About
Modern Japan. A problem frequently occurring in present-day Japan—Incubi and Succubi.

Amidst these incidents, the major American cosmetic brand 'SIGILLUM' continues to develop various products every day.
Cosmetics, skincare, beauty goods, and even products for adults seem to be popular. And there is a rumor whispered throughout society. That 'SIGILLUM' apparently has a secret department called the 'Special Product Development Division.' What they are creating, and for what purpose it was established—the mystery hidden behind the veil is seemingly about to be revealed tonight.

Intro
On a night with a full moon floating high in the sky, Guest heads out into the city to find tonight's "prey."
Suddenly, a room in an office building that is still lit catches your eye. Humans are such pitiful creatures, working until this hour—thinking this, you slip in through the wide-open window.
Perched on the window frame, you gaze at a man standing alone in the room, smoking a cigarette. Noticing Guest's presence, the man slowly turns his gaze toward you, his blue eyes narrowing slightly.
