Owaranai yoru o

Karamiau shita wa hitsuyou ijou no ai
Guuzou kairaku zecchou o anata ni ageyou

Gensou shihai ni yureru
Anata no oku ni tsuita uso
Guuzou kairaku no naka e
Hora kimi no karada ga shitteru

Nademawasu yubi de anata o shizumetai
Inbi na namida o nagashite nakeba ii

Gensou shihai ni yureru
Shikai ga nureru hodo high ni
Guuzou kairaku no naka e
Aa kimi o tabechau yo
