You can have similar personalities without being a reincarnation you know, and given what we know of the nature of the soul in Remnant reincarnation is just not possible.

Unlike most worlds, the soul if a physical thing that can be moved between hosts using technological means, when you die it's gone, reincarnation be damned.
