The contour was rather blurry, just merely a few intertwined black lines forming an oval, barely resembling a human figure. According to its position, this person was outside the alley of the single house, sticking close to the white enclosure wall.
A passerby? Drunkard? Or perhaps...
Casio blinked, opening his eyes, his senses, which were temporarily blocked, snapped back instantly. The entire world became three-dimensional.
He stood up and walked to the glass, opening the window.
He didn't turn on the light, he merely stuck his head out in the dimness to look below in the direction he had heard the noise.
There was a patch of green ornamental trees blocking the wall. The human contour that Casio sensed was on the other side of the base of the enclosure wall.
His gaze moved slightly, placing one hand on the window sill, and he jumped directly from the second-floor window. His tiptoe touched the ground without making any sound, not even the sound of a normal person walking.
