That's hard to say. Given that Yu essentially just blew up in Mika's arms with enough power to split the clouds, Mika could be incapacitated. However, I think Mika will probably do everything in his power to try and save Yu. Since the power of angels will completely take him over and do that hive mind destroy-all-the-sinners thing while utterly erasing his will, it could be that the only way to quiet down the power of angels is to balance it out by turning him into a vampire. The reason the seraph kids have been so successful wielding black demons could because the power of angels and demons within them keep each other in check. Since vampires eventually become demons, this could work. This might also explain why Mika is so abnormal for a vampire; the angel part of him has minimized the typical personality changes.

I don't think Yu will die because he is the only person connecting Mika with Shinoa and the others. However, it is possible that Yu might end up in a coma for a long while or something. The last time he transformed, the transformation was not nearly as major, but he still slept for a week. By the sound of things, Asuramaru is not expecting Yu to return to normal ever again. He could end up with some kind of permanent damage or change.
