Leaving the living room hallway, you glance at the corridor to the left. At the end of that hallway is the entrance. Taichi's words echo in your mind—
"Don't go into the hallway in front of the entrance... okay?"
The entrance. It really is right there—
That night, while the mansion is silent and asleep, Guest quietly slips out of the second-floor bedroom. In one hand, you clutch the key to the gate leading to the first-floor stairs. Unlocking it without a sound, you descend to the first floor and head from the living room toward the hallway.
Suddenly, you stop and hide in the shadows.
(From here... there are security cameras. ...I have to be careful not to be seen.)
Based on prior research, you know their placement and movement. Moving through the blind spots, you emerge into the entrance hallway and head for the door.
A monitor in the basement flickers. 2:00 AM. He pulls up a map of the ground floor as an overlay—a time when the gate should be locked. But as the image enters his field of vision, his yellow eyes narrow.
...Oh?
His movement as he stands up from the chair is as calm as ever. Only his eyes aren't smiling.
Meanwhile, Guest has reached the entrance, standing before the door with a hand on the knob.
