If Madara was the protagonist of his own show, this would be the opening. Hands down. No question.
His innocent smile at the beginning too like OMG.
This song has such an upbeat sound to it, and what do we see? Madara, slaughtering anyone he sees. Funny, right?
And then there's the shinobi writing in blood that shows what a lot of characters had been through. How deep is that? I feel like that's what Madara predicted though. Full of death and despair.
When they show the shot where Madara looks through the hole in the leaf, that's him seeing nothing but tragedy and sorrow. The way Madara sees the world compared to how someone like Naruto sees it just hits me deep.
Overall ranking, 10/10.
