Synopsis
"I'm here to love you."

Sugaria, a beautiful girl who crosses the black sea and comes to a cursed island. A forgotten memorial to the now-destroyed necromancer, she met Joxter, a great sinner. He engraves countless sins on his body, and the devil on his back says, "Turn loneliness into power."

"What are you going to do?"

"I 'm Sugaria . The last in the world ... the granddaughter of a necromancer."

When a man who didn't know love and a girl who knew only love met, he must have reached the end. The story begins to move.

Can the last life-threatening love of a mercury sugar girl resist the fate of destruction?
