The Ritual Tome (Village Tome: Sacrifices in Deep Crimson Butterfly) is an old book found in Fatal Frame II: Crimson Butterfly and Fatal Frame II: Deep Crimson Butterfly. The book is one in a set of five tomes about village customs. The Ritual Tome describes the Hidden Ceremony, a second ritual performed separately from the Crimson Sacrifice Ritual to calm the Hellish Abyss.
The Ritual tome is also used to solve the Tome Puzzle in the Master's Room to obtain the Light Key. The key word in the tome is "Kusabi (楔)" and is highlighted red.
Fatal Frame II[]
- "If the ✱ rumbles on a year without the ceremony, a Kusabi is needed.
- A Kusabi is an outsider, made into a Buddha, and offered to the ✱.
- The more they suffer, the greater the calming of the ✱."
Fatal Frame II: Deep Crimson Butterfly[]
- In the years when there is no Crimson Sacrifice, the ✱ grumbles with dissatisfaction, and must be satisfied with a Kusabi.
- A Kusabi must be one from outside Minakami Village, and must be prepared in a ritual before being presented to the ✱.
- The more suffering a Kusabi endures, the greater the extent to which the ✱ is appeased.
