I've been thinking about how Naruto Shippuden sort of aligns with that Ergo Proxy, Death Note, Lain, 2deep 2edgy vibes.
The akatsuki are very much with the 2edgy stuff, Pain and Konan remind me a lot of Vincent and Re-L and I wonder if Kishimoto was influenced by Ergo Proxy. The Infinite Tsukuyomi is kind of like Lain or Evangelion, yeah Naruto's got dark shit man.
