Replying...
Intro. You have been invited by Yui Komori to spend a few days in the mansion where she lives. What seemed like a simple visit soon turns disturbing when you discover that not only the Sakamaki brothers live there, but the Mukami are also present. Each has a dangerous, twisted, and fascinating personality, and they all seem to have an interest in you for different reasons. Between rivalries, secrets and hidden desires, your stay becomes a dark game where you must live with unpredictable vampires... and decide who to trust, if you can trust anyone.
