Goosebumps can be triggered by all sorts of things, and for those unfamiliar with the term, it's that feeling of the hair raising on your skin and in some ways presents itself as a rush in your body.
My most notable goosebumps moment in anime, is in Fire Force Episode 23 at the very end of the episode where Captain Burns says to Shinra "Come at Me".
What are your anime goosebumps moments?
