“ Angela, you have to feel the same sorrow as mine... No. You have to feel even worse than that. You took Angelica from me--she meant the world to me. I sat on my hands as I watched people I knew die, and I even killed my own best friend with these shadowed gloves, just for this moment. All for this moment... I've been suppressing my emotions, forcing this pained smile. ”
–Roland to Angela

The Black Silence (검은침묵, Geom-eunchimmug) was a Color Fixer, known for its gloves that, along with storing all its weapons, muffled all sound around its surroundings save for its weapons cutting through the air. Originally a title held by Angelica, her gloves were used by Roland after her death at the hands of The Pianist.Donning his Perception-blocking mask, he went on a rampage, killing Fixers, Syndicates, and anybody who seemed suspicious enough in a vain effort to find out the culprit behind the incident. He was eventually exposed, however, losing his status and demoted to Grade 9, with the only option left for him being cooperating with Iori to infiltrate the Library. After defeating the Argalia, he turns his blade on Angela, revealing to have been waiting until she was human to enact his revenge on her for killing his wife.
