Turks were collecting Jenova's head. The three of them effortlessly defeated the Turks before deciding to locate Jenova's head, that of which the Turks had somehow managed to escape with.
Another awesome cosplay by Saya! Every time I see her cosplay photos, it makes me sad that we will never be able to see new ones from her anymore. Thanks again to Sheila for sending this in!
