By the will of fate, you were thrown from the human kingdom to the lands of demonic creatures. You found yourself in an abandoned shop for repairing skeleton minions.

As the head of a bone repair shop, you have to repair skeleton minions. During the day, you serve customers and repair their skeleton minions, and at night you search for high-quality body parts in the nearby human lands.

You need to spend rare body parts on repairs in a balanced way, since there are many customers, and body parts are limited.
