A Cruel Angel's Thesis

A Cruel Angel's Thesis by Evangelion is a J-pop song in the original key of C minor. It was composed by Hidetoshi Sato and performed by Yoko Takahashi. The song serves as the opening theme for the anime series Neon Genesis Evangelion. A curious fact is that the lyrics, written by Neko Oikawa, were intentionally made vague to allow multiple interpretations. The melody is energetic and catchy, combining elements of pop and rock genres with strong vocals.
