Ikku Nagae's PPPPU Gaiden Music takes us on a journey through the unknown, where the only law is that of the flesh. The melody of Shingeki no Kyojin's opening theme sets the stage for a relentless pounding, a testament to the power of unbridled passion. As the music swells, so does the intensity, two bodies locked in a dance of survival, their cries of pleasure echoing the battle cries of the Survey Corps.
