So... Did he just outright kill whoever that kid was before then? What does "reincarnation" mean here?
I realize this could get really philosophically fuzzy if we say something like, "he reincarnated with his same soul, and then suddenly his memories were overwritten by his old self once his new body reached 5".
On the other hand, if the translation was accurate ("a spell that separates the memory from the soul") it seems moreso implied that his own soul actually died (contrary to the general implication of "reincarnation") and he just randomly overwrote some kid's mind with a copy his own (which is, ethics aside, a totally rational thing to do if his goal was indeed simply to finish work left unfinished, as he claimed). But that's
really philosophically mucky... >_>;

So yeah, my reading is both he and the kid have suffered a continuity failure in a sort of bizarre murder-suicide (a brain-wipe and effective death for the kid, a more straightforward death for himself), and what's left is person #3, a carbon-copy of his original self in the kid's body.
