Black Suited Men

This group of four black suited men are unnamed characters in Seraph of the End. They were observed awaiting some development by Guren Ichinose and Shinya Hīragi. Appearing in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen manga, the chains they could use were of little help when they cam under attack from a vampire.

Appearance
Their appearance resembled that of Hyakuya Sect assassins. All had a similar hair style, dark in coloration, short in length and slicked back. One member’s hair was lighter in coloration. Wearing identical clothing, it was a white collared shirt with a dark tie. This was just about visible under a prominent long black, long sleeved coat, the length of which went down to their shins.

Personality
Standing silently, three members stood with their hands held behind their backs in a relaxed manner. While appearing somewhat nervous at a potential threat, they reacted by attacking the more powerful foe.

History
Considering the context, at some point they became members of the Hyakuya Sect. Remarkably, they could generate and effectively used chains, a very rare weapon system and one almost exclusively used by exceptionally powerful individuals.

Story
At around 1:45am they were stationed near the Hikarigaoka park's tennis court, waiting for a event planned for 2am that night. Having noticing something, where communications took place between them, one member's head is struck off. Two members regard this, before a vampire drops into their midst.

Damning it, chains emerged from their backs which were directed at the vampire. After these jabbed into the ground all at once, they see the vampire leap backwards towards them. One members head is seized, and essentially pulled off. Cursing her, another member’s chain fired at her is avoided. A third man’s head is gripped, and yanked, where the final one finds the vampire opening her mouth at him. He is the only one not decapitated, falling after being bitten instead.

Weapons

 * Chains - able to produce and wield at least two at once from their backs, the spiked tips could be used to strike targets from a distance.
