Hiraita tobira no saki kara tobidashita
Mon wa kibou ka zetsubou na no ka
Tsukaima no shiji doori ni, fumidashite miyou ka
Koukai wa zettai sasenai

Sa-chiraito o bure-ka- goto kitte
Jamamono wa mukanjou ni koroseba ii
Jirai no ichi, tatakikondara kakedasu n'da
You will never let me down

Kawarihateta watashi o goran
Kore ga mirai no kagi to naru
Hidarime no aza
Kuroi kesshoutai
"Hayaku aitai na. "
To go over the line

This world under ground
Yubi sasareta
This world under ground
Kimi ni toitai
"Can you promise the loyalty to me? "
This world under ground
Yes nara prostrate

Kawarihateta watashi o goran
Kore ga mirai no kagi to naru

To go over the line

Hiraita tobira no saki kara
Tobidashita mon wa kibou ka zetsubou na no ka
Tsukaima no shiji doori ni, fumidashite miyou ka
Koukai wa zettai sasenai

Maichiru hanabira ga yuki ni kawaru
Sono koro ni kidzuku darou
