Michael Gedoin, lost in his admiration and adoration for Lucifer, takes further action to ensure the success of his Elixir research. He devises a plan separating Rin and his team – leaving each member to fend for themselves. Although Rin faces off against a giant, grotesque Zombie in the underground laboratory's container, he hesitates to use his sword against it when he realizes the Zombie is a human corpse possessed by a demon. Yukio, Suguro, Shiemi and Konekomaru each must face off against their demons in the laboratory alone...
No wonder we can't kill them no matter
how many times we destroy their brain stems!
لا عجب أنّنا لا نستطيع قتلهم مهما
!حاولنا تدمير جذوع أدمغتهم
Und egal, wie oft man sein Stammhirn zerstört,
man kann ihn nicht besiegen!
Por eso no podíamos derrotarlos.
Con razón no podíamos derrotarlos.
Voilà pourquoi ils se relèvent,
même le tronc cérébral détruit…
Ecco perché non riuscivamo ad annientarli, 
anche colpendoli più volte al cervello!
Por isso que não podemos matá-lo,
nem mesmo destruindo seu tronco cerebral!
То-то наставник их убить не мог,
сколько бы мозг ни простреливал!
