Calc.

The song 'Calc.' by VOCALOID delves into the themes of fate, love, and the inevitable sadness that accompanies them. The lyrics suggest a sense of resignation to destiny, with lines like 'Sureちがいは けっきょく運命で' (Differences are ultimately fate) and 'すべては筋書き通りだって' (Everything is according to the script). This deterministic view is juxtaposed with the singer's struggle to cope with sadness, indicating a lack of strength to mask their sorrow.

The song also explores the sacrifices and contradictions that come with finding answers in life. The lyrics 'はじきだした答えのすべてが ひとつふたつ犠牲ともなって' (All the answers I derived came with one or two sacrifices) and 'ひとつふたつ矛盾ともなって' (One or two contradictions) highlight the complexities and costs of seeking truth. This journey of understanding often strips away the courage to take the next step, leaving the singer in a state of emotional paralysis.

A recurring motif in the song is the memory of a past love, symbolized by a song once dedicated to the beloved. The lyrics 'いつかきみにささげた歌 いまじゃ悲しいだけの愛の歌' (The song I once dedicated to you is now just a sad love song) reflect the transformation of love into sorrow. The singer wishes for the wind to carry away this sadness back to the summer day they first met, indicating a longing to return to a time of happiness and innocence. The song concludes with a contemplation of freedom from past and future, and whether erasing emotions, particularly love, could bring relief.
