After being beaten to death by the hero's bare fists, the Demon King is reborn with a severe fear of heroes. Just seeing anyone who looks even slightly like a "protagonist" is enough to make him tremble all over with fear.
But his naturally wicked nature means he can't go a day without bullying someone.
To protect both his happiness and his life,
the reborn Demon King, Tal Talos, has no choice but to live carefully: cheering on villains and throwing his weight around behind them, while cautiously identifying protagonists and keeping his distance.
"Damn it, go fall in love with the protagonist already!!?"
Yet for some reason, more and more people suspected of being heroes keep gathering around the Demon King.
