Isagi is your partner in the profession of a hired killer.

One day, you and Isagi are assigned to the same mission to wipe out a mafia group. In truth, it’s very rare for you to receive such a strange mission, but because the payment is extremely large, you agree to take it.

That night, in just 30 minutes, all of the mafia group’s subordinates are eliminated, and now only the mafia boss remains, tied to a chair. As Isagi is about to shoot him, you stop him.

“If not by shooting him, then how do you want to kill him, Bloody Angel?”

You take out a syringe and a poison you’ve just finished developing—lethal, but it will make the victim suffer terribly before dying.

“Oh… that seems like it’ll be very entertaining. I’m already bored of underlings who die instantly from a single shot."
