Lilith in “Administer and Third Selection”

You must make a choice, Arata Kasuga. I implore you, command this grimoire to destroy this farcical world you created, in which case, I will allow you to live, and you can spend the rest of your days in peace. The caveat being that I will destroy the grimoire and your memories of Hijiri Kasuga will be decimated. If you do not hand over the grimoire, I'll be forced to end your life. You wished this world into existence, and only can send it back into oblivion.
