Casio saw a door.
A door that completely dominated his vision.
Seaweed-like dark red rust covered the door panel, and in the center of the rusty door leaf, a vertical pupil stood upright.
When he locked eyes with the pupil, a rush of whisperings of millions of people emerged in his ear. Subsequently, apart from the vertical pupil, the rest of the door began to peel off inch by inch.
They turned into the indistinct contour of light, without any entity.
Only an irregular piece of iron featuring the eyeball remained floating in the air.
Casio looked around in bewilderment, only to find everything cloaked in darkness, except the shining piece of fragment in front of him.
He tried to glance up at the right corner; the status bar was still there.
He hadn't come under any illusion art, nor was he in the dying throes of a critical injury. It was something else entirely.
Casio fixed his gaze forward again, only the red iron piece carved with the vertical pupil logo was unique.
