Tsugumi was abducted as she was returning to the apartment and taken to Nachtigal. Shiginuma Takashi tells Tsugumi that he will take advantage of her powers and have her bear his child to succeed him. Meanwhile, having ascertained that the fake cursed tomes are being made in Nachtigal, Rui and his Kagutsuchi companions infiltrate the grand building in order to put a stop to this. In the midst of the confusion, Hayato, Hisui, and the others make their way into Nachtigal to search for Tsugumi. During the search, Hisui comes face to face with Professor Mozuyama, who has conducted numerous human experiments.
To defy me after wounding my 
eye and leaving me like this!
!بأن تعصيني بعد جرحك لعيني وتركي هكذا
Du widersetzt dich mir, nachdem du mir
mein Auge genommen und mich verraten hast.
¡Me desafías tras lastimarme
el ojo y dejarme así!
¡Me desafías tras herirme
el ojo y dejarme así!
C’est toi qui m’as rendu
borgne et invalide,
Sfidarmi dopo avermi 
ferito l'occhio e lasciato così!
Me desafiar depois de ferir
meu olho e me deixar assim!
Сначала ранил мой глаз,
оставив меня таким, а теперь бунтуешь!
