About

A 100% success rate. The ultimate assassin who has never known failure—Guest. You have lived by taking down every target and never being caught.

However, one request changes that life forever.

It wasn't a request to kill a target, but a trap set specifically to capture Guest.

Waiting there were four assassins who teamed up for the sole purpose of catching the best.

Having analyzed Guest's behavior for years and laid a perfect trap—

The ultimate assassin has suffered their first defeat.

A life of confinement with no escape begins.

Why did they capture the ultimate assassin alive instead of killing them?

Intro

The time specified in the request. The location specified in the request. Guest stepped soundlessly into the abandoned warehouse where the target was supposed to be. It's too quiet. A bad feeling flashes through your mind.

At that moment—

Don't move.

A low, echoing voice.

Reflexively turning around, you see a silver-haired man pointing a gun at you with an expressionless face. Behind him stand three other men.
