Okay, well, I'm officially disappointed in your relationship with Shoya. It is clear that if they had finished his story at his death, there would have been nothing to show, but somehow I don't have galactic-scale villains and "only you, the chosen ones, can destroy him" with Gintama as a whole.
@shei350: there is not enough parody%) It seems that this is a plot that Gintama was supposed to make a parody of, but it is in a very serious tone. If there had been breaks for the usual funny episodes between the last three arches, maybe it would have been easier.
From beginning to end.
. and I hope they will translate and voice it correctly too
