[Performance Direction] (Lead and backing vocals: Seamoons-inspired mechanical singing with air-driven rubber vocal cords. Clear Japanese consonants, rounded buzzing vowels, elastic pitch slides and slight settling wobble. Parenthesized lyric phrases are backing echoes in the same voice. Exaggerate mouth-like oo-to-wah resonance on sustained vowels and wa-wa responses. Matching instrumental replies fill vocal gaps. No vocoder.) [Intro] (Waa wa-wa waa, wa-wa-waa!)
