Seikon no Qwaser - 1x08 - 双面のアトミス（前篇）- Followmy.tv

Furious that Shin'ichiro and Elizabeth have decided to search for the »Tsar's Crowning« on Athos's behalf, the Adepts turn their efforts to their recent find: the fraternal twins Yuu and Aoi Kuchiba. While successful in manufacturing Yuu into a psychotic oxygen-wielding Qwaser hostile to Athos, the Adepts find that wielding Aoi as Yuu's Maria Magdalen partner proves to be their undoing when Aoi slays and assimilates Yuu during an initiation rite; while the Adepts compute their next move, Mafuyu's shock of Shin'ichiro as her world history teacher gives way to the divergent concourse between Sasha and Elizabeth at the banquet that night to which Miyuri invites herself along with the student council president Fumika Mitarae. Miyuri and Fumika grappling with their issues obfuscates Hana being abducted as an open challenge to Ekaterina who soon finds that she is no match for Yuu on her own with Anastasia now a scattered pile of corroded copper. Hana's courage and Teresa's ranged cover fire ultimately proves itself Ekaterina's life-saving deus ex machina; unfortunately, Sasha has no idea that Aoi is leading him into the same kind of trap when he replies a love letter that he finds at school day inception.
