The demonic tome Alice Margatroid used as a weapon in the Extra Stage of Touhou Mystic Square. Using the book helps bring Alice to her full potential, but due to her cowardly inner nature and her fear of the implications if she lost a fight at full power, Alice normally keeps the tome wrapped in two padlocked leather bands, only passively tapping its power in small bits during a battle. When the grimoire is open and being actively used, Alice's power is that of an Extra Stage boss, on par with the likes of Flandre Scarlet and Fujiwara no Mokou
