Episode Title:
Lost Memories.
Episode Description:
Ryōta pierces Saori through the heart as she kills him. Knowing she will die from her wound if left untreated, she is forced to use her ability of time-manipulation to go back to the time before Ryōta and Neko were killed, causing Saori to exhaust her magic. As a side effect of going back in time, Ryōta forgets the fact that Neko is Kuroneko. Saori is bound to a pipe, however, she tricks them into letting her go. Seeing her as useless, the lab triggers the beacon on her harness to eject, causing her entire body to melt. An amoeba-like creature moving across the floor revolts Ryōta, causing him to stomp on it. Hurrying back to the observatory after managing to get the pills, they find Kazumi there with Kana, both of which are only barely sustaining themselves. With the witches' lives secure for now, Neko goes with Ryōta and the class to the ocean, where Neko breaks into tears as though she wanted to see the view there for many years. Later, Neko gives Ryōta a communication device and a container with a fertilized alien egg, which were entrusted to her by Akane, a researcher who's responsible for the escaped witches. Ryōta bathes in a hot spring near the observatory when Kazumi and Neko come in, much to his embarrassment. Kazumi also uses her hacking skills to transfer into Ryōta's class, much as she did for Neko. Meanwhile, Chisato Ichijiku, the chief professor of the lab, is lectured by the higher-ups of the organization who stress on the danger of having witches roam freely. Shortly afterward, another transfer student named Kotori Takatori arrives at the observatory and asks to join the astronomy club as well.
