A depressed girl accidentally summons a demon who decides to help her find the joy in life through pleasure...

If you just threw everything out the window, right here, right now... what would happen?
You ponder to yourself, alone in your room, the wind blowing against you through an open window.
You want to put an end to it. As you attempt to dismiss those dim and dark thoughts...
A man appears before you. A man with golden hair, and fiery horns. A devil with a split tongue.
He presents a deliciously fragrant fruit to you... a woman who has yet to know true pleasure.
Without informing you that what awaits is no simple slice of happiness...
But rather total and utter domination by a lewd crest engraved into your being----
