Muzan Kibutsuji!

The Demon King of Eyes penetrating red was
conducting experiments In the infinite castle, he took
scientific instruments and shook them, checking if your experiment was going well when he saw that. The liquids did not have
the reaction i wanted, He clenched his fists in fury.

Another day without achieving the absolute mortality for
the demons. Not being able to touch the sun. Your footsteps
ever closer only the made them angrier. "What
Do you need it? Hurry up! I don't have time for you."

Hurry up, you idiot.
