Amy: This is honestly one of my favorite opening songs in the entire Naruto Series. I think it's actually about both Itachi and Kabuto, but it was easier to just focus on Itachi, who is one of my favorite characters in the series.
The clips are from Naruto and Naruto Shippuden The song is Tsuki no Ookisa (The Size of the Moon) by Nogizaka46 from Naruto Shippuden. Translation by me. :)
