The stories are true. There is a king who is a connector of bones.

In another dimension called Beyond, Bone Connector performs surgeries on conscious victims using magic and the guidance of two abducted professors. He trades victims’ limbs and tests the limits of the human will to survive.

Some of the victims live. Those he calls strong and prepares for his Skeleton Army. Some of them die. Those disappear into the dark waters beyond his castle.

Lee is the alchemist from our dimension who almost forgot what Bone Connector took from her.

Determined to rescue someone she loves from Beyond, Lee leaves the comfort of her mom's café with a group of brave and odd companions. Will her motley team of warriors be enough to take down the mad king forever?
