My top animes do change every once in a while but I think right now these are my top 5:
1: Fate/Stay Night Unlimited Blade Works
2: Fullmetal Alchemist: Brotherhood
3: BNA
4: Jujutsu Kaisen
5: either Fate/Grand Order Absolute Demonic Front - Babylonia or Gundam Build Divers Re:Rise (im still deciding on number 5)
