My Suggestions?

To begin with....

Dust, due to the first fact, that he is a wandering vigilante, and an active killer/hunter of all criminals and illegal organisations over a period of around 6 years. I'm betting that he has at least killed or encountered one of the Black Order during his time doing so, as well as disabling some of their operations, or at least hampering them, as he doubles as a gatherer of information. Plus, his nickname andtitle is already badass.

Valka Cedafalt because, well, firstly, she's a high ranking ANGEL, and a known killer. Secondly, she has literally fought in a warzone with multiple participants, which would garner a lot of attention. Additionally, she undertook a large, full-scale battle of two ANGELS, and won, with the battle being broadcasted among the ANGELS. I'd bet at least one of the Order would have noticed her.

Lastly, Alvadek Xie because of her renowned brutality with victims and her status in LUCIFER. Her name would carry some meaning, as she is known for having escaped Atlas in the freezing winter, but her battle style is quite recognizable, along with her distinct weapon. Her reputation as a merciless killer and a sadistic, bloody torturer might reach the ears of some of the Black Order, which might give her a role in their 'Demonology'.
