Diabla literally translates to "she-devil". It's a powerful word that captures the song's central theme of female empowerment and defiance.
In the lyrics, Kali Uchis describes how she was cast as the villain in someone else's story: "la diabla de tu historia" (the she-devil of your story). Instead of fighting the label, she powerfully reclaims it, declaring, "pues diabla es lo que soy" (well, a she-devil is what I am), turning an insult into a symbol of her strength and independence.
Kali Uchis kicks off this song with a question: what would you say to the people who didn't believe in you? Her answer is simple and devastating: "A mí me gusta que vean lo feliz que soy sin ellos" [I like them to see how happy I am without them]. This is a song for anyone who has left a bad situation and is finally thriving. She describes a past where she was in a nightmare, crying herself to sleep and putting up with mistreatment that hurt like bullets. She even says she was seen as "la diabla de tu historia" [the devil of your story].
But that's all in the past. The chorus is a powerful declaration of freedom and self-worth. She sings, "Pues eso ya pasó, y esa ya no soy yo" [Well that's over, and that's not me anymore]. She has found her own wings and knows she deserves better. The best part is how her happiness becomes the ultimate revenge. She tells her ex, "Nunca vas a poder cortar mis alas / Y eso es lo que te mata" [You will never be able to cut my wings / And that's what kills you]. It's a perfect kiss-off, celebrating her newfound joy and peace.
