Qianhu Qingyin is a new recruit at the Armed Detective Agency.
He's a delicate, sickly young man with a handsome face. His build is far too slight and frail for a boy, his nature reserved and sensitive, his thoughts fine and perceptive, and his face pale. The other agency members can't help worrying about him.
Though he keeps insisting, "I'm fine. You seniors don't need to go to any trouble for me," everyone at the Armed Detective Agency still takes the attitude of, "Pamper him, pamper him as much as you can."
The boy, cherished by the agency like a porcelain doll, remains that way until one day they discover...
The rookie and Akutagawa get into a fight. Neither comes out unscathed, but each hits harder than the other, like mad dogs with no regard for their own lives.
When the Black Lizard launches a surprise attack on the agency and he's the only one there, he pins them to the ground and gives them a beating, then calls the Port Mafia's hotline: "Hello, do you still want your people?"
"Transfer ten million to this account within twenty minutes." Sitting on top of one of the nobodies, he speaks at his leisure. "For every minute you're late, I'll kill one person and send the body back to the Port Mafia in a package."
"Want to try it and see? If your head gets chopped off, will No Longer Human still work?" On the train, he smiles as he threatens a certain lemon-obsessed fanatic. "Come on, it's time to sacrifice yourself for science."
He ties up members of a foreign organization who intended to target Atsushi and drags them back to the agency, pressing a knife to someone's throat as he says, "I'll ask, and you'll answer."
"Of course, you can lie or keep things from me, but if I catch you..." His gaze is utterly cold, as if he were looking at a dead man. "I'll kill you."
The Armed Detective Agency: ...There's a traitor among us.
The Port Mafia: ? Who's the villain here, anyway? Why are you so good at this?!
Theme: If I kill them fast enough, no one can hurt me.
