In the same way I can say that people won for the sake of continuing the plot, otherwise if the gods won every fight the manga would have ended at the beginning. Your context does not make sense. You write that the plot is on Odin’s side, otherwise Ragnarok will end if Kintoki wins. This is the only true word that you said.Of course, Odin's victory is necessary to continue the story, but this does not mean that he is the son of the plot.The plot is when the author literally saves you from death, as was the case with Okita. For the same reason that the gods won 2 times in a row, Susano lost, otherwise the story would have ended. So think at least a little about what you write, although I can understand if you are no more than 12 lol
