Lyrics:

Dare mo hairenu
Daiya no kokoro
Tsumetai watashi no
Kokoro no naka ni wa

Donna tenshi mo
Akogare sasayaki mo
Otoko no ainado
Todoki wa shinai
Todoki wa shinai

English Translation
No one can enter
This precious cold
Diamond heart
Of mine

Not an angel
Nor whispers of desire
Nor the love of any man
Can ever reach my heart
Can ever reach my heart
