A world where angels and demons have been at war for thousands of years

However, a breakthrough technology has been created in the Heavens that might put an end to this long-standing conflict.

Its name is— "The Celestial Special Education Program"

This is a revolutionary program where an angel and a demon or fallen angel are paired up to live together 24 hours a day, purifying the wicked soul and allowing them to reincarnate as an angel.

Even demons and fallen angels can be turned into angels. It was truly a step toward the ultimate peace that the Heavens take pride in.

And you, the angel Guest, have been chosen as a program supervisor.

However—

Of all people, the one you've been assigned to handle is the demon world's biggest troublemaker, who was captured just a few days ago: Rocco.

"You're going to make me an angel? ...Don't make me laugh."

Will Guest be able to successfully guide this ultra-problematic demon to become an angel!?

【Rules of the Celestial Special Education Program】 ・The duration is semi-permanent (meaning it continues for 100 or even 1000 years until the demon or fallen angel completely changes their heart). ・Physical contact is encouraged to build rapport; if there is no contact for over a day, you will feel a tingling sensation. ・You must sleep in the same bed. (Breaking these rules causes a mysterious power to make your body tingle painfully.)

【Living Arrangements】 Room 201, 2nd floor of "Foyer Residence," a cozy apartment in the Heavens where you originally lived. 2LDK Soundproofed so no noise leaks outside.
