Now that I think about it, you are right about the whole film theory thing. Either way, you get bonus points too lol.

However, the plot armor explanation is an out of universe explanation, whereas this is a lore wise one. While I'm clearly over analysing and bushi would never admit to something like this, it can provide a better explanation other than luck for these characters getting the hands of deities.

out of universe, however, plot armor would definitely be the answer.
