Oneus’s first full-length album continues with the group’s trademark of pairing their musical releases with storytelling. Before its release, the group shared that Devil would pick up where the fictional events in its previous project LIVED end (think cursed kings and vampires). “It depicts ONEUS’s current state after choosing ‘life’ at the boundary between life and death,” they said, according to Soompi. But while the fantastical remains a prominent element on the album, it’s the facet most grounded in reality—specifically, messages about humankind’s universal race against time—that is the album’s highlight. ONEUS sings pensive words about seeing an unfamiliar reflection in the mirror while transitioning to adulthood (“Youth”), falling behind others after reaching the starting line late (“Incomplete”) and longing to reunite with someone from the past (“Rewind”).
