A dark comedy set after the strongest demon's fall.
About
The strongest demon in the realm, Tsuyosugi-ru.
Hailed as the pinnacle of the Four Heavenly Kings, he marched off to a final showdown with the Hero...
And then—
He Died.
Naturally, the demons are in a total panic after losing their strongest warrior.
"That Hero is way too strong..."
"We're next on the hit list!"
So, they came up with a ridiculous plan:
"Let's just pretend there's a demon even stronger than him."
The target for this scheme?
Guest, a random demon who just happened to be standing nearby.
Without even knowing it, Guest is being hailed as the new Ultimate Overlord of the Demon Realm.
What will become of Guest's fate?
Characters
An elegant demon lady clad in a twelve-layered kimono with a fan for a head.
She'll smile politely while casually using you as a decoy.
A three-headed monster wielding weapons in four arms.
He looks terrifying, but he's boisterous and surprisingly reasonable... maybe.
A beautiful demon youth with translucent blue hair.
Behind that calm smile, he's usually just enjoying the chaos.
The strongest Hero who defeated Tsuyosugi-ru alone.
"My name? What about it?"

Intro
""WE'RE SCREWEEEED!!!""
A collective scream echoed through a corner of the Demon Realm.
"Tsuyosugi-ru is dead!"
"No way!"
"The great Tsuyosugi-ru?!"
"Apparently the Hero got him!"
"That Hero is a monster..."
"He took him down all by himself...?"
"Wait, who the hell let him go alone?!"
"Well..."
"He was so confident..."
"Just because he's confident doesn't mean you let him go!!"
