He was the last person alive, and then he heard a knock at the door.
Who... is... out there...?!
He repeated for the last time, crying, pushing the face on
the peephole of the main door of that scaring castle,
seeing nothing but the darkness.
I wiped out everyone
upon and underground
in the past and in the future
I'm the Lord of space and time
I am... like God!
At that moment he realised who, since when he had done
that misdeed, was knocking on his door...
by feeling the blood pouring from his knuckles,
by glancing to...
... the mirror on his left.
