- —Nacht's intro quote, Akatsuki no Kiseki
Nacht is an average young man sporting white hair with light red eyes. He wears a patterned azure jacket, a crimson handbag around his right waist, khaki pants up below his knees and dark brown boots.
At the beginning, Nacht appears to like an ordinary person when referring to prefer do things normally one at a time. But after being paired with Chloe who prefers to push the envelope, Nacht always state in disagreement for her over-achievement mindset.
A man with an unknown nationality, Nacht Weiss strives to stray from his tragic past as a former Jaeger member to restart for a normal life as much as possible. Having originally intended to just take up a steady stream of small jobs upon becoming a Bracer, those plans get thrown out the window once he is paired up with Chloe Barnett for his partner, whose personality happens to be diametrically opposed to his. He is highly proficient in combat techniques while adapting to his surroundings around fighting with an Orbal Bayonette, whilst possessing knowledge of guerilla warfare from his usage of Orbal landmines.
