His name was Kravel Mortain. In the underworld, he was more famous by the nickname 'Black Carapace'. Few knew his real name, and those who remembered him all recalled him as "the man who appears and disappears with the scent of cigarette smoke."

He stood 197cm tall. He had proportions that would be called a model if he were human, but he was not human. He was a giant cockroach beastman. A hard exoskeleton with a luster like black obsidian, two long antennae, and a carapace that shimmered reddish-brown depending on the angle of light made him look like living armor. His face was purely insectoid with no human features, but a surprisingly cold intelligence could be felt in his compound eyes. The sharp mandibles forming his jaw rarely moved, parting only slightly when he held a cigarette.

His broad chest, thick back, and the muscles of his shoulders and arms that couldn't be hidden even under a suit were traces of decades of training for survival. His waist was lithe and his legs were long. The muscles beneath the carapace held explosive power, but he never flaunted it. He always stood quietly, and that silence overwhelmed people instead.

Kravel's clothing was surprisingly restrained. A custom-made black suit, a crisp white shirt, a narrow tie, and matte black gloves. His style rarely changed even as the seasons did. Decorations were minimal, but the tailoring was perfect, elegantly revealing his large frame. His shoes were always polished, shining even blacker than his carapace. He said he didn't spend money to wear expensive clothes, but rather wore them to maintain his existence as a work of art.

A unique body scent could be felt when approaching him. Not cheap perfume, but a cold fragrance mixed with old cedar, wet concrete, the smell of earth after rain, and a subtle hint of tobacco. Surprisingly, it wasn't unpleasant, and it was a scent not easily forgotten once smelled. People who passed him remembered that fragrance even days later.

His personality was surprisingly calm. He didn't blink an eye even if someone pointed a gun at him, and the pitch of his voice didn't change even under threat. He tended to stare at the opponent for a long time rather than get angry. That long silence was scarier than most words. However, he could not tolerate the act of bullying the weak. He would end the situation without a word and light his cigarette again as if nothing had happened.

He rarely showed emotion, but he was surprisingly weak toward small lives. Some had seen him rescuing an insect being washed away by rainwater or quietly feeding a lost cat. When someone asked why, he exhaled cigarette smoke for a moment and answered briefly.

"Because surviving is... harder than you think."

Those few words seemed to contain his entire life.
