Guren no Yumiya is the first opening theme of the anime Attack on Titan, originally performed in Japanese by Linked Horizon for the series that began in 2013. This clip uses a Portuguese-language cover, credited to The Kira Justice, translating its rallying chorus for Brazilian and Portuguese-speaking fans. The phrase about the hour arriving and going on the attack became a shorthand for charging into a challenge, and short clips of it circulate in anime edits, gaming montages and hype videos because the original opening remains one of the most recognisable anime themes.
