sentences:  The demon twins invite the group to their domain and when they reach them, the girls are able to defeat Mephis and Pheles, however even though Rei, Sen, and Nanana hadn't agreed to the Executor contracts in this timeline yet (Kokoro having agreed months before) the contract transferred over to this timeline as well (which was the only reason they were even able to fight the twins in the first place) and thus the twins mind control the girls and try force them to fight each other to the death again - however Anamnesis and Mirai interfere (Mirai stating that she's the only one allowed to bully Rei) and transport the girls into their souls, and help them girls overcome their greatest insecurities, which is where the twins had placed the contracts within their souls.Rei gets over the despair that she was the one who killed her sister, Kokoro deals with the despair of Anamnesis taking the souls of her boyfriend and baby, Sen deals with the grief of Mirai killing her mother, and Nanana accepts the fact that she is actually Nanami Ataraxia and not Nanana, and this breaks the contract for the girls.Shocked that the contracts no longer have any effect, Mephis and Pheles merge together to form Mephistopheles but are killed by the group.
