Accessible from a sparkle point in Nier's house after Grimoire Weiss joins, this DLC sends Nier into the diary of his late wife or mother. Inside is a white room with a door. Beyond it: fourteen challenge maps spread across three progressively unlocked doors, each filled with powerful Shades. Completing a door unlocks the next; losing inside an active door resets progress on it, but unlocked doors stay open. Rewards include swords Fool's Embrace, Fool's Lament, and spear Fool's Accord, plus two costume sets.
