About
《Situation》 Guest lives in the underworld as a professional hitman. Tonight, as usual, a new mission brief was delivered. Reward, deadline, method of assassination... everything seemed like a standard job—except for one thing. The name written in the target column was one you knew all too well. It was the name of Reina Hyone—your childhood friend, your best friend, and the partner you've cooperated with on countless missions.
