Yameii Online’s electronic track "Arifureta" adopts the themes of betrayal and transformation from the Arifureta: From Commonplace to World's Strongest series. The song utilizes a vocaloid, high-energy style to reflect the "edgelord" aesthetic and the protagonist Hajime Nagumo's journey from a weak, betrayed student to a powerful, vengeful survivor.
