Who is MEMENTOVANITAS?
MEMENTOVANITAS (メーメントヴァニタス) is a VSinger of RIOT MUSIC / 無原唱レコード, and the Supreme Leader of the “Secret Society Mocchalera”. Her voice is said to charm anyone who hears it. She refers to herself with the royal “朕”, wears a plague-doctor crow mask on her hat, loves movies and staying home — and her fans, the faithful “忠僕”, adore every bit of it. Her motifs — the key and the eye, the hourglass, the candle and the skull — come from vanitas still-life paintings, and so does this archive.
