Father Otto, the priest who wants to go to heaven! Kiana the End descends upon the Domination Theater! And Dark Zaki descends upon the world of collapse!

Ten thousand years ago, I witnessed the destruction of a civilization, the shattering of memories, and the arrival of an end. At that time, I was powerless to stop it.

Fifty thousand years ago, I felt a familiar civilization, familiar things, and familiar people, but the memories that traveled through time were not in my mind. I watched as the end destroyed civilization once again, but I suddenly regretted it.

And now, the power to save everything, all the memories of the past, are within me. This time, I don't want to lose them again, nor can I lose them. I will grant your wishes and make this world beautiful again.

Sing joyfully, all things in the world, to welcome the death of your god, who will bring boundless beauty to this world. What, "you" refuse? No, no, no, you have no reason to refuse any of this, nor is there any room for negotiation.
