I can't stop thinking that maybe the 4 knights of the apocalypse are Percival's group, Nakaba said it wouldn't make sense to make the protagonist of 4KOTA one of the children of sins, so it's likely that Tristan isn't one of the 4 knights of the apocalypse, for this would contradict his statement. The description is pretty obvious if you think about it, Nakaba should make a mystery harder to uncover, saying that one of the knights has evil and sanctity in their eyes would make everyone directly connect to Tristan, and that's the biggest problem, it's a very obvious tip, what if Nakaba is giving us false leads? Perhaps nothing is as we hope and the 4 horsemen of the apocalypse are percival, donny, nasiens, and anne, Donny looks quite similar physically to the knight of plague, and the question of evil and sanctity in the eyes may be because Donny has a certain duality, while he is a good person he also hides a side a bit like a rogue, the war could be Nasiens, while the knight with golden magic could be Anne, as in Arthurian legends angearde was called the knight of the golden hand or something similar , maybe we have a team skip, and everyone gets older, except for Percival who is maybe immortal, or else everyone else's appearance is fake and it's just something to confuse us, as sin posters were fake in season 1 of Nanatsu.
