Meeting Mako and Chisato who have arrived at the observatory are demanding to hand over #1107 who's in fact—Kotori. Ryota distracts them for Hatsuna to jump on Mako from behind, but can't figure out which button to push on Mako's harness having her to slice Hatsuna. Wanting an explanation why they have to be killed, Chisato states the B-rank witches are unreasonable to live. He orders Mako to kill Neko, but Ryota push her away and takes the hit from Mako's magic. Losing consciousness, Nanami appears in astral form to Ryota informing that Neko used to be an S-rank witch stronger than Mako, the way to regain her power is by pressing the top button of her harness but it's a high risk; then Ryota dies. With the girls distressed and defenseless, Mako about to finish them off, but then a group of black individuals arrive who have neutralized Mako's magic. Following the device's signal that Ryota turned on earlier. Yet, Chisato escapes using Mako's teleportation taking Kotori along. Hatsuna had recovered and using her ability to heal; with Neko and Kazumi giving heart aid, they revive Ryota. Hatsuna melts in the process however. Miki and the individuals introduce themselves as Hexenjagd, a group resisting the lab, stating the witches still has to die because the amoebas "drasils" inside them - the witches' true form - will eventually hatch and devour their bodies into monsters. Moreover, Kotori has an entity called the "Grane" that can destroy all humanity. They tried to capture Kotori once, but failed, causing the witches' escape and losing a comrade (Akane). Kotori awakens before Chisato, calling her Rena. Rena was Chisato's younger sister whom believed was the only life meaningful to him until she died of 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 somehow. Not giving up, despite the revelation, Kazumi hacks in the lab's database locating Chisato's whereabouts near the lake, having Hexenjagd to take them along. Kotori asks Chisato what he feels for Mako, though he answers that she merely someone important for his plan. Suddenly, Kotori's harness hatches a light "Ain Soph Aur" into the Earth's atmosphere that begins covering the planet.
