In addition to rewatching 5 series, I am wating the new season 2's of both Realist Hero and Arifureta.
The newest episode of Realist Hero has them in the meeting rooom talking about a number of items, just like th elight novels... but it skips two items in the light novels to save time.
The first is a minor item, in the light novels, Jeanne notices the bed and comments her sister does the same thing.
More importantly, the second item skipped is when Jeanne asks why he did not sign the Mankind Declarions, in both he does not give an exact answer, but int he light novel, he tells he a story about a similar story from his (our) world, as a sort of warning to her. that was about our Helsinki accords... later in the light novels this is fully addressed and explained why he told it, and why he did not sign the Mankind declaration, and what the loophole was that he could not tell them at this earlier meeting...
