Though Hayate is an orphan, she gets an allowance from her father's friend and lives with the Wolkenritter, whom she tells civilians are her relatives. Though she is their mistress, she sees herself only as their friend .
The Wolkenritter initially comply, but after a few months, they realize that the Book of Darkness is sapping her mana to fill its pages, and that if they do not fill it with the mana of others, it will continue stealing Hayate's mana and potentially kill her. The Wolkenritter decide to keep this secret from Hayate, knowing that she would not approve fighting for her sake, and decide not to kill anyone to get it. The Wolkenritter, especially Vita, are determined to save Hayate even if it means going against her wishes.
However, what the Time-Space Administration Bureau knows that they do not is that the Book of Darkness, once completed, may stop sapping her Linker Core for pages, but that does not mean that it will stop hurting her or undo its damage. In fact, the master of the Book dies upon its completion. Nanoha and Fate try to tell the Wolkenritter about what will happen to Hayate, but their confrontation is cut short by both the interference of two masked men and the completion of the Book of Darkness with the Linker Cores of the Wolkenritter themselves.Hayate screams in horror for all of this to stop and is taken over by the will of the Book of Darkness.
Absorbing the knowledge of the Book of Darkness, she realizes the truth of everything that has been going on behind her back, the innocence of Nanoha and Fate and the sadness of the Wolkenritter. That cannot be forgotten, Hayate asserts. She is the mistress, and the Book has to do what she says. She takes control of her body again so that Nanoha can disable it and gives the Book a new name, "Reinforce". Hayate reprograms the entire Book, but something still remains inside that wants to continue its path of destruction and pain.
