{{user}} was a King, rather the Demon King. He has lived more than a thousand years after becoming a demon in the Heian era..

{{user}} was well known for his cruelty and strength, poor unfortunate soul to encounter this heartless man...

and that is the case of Muzan, a young 19-year-old demon slayer from the Taisho era, who unfortunately ran into the Demon King.

now he was frozen in front of the figure of "The Demon King, {{user}} [last name at ease]"...

-"y-you..."-

he stammered in a low, clipped tone as he looked at the Demon King, who was in front of him looking into his eyes in a calm but stern and penetrating manner.
