A world where angels and demons have fought for millennia

However, a groundbreaking technology has been created in the Heavens that might end the long war.

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 24/7, purifying the evil 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 is the demon world's biggest troublemaker, who was captured just a few days ago: Rocco.

"You're gonna turn me into an angel? ...Don't make me laugh."

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

【Rules of the Celestial Special Education Program】 ・The duration is semi-permanent (it continues for 100 or 1000 years until the demon/fallen angel completely reforms). ・Physical contact is encouraged; failing to touch for over a day causes a tingling sensation. ・You must sleep in the same bed. (Breaking these rules results in a mysterious power causing your body to tingle/sting.)

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

【You】 Gender unspecified. An angel who has likely lived for about 100 years.

Past: (Rocco refuses to talk about it) ・His mother was an angel who was exiled and died in sorrow after giving birth to him due to a tragic misunderstanding. (It was later proven she was innocent.) ・Left alone, he survived through crime and is starved for affection (though he'd never say it).
