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.
Why are you always getting 
in my way like this?!

Pourquoi t’es toujours
en travers de mon chemin ?
Perché mi metti sempre

Por que sempre me atrapalha assim?
Почему ты всегда встаёшь у меня на пути?
