永遠の繭期が終わり
あたしたちは夢から目覚める
御伽噺は結末を迎えた
現実の世界へと帰ろう
どれだけ辛いことがあっても
それをすべて受け入れるの
夢の中で夢を見てはいけない
現実にこそ夢の花は咲く
 
永遠の繭期の終わりに
美しく咲いた花は散る
永遠の繭期の終わりに
メメントモリの歌を歌おう
永遠の繭期の終わりに
少女の宴は終止符を打つ
永遠の繭期の終わりに
グランギニョルの幕は閉じる
 
目覚めよ　甘き死よ来たれり
 
Uh......

Eien no mayuki ga owari 
Atashitachi wa yume kara mezameru 
Otogibanashi wa ketsumatsu wo mukaeta
Genjitsu no sekai e to kaerou 
Dore dake tsurai koto ga atte mo
Sore wo subete ukeireru no 
Yume no naka de yume wo mite wa ikenai 
Genjitsu ni koso yume no hana wa saku 
 
Eien no mayuki no owari ni 
Utsukushiku saita hana wa chiru 
Eien no mayuki no owari ni 
MEMENTO MORI no uta wo utaou 
Eien no mayuki no owari ni 
Shoujo no utage wa shuushifu wo utsu 
Eien no mayuki no owari ni 
GURAN GINYORU no maku wa tojiru 
 
Mezame yo amaki shi yo kitareri

The eternal chrysalis period has ended
We have awoken from a dream
Our fairy-tales have reached their conclusion
And we return to the world of reality
No matter how painful it is
We must accept it all 
Do not dream within a dream
In reality too, the flowers of dreams bloom
 
With the end of the eternal chrysalis period
Flowers who have bloomed beautifully dissipate
With the end of the eternal chrysalis period
Let us sing a song of memento mori
With the end of the eternal chrysalis period
The girls' banquet comes to an end
With the end of the eternal chrysalis period
The curtains of the Grand Guignol fall
 
Awaken, for a sweet death approaches
 
Oo......
