Donna mirai mo ima no futari wo
Ubau koto nado dekinai

Moshimo ai wo osorenu mono ga
Togameru no da to shitemo

Konna ni utsukushii me de
Unazuku kimi ga iru
Inochi kakete mamoru koto wo
Chikau no sa

Because it's unbreakable
Tatoe konya kono yoru ga kuzureyou to
Futari no tsuyoi omoi dake wa
Dare ni mo kowasenai

Kodoku na machi sa itsu kara koko ni?
Umareta toki kara to you said

Ikutsu no ai ga tsumi to yobarete
Chigirete shimatta darou

Dou shita no ka wa iwazu ni
Urunda sono hitomi
Mou doko made ittemo ii
Tomaranai

Because it's unbreakable
Tatoe ashita kono sekai mayoou to mo
Futari wo musubu kizuna dake wa
Dare ni mo kowasenai

Konna ni utsukushii me de
Unazuku kimi ga iru
Inochi kakete mamoru koto wo
Chikau no sa

Because it's unbreakable
Tatoe konya kono yoru ga kuzureyou to
Futari no tsuyoi omoi dake wa
Dare ni mo kowasenai

Unbreakable (unbreakable ima)
Tatoe ashita kono sekai mayoou to mo
Futari wo musubu kizuna dake wa (ah kizuna dake wa)
Dare ni mo kowasenai

Kono mama dakishimete iyou
Kowareru kurai
