Nicolas Brown

Nick, Nico, ニコラス・ブラウン

Nicolas, half of Benriya, possesses exceptional sword skills and presents an intimidating demeanor. Although he's deaf, he communicates mainly through sign language but can also speak in a restricted manner. Along with Worick, Nicolas operates as a hired gun. As an A/0 level Twilight or "tagged" (referring to his dog tags), he is both feared and detested on the streets. Despite his tough exterior, Nicolas harbors a tender spot for Nina and gradually warms up to Alex's presence at the Benriya household.

Spoilers:

It is later mentioned that he is actually the equivalent of a B/5 without his uppers overdose. Nicolas is only able to have the strength of an A/0 by overdosing on uppers. This is why he is considered a "faker."
