Astolfo is a Rider class servant in the Fate franchise, first widely known through Fate/Apocrypha, where the cheerful pink haired paladin became a breakout fan favourite far beyond the series. The Italian phrase meaning Astolfo is our god grew in Italian anime communities as hyperbolic praise, turning admiration into a mock religious chant. Shared as edits and soundboard clips, it spread because Astolfo's popularity mixes genuine affection with irony about his cult like following, and it remains a shorthand for devoted Fate fandom humour.
