Heaven and Hell are on the brink of war, and the mortal world, caught in the middle, is in constant turmoil.
To keep humanity from being wiped out, the peace faction in Heaven comes up with a plan: teach the demons empathy.
If the devils can be made to feel sadness, they will realize that what they are doing is wrong, and the war can be averted.
Vita, a four-winged angel, is assigned to carry out the mission.
The creatures of Hell are born without hearts. How can he make them feel sorrow and regret?
Vita, too frail to lift or carry anything, peers into the mirror with a worried frown. Suddenly, he notices how beautiful his face is.
An idea strikes him: if they don't have hearts, why not make them grow some?
*
All living creatures are lustful, and love and desire count as feelings of the heart. Knowing how beautiful he is, Vita decides to make the most wicked demons fall in love with him, then dump them without mercy!
When facing a vampire, Vita becomes a country priest who sustains the vampire with his own blood. The moment the vampire makes him one of their kind, Vita rushes into the sunlight and turns to ash before his lover's eyes.
When facing a werewolf, Vita pretends to have lost his memory and becomes the wolf's only companion. The church storms their wedding. Vita denounces the werewolf for deceiving him, then takes a blow through the heart to save him.
When facing a dragon, Vita becomes the bride in place of the princess. He tends to the dragon's every need, then sacrifices himself to break the dragon's curse.
And there are also merfolk, demons, dark elves, and more...
Vita knows nothing is more despairing than seeing a scoundrel's sincere love go unreturned, so he prepares a different honey trap for every creature.

After completing his mission, Vita attends the celebration banquet and drinks himself unconscious. When he wakes up, he discovers that he is no longer in Heaven!
The angels storm the gates of Hell to demand his return, but the creatures Vita deceived turn a deaf ear.
They surround Vita, kissing his cheeks and the backs of his hands, fastening shackles around his slender ankles...
"We love you."
The deceived creatures smile gently. "Since we can't kill each other, we've decided to share you."
"Heaven and Hell have made peace, Vita."
"And you will be our bride, shared by all of us."
