It's a small detail amidst the craziness that is the rest of 252, but I'm losing my absolute mind at the fact that Past Allen was apparently soldier.
We just had it confirmed that our protagonist, our child soldier protagonist, had a whole previous life that he lived and completely forgot about. He had a whole first life where, until he was at least an older teenager, he had nothing to do with the inescapable holy war that's taken over his existence the second time around. He was just some kid with no connection to the battle between the Noah and the Black Order.
But what was he instead? Was he free to actually have a childhood in this other life?
Nope! He was just a normal soldier in some non-spiritual, completely mundane war, and he would have died in battle if Nea hadn't swept in and drafted him into the holy war instead. There is no life in which the young Allen is not a soldier.
