|kan1=さあ　悲しい目をしないで
私のために噎び啼いて
水晶の喙で
悪徳の接吻を噛み砕いてご覧
|kan2=沸った紅榴の雫
はらはら零れる
|kan3=自由を讃える声なら
荊棘で絡め封じ籠めよう
その目が象る境界に
私しかいない
|kan4=ねえ　嘆息を吐かないで
私だけが貴女を護れる
|kan5=冥府の窓帷閉めたら
星も月も輝かない
|kan6=撥条仕掛けの時計が
カチカチ死にゆく
|kan7=天宙へ飛ぶための羽根なら
捻り潰して飾りましょう
生まれ変われない貴女は
私だけの小鳥

|rom1=saa kanashii me wo shinaide 
watashi no tame ni musebi naite 
suishou no kuchibashi de 
beeze wo kami kudaite goran
|rom2=tagiritta kouryuu no shizuku 
harahara koboreru
|rom3=jiyuu wo tataeru koe nara 
ibara de karame fuujikome you
sono me ga katadoru sekai ni 
watashi shika inai
|rom4=nee tameiki wo tsukanaide 
watashi dake ga anata wo mamoreru
|rom5=meifu no kaaten shimetara 
hoshi mo tsuki mo kagayakanai
|rom6=zenmai jikake no tokei ga 
kachikachi shi ni yuku
|rom7=sora e tobu tame no hane nara 
hineri tsubushite kazarimashou 
umare kawarenai anata wa 
watashi dake no mono

|eng1=Now, don’t look so sad.
Sob, sing, for my sake.
Chew on the corrupting kiss
With your crystal beak.
|eng2=The boiled pomegranate’s droplets
Rapidly drip down.
|eng3=By twining thorns around you, I’ll shut away
Your voice that sings the praises of freedom.
In the world your eyes resemble
There is no one but me.
|eng4=Hey, please don’t sigh.
Only I can protect you.
|eng5=Once the curtains of hell close,
Neither the stars nor moon will shine.
|eng6=The wind-up watch
Ticks as it dies.
|eng7=I’ll decorate your wings to fly with
By twisting and crushing them.
You, who cannot be reborn, are
A songbird that belongs only to me.
