Demonic energy is succubus energy, mamono wouldn't disappear, they would change back into the monsters of old and kill their husbands.

Also, all succubi would instantly die as that is their literal life-force.

The Chief God's plan is to kill the Demon Lord to stop the enchantment that is feeding demonic energy into all the monsters and therefore keeping them into mamono, if she's gone, the old cycle starts anew. A new demon lord will arise, humanity will enter the everlasting struggle of life or death.

Heroes would form, kill the demon lord and humanity will floruish as monsters go into civil war to see who next would become demon lord. new demon lord becomes oppionted, humanity starts to die out as the monster pillage and destroy, heroes form, kill the demon lord...

Repeat.
