"When you kiss a monster, you turn them into angels.
If you'd kiss the Collector, he would turn you into a monster.
So... what happens if you would kiss a human?"

Her name is Kiss.

She travels the world to find monsters to kiss and turn them into angels—for the world has too many monsters and too few angels, she believes; too many shadows and too few stars in the sky.

But then she crosses paths with Zane, a young human man, a lost and lonely cello player, who tells her about the Collector—a monster who would turn her into a demon if she'd kiss him.

The Collector wants and claims everything that catches his attention.
And so, he starts hunting for Kiss.

Will she run? Will she stay and fight?
Or could Zane, a mere human, save her instead?
