What amazing way to animate a double battle - with the action flinging back and forth between Lügner x Fern and Linie x Stark, with the first becoming fireworks for the second, only to deliver the finishing blow of both fights.

Relevant detail, on the names of the demons:

• Draht (dead) - German for “wire”. Remember his power?
• Lügner - German for “liar”. It’s what he does - he lies to humans.
• Linie - German for “line”. It includes line of battle; she’s basically like multiple infantry in a single demon.
• Aura - mostly the Latin word for “air” or “wind”, but also associated with the esoteric belief of some energy around your body. If you think on how anime/manga usually represents qi, mana etc., it is a lot like aura, and that she basically measures that “aura” of hers vs. her opponent’s.
