Splatoon - Final Boss (Squid Sisters Ver.) [FM/Genesis Mix]

Whispers unfold beneath trembling skies, where emotion flows like water through broken glass. Every color breathes, dissolving in the silent pulse of memory and desire. The world vibrates with unfinished feelings, fragile yet infinite, resonating through veins of light and stone. In the stillness between collapse and grace, everything cries, and everything learns to listen.
