Yes, and because of this, anyone defined to be dead can also be physically alive. Therefore, “dead” doesn’t mean dead as we think of it most of the time, not just for Kanon, but for anyone at all. There is absolutely no method contained within the text itself to distinguish this as being an exclusive property of Kanon, as the Battler case proves. “Dead” could mean “biologically deceased” in some cases, but it cannot be proved when and where this is applicable.
