Kiba’s relationship with Cheza is not a romantic one, despite how it may appear. The relationship is that of a platonic love. As the chosen wolf, Kiba is bound to Cheza by fate. He will protect her at any and all costs.
The finale of Wolf’s Rain is somewhat vague, but here’s how it’s been interpreted. First of all, everyone did in fact die, including Kiba. He might have gotten a glimpse of Paradise before the end, but he did, in fact, succumb and pass on. This is sad, but it’s okay because they’re all reincarnated.

Toboe was raised as a pet by Granny, an elderly woman whom he accidentally killed in an unrestrained act of playfulness. The silver bracelets on his wrist are all he has left of her. Because of this, Toboe maintains an affection for humans that none of the other wolves can understand (with the exception of Blue).
