Hard Afterglow
Hard Afterglow is the propulsion system on Valvrave units in the Valvrave franchise. Together with the Yatagarasu emblem, it contributes to the Valvraves’ organic, almost living appearance. The series was praised for seamless 2D and 3D integration and for making CG look natural in mecha combat; the Hard Afterglow and fluid motion reinforced the biomechanical design philosophy.
