Past ~Memories Leading to Tomorrow~.Yami starts telling Rito about her past, explaining how she was created by a woman named Tearju Lunatique using her own cells, therefore Yami is effectively a clone of Tearju and sees her as her mother. However, Tearju was taken away from Yami by the association that had asked to create Yami. They forced Yami to follow the path of darkness and trained her to be a weapon. She doesn't know what happened to Tearju and also notes that the society was destroyed when the Devilukes unified the universe. Rito demands revenge, which confuses Yami given that Rito is her target. Yet somehow, Yami feels safe with Rito as she leans towards him. During the conversation, Momo tries to spy on Yami but is caught by Mikan. Momo convinces Mikan of the necessity to spy on them claiming that Rito may do inappropriate acts with Yami in his sleep. Mikan reluctantly tags along, but stops and grabs Momo's tail, making Momo scream for help. The effects of Lala's invention soon wears off. Rito praises being detached from Yami, but Yami feels insulted and knocks him down. She snuggles close to him for the rest of the night. The next day in school, everyone is Rito's class is surprised to see a new assistant who Rito recognizes as Tearju. While Lala and friends discuss Tearju, Oshizu asks Rito to come with her. Mikado tells Rito she and Oshizu brought Tearju to earth during her investigation. She found a photo of Tearju and was able to trace her whereabouts. Meanwhile, Momo tells Yami to meet Tearju but Yami does not respond. Rito finds Tearju in the hallway and asks her to meet Yami. Tearju hesitates, blaming herself for abandoning Yami. The principal starts chasing after Tearju, making both of them run. Lala finds Rito and Tearju running and offers them help. She teleports them behind the bushes partly naked. Yami, sitting on a nearby bench, knocks out Rito, catching Tearju's attention. Tearju looks at Yami and calls her "Eve".
