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.
Just as naïve as your mother,
and it's gotten you both killed, fool!
!سذاجتك وسذاجة والدتك قاتلة أيها الأحمق
¡Tu madre y tú
son unos ingenuos, idiotas!
¡Tanto tu madre como tú
sois unos ingenuos, idiotas!
Ça finira par te coûter la vie
comme à ta mère, crétin !
Quella ingenuità è stata fatale
 anche a tua madre, sciocco!
Essa ingenuidade em você
e sua mãe é fatal! Idiota!
Эта ваша с матерью
наивность — ваш рок, глупцы!
