I finally made a cover using Shiki Taigen! He wasn't easy to work with, but fortunately I was able to switch between resamplers to get the best results by using OpenUTAU. Once the vocals were made, mixing them was surprisingly easy.

Despite how different Shiki sounds to Miku's voice in the original, I thought this would be a good song to have him sing. Something about his roughness makes it feel almost endearing, I guess.
