Witch Hunt.Mako and Chisato arrive at the observatory where they demand to hand over #1107 who's in fact—Kotori. Ryōta distracts them for Hatsuna to jump Mako from behind, but can't figure out which button to push on Mako's complex harness to hang her up. Mako retaliates by slicing Hatsuna in half. Wanting an explanation of why they have to be killed, Chisato states the B-rank witches are irrelevant. He orders Mako to kill Neko, but Ryōta pushes her away and takes the hit from Mako's magic. Losing consciousness, Nanami appears in astral form to Ryōta divulging the fact that Neko used to be an S-rank witch stronger than Mako and that the only way to regain her powers is to press the top button of her harness. However, the method is highly risky, after which Ryōta dies. With the girls distressed and defenseless, Mako is about to finish them off, but then the mysterious group of black-clothed individuals arrives who neutralizes Mako's magic following the device's signal that Ryōta turned on earlier. Nonetheless, Chisato escapes using Mako's teleportation taking Kotori along with them. Hatsuna recuperates herself and using her ability to heal with Neko and Kazumi performing CPR, they revive Ryōta; Hatsuna melts in the process. Miki and the individuals introduce themselves as Hexenjagd, a group resisting the lab, stating the witches still have to die because the "Drasils" inside them - the witches' true form - will eventually hatch and devour their bodies, giving birth to monsters. Moreover, Kotori has an entity called the Grane that can destroy all humanity. Hexenjagd tried to capture Kotori once but failed, though it was during this incident that they lost their comrade (Akane) and led to the other witches being able to escape. Kotori awakens before Chisato calling her Rena. Rena was Chisato's younger sister who believed is the only life meaningful to him until she died of an unknown sickness. He tells Kotori how aliens were believed to be the creation of humans on Earth. His efforts to revive Rena's soul within Kotori's body ended in vain. Not giving up, despite the revelation, Kazumi hacks into the lab's database to locate Chisato's whereabouts near the lake and having Hexenjagd to take them along. Kotori asks Chisato what he feels for Mako, though he answers that she is merely someone important for his plan. Suddenly, Kotori's harness gets activated and shoots a light called "Ain Soph Aur" into the Earth's atmosphere that begins covering the planet.
