生きて出た者は一人もいない、監獄塔。
其の名はシャトー・ディフ。
この世に在りながら「地獄」とさえ称されしイフの塔。許されざる大罪を犯した者どもを収監する、死の牢獄。　
人は言う。地上の苦しみのすべてが其処に集う、と。
人は言う。怒り、嘆き、哀しむ声が絶えず響く、と。
人は言う。囚われたが最後、脱出など不可能だ、と。

故に、此処を生きて出た者がもしもあれば───
その者は、無限の怨嗟を背負う事になろう。
ヒトでありながらヒトではないモノになるだろう。
人間性のことごとくを超克した、
暗黒の鬼が如き者が顕れてしまうに違いない。

「そうだ！　それこそがオレだ！
　地獄に堕ちて、地獄を喰らって生き延びた者！
　他の誰でもないオレだけが！
　恩讐の彼方より顕れ出でて！
　復讐を───この手で、成し遂げるのだ───」

A prison tower, from which no one has escaped alive.
Its True Name is the Château d'If.
Synonymous with hell itself, the tower holds the most unforgivable of criminals.
People say the torments of this world are gathered there.
People say it constantly echoes with voices of anger, grief, and sadness.
People say imprisonment there is the end, and that there is no escape.

And so, if anyone ever escaped this place alive...
Then they would be burdened with limitless resentment.
They would likely be human...and yet inhuman at the same time.
Doubtlessly having overcome their humanity, only to be possessed by a dark demon.

"Yes! That's me, all right!
Someone cast into hell and devoured by it, who survived nevertheless!
None but I have done so!
I have gone beyond love and hate!
Vengeance... With these hands, I shall have my vengeance!"
