innocent arroganceBiSH

BiSH, the girl group that disbanded in 2023 to much regret, performed the opening theme for the anime Heavenly Delusion, titled “innocent arrogance.” The song pairs an intense, heavy bass sound with lyrics about hope and courage.

You might feel there’s a gap between the music and the words.

It makes sense if you think of the fierce sound as expressing the anime’s dark world, while the lyrics represent the protagonist who refuses to lose hope within it.

The anime Arknights [Prelude to Dawn], which aired in the fall of 2022, featured “BE ME” as its ending theme.

It’s an original song written by the new-generation artist Doul, with a vibe reminiscent of an all-English jazz track.

Its wet, not-too-bright tone matched the series’ worldview.

The lyrics, which sing about the transience of life and happiness, also seem to reflect the anime’s story.
