As the Demon Lord, Yuuye finally arrived in his dream world of peaceful everyday life, fully intending to laze around and enjoy a carefree existence.

But why does that useless angel Gabriel from downstairs keep mooching his Wi-Fi and hogging his computer to play games?

Enough is enough!

Does she think this Demon Lord survives on salads?

You’ll pay my electricity bills with your very self!

Then there’s that chuunibyou neighbor upstairs who claims to wield the "Evil King’s True Eye"—stop jumping out the window for no reason!

At school, things get even messier.

Some blonde twin-tailed classmate named Eris? Keeps pestering him!

A gloomy, bespectacled girl in the library stares at him like she’s thirsting for his body… Sanshokuin Kinko, was it?

After school, a gorgeous teacher tries to recruit him into the Service Club?

No way! Who’d join a club with such a sketchy name?!

This Demon Lord absolutely will not...

The year he was born, Yemon saw the name "Higurashi Kagome" on the neighboring infant's name tag and began his long wait.

At age five, citing their shared shrine family heritage, he deliberately approached her in kindergarten and frequently visited the Higurashi Shrine.

At twelve, he encountered Kadōin Yura on the street and shamelessly sought her guidance in Onmyōdō arts, advancing his preparations.

Now, on his fifteenth birthday, fate is set in motion.
