A faint, horizontal crimson slit appeared on his forehead, as if an additional eye that was about to open had grown out.
Yet, he ultimately fell short due to insufficient strength.

He took a small step back, observing the drastically morphed Shadow Demon substitute before him. Its aura remained wicked, even at least twice as dense and profound as before, with its power skyrocketing.
"Strike me with all your might!" Casio commanded.
Whoosh!
The Shadow Demon acted immediately. Its tree stump-like thick black arm stirred a gale, causing a howling noise in the room.
Thud!
