"A Visitor: A Burning Field of Snow"

Whilst on patrol in the snow, Kanata and Kureha stumble upon an unconscious Roman soldier. Noël, who had just finished rebuilding the Takemikazuchi, seems to recognize her and asks to look over her. She wakes up the next day and introduces herself as Aisha Aldola, though she is unable to speak or even understand Helvetian. Kanata and Noël spend some time with her, and Kanata is surprised and overjoyed she knows how to play "Amazing Grace". Later, Naomi and Yumina arrive, informing them that Helvetian armies are heading towards the fortress. Yumina acts as a translator for Aisha, who says that she wants to see the Angel Fossil (the one Kanata saw underwater in the first episode), the remains of the "Angel of the Apocalypse" that brought upon judgment to the world of the distant past. Just then the 9th Independent Mobile Division, under Colonel Hopkins, the infamous "Demon of Vingt," starts to arrive at the fortress, and Noel becomes particularly scared. Filicia decides to hide Noël and Aisha from Hopkins' contingent, who takes over the fortress. However, their position was given away when Aisha recognizes Noël as the The Witch of Helvetia, the Invisible Reaper, causing her to scream at the bad memories and run away. At the same time, the fortress gets a call that a massive Roman army contingent has been spotted advancing in No Man's Land towards the border of Helvetia at Seize.
