Loud vocal-synth rock with djent claws and metalcore circuitry, 馬P fires up Unstained — meaning “free from stain” or “unblemished” — like a chrome-plated riff engine running on existential voltage. The track uses Miyamai Moca / 宮舞モカ, a Synthesizer V AI voice database based on voice actress Mayu Mineda / 峯田茉優, giving the song a cool but powerful synthetic vocal bite rather than a traditional human-fronted band feel. Tiny nerd correction for the pit crew: Miyamai Moca is vocal-synth royalty, but not technically a VOCALOID.
