Ikaruga suffered an extremely fatal wound, was left to die, then the tower collapsed and blew up. In the manga it was extremely implied that she died, but the anime censored so much of that that they wrote her off as living through it. Ur died when the ice melted, and so many people said that that would happen if such a thing were to occur. Gray just theorized that she was alive in the ocean, and when Ultear went into the ocean, all she saw were records of Ur's memories. Ur, for all intents and purposes, is dead. Ultear also "doesn't exist in time," she sent a thought projection to the location of the time anomaly. She's still an old woman living in god-knows-where. And we never were told if Azuma died after he turned into a tree and just hypothesized that he was still living in this state. Right here, in this chapter, the author says that the magic is called Historia of the Dead and it targets dead people. These people are dead. That's just the bottom line.
