Episode 9: Atomis' Double Face (Part 2)

Even after having been taken captive, Teresa continues to stalemate Yuu who quickly finds that Teresa's antipathy toward him has soured her soma. Undaunted by this setback, Aoi proceeds with her mirage as a house-guest who charges Sasha a mortal volition for her brother that ignites a divergent concourse with Mafuyu who does not like that Sasha has forgotten whose residence it is when Hana hauling in the badly damaged Ekaterina prompts Aoi to explain her prologue with her twin brother Yuu but is unable to maintain the mirage when asked the relationship Mafuyu has with Sasha upon detecting the wound from Teresa's arrow attack. Teresa now emancipated, all that remains is to evacuate her -- a task easier said than done with the psychotic Aoi wielding oxygen as a weapon when the floor underneath gives way. A soma recharge from Mafuyu and some metallurgy later, Sasha fights Aoi to a stalemate while Ekaterina intercedes for Mafuyu after she restores Anastasia with Hana's soma; the ultimate irony of Sasha finishing off Aoi is that even though it did not change the situation for the better, Sasha begins to comprehend the rationale behind Mafuyu's plea for clemency when he realizes that Aoi and Yuu supporting each other has many parallels to his prologue with Olja.
