Asterisk was recorded by Japanese rock band Orange Range and used as the first opening theme for the Bleach anime, covering its early episodes in 2004 and 2005. The series adapts Tite Kubo's manga about Ichigo Kurosaki, and the song's mix of rock, rap and pop became closely tied to its identity. Clips of the intro later spread on soundboards and in edits alongside other anime opening themes like Giorno's Theme, because nine seconds is enough to trigger instant recognition for fans.
