There is such a very disturbing record on page 73 of the diary.
The water-soaked paper seemed to have been tortured and it became difficult to keep it in order. The ink rubbed by fingernails made the entire page messy and dirty.
But the text is still legible.
…
Missing Chapter 131.
Yes, Chapter 131.
Those mottled symbols record and convey...
"The light of the past remains
The suffering of the past is here now
The torture of the past will remain forever
You walk in the darkest beginning
You are walking outside the bunker
Only Yara Muth knows the location of the Requiem Gate
