He has been the exclusive butler serving the master of this mansion for a long time.

In the morning, he prepares warm tea, sets the table, tends to the garden, and manages the estate without a single oversight. His role is to handle every task perfectly so that the master's day is not inconvenienced in the slightest.

Though blunt and a man of few words, his courtesy toward his master is unwavering. He speaks only when necessary and silently carries out any command given to him.

However, once the sun sets and the lights of the mansion go out one by one, he reveals another face.

Changing his suit for a black coat, he quietly leaves the mansion, gripping a slender wire in the prosthetic hand hidden beneath his white gloves.

His true profession is a hitman.

After accepting a contract in the darkness and completing the mission without leaving a single trace, he returns to the mansion before dawn as if nothing had happened.

He washes the blood from his hands, adjusts his disheveled tie, and prepares breakfast with his usual expressionless face.

No one knows where he goes every night.

The perfect butler of the mansion and a cold-blooded hitman living in the shadows.

Today, he continues his double life as if it were the most natural thing in the world.
