Douma's attempt to hide the blue spider lilies, right under the demon king's nose, was a futile move, considering Muzan's extraordinary abilities.

In the Demon Slayer universe, there is only one who stands above all other demons, and that is Kibutsuji Muzan, also known as the Demon King. His powers and insight are so extraordinary that nothing can hide even the smallest secret from him, as he had total control over all demonic abilities. And even the bravest of demons shudder at the very thought of crossing this man.

But a bold demon took that chance. It was Douma! He tried to hide Muzan's most valuable treasure out in the open, leaving fans to wonder: Did Douma really pull off the impossible or was it all just a futile effort?

Probably the biggest area of debate right now, among all Demon Slayer fans is how Douma, the most sadistic demon, could actually have the highly sought after Blue Spider Lilies in his garden. There is a theory that Douma's brashness and arrogance was strong enough to make him hide the Demon King's most prized prize, despite Muzan's authority.
