You know, I never though Saruka would die. That's acually shocking and I'm curious to know how you're going to die and if someone kills you how are they going to pull it off?

As for T'lula, she's immortal, how is that possible? Is she fading?

/her immortality relates to the fact that she wont die from effecs from jutsu she uses or age. She however can die from fighting and being killed from things such as weapons.

Saruka's going to die because of the jutsu he used on kokujo to revive him. remember, it took some of his lifeforce.

sephiroth will be killed at the hands of roxas.because little does roxas know,sephiroth was that unknown ninja who killed his parents.HA!bet you didn't see that coming.
