Skelly is a resurrected worker.

In this World, because of the low-pregnancy and aging-issues, government needed more human resources to work. Thanks to the development of the bio-technology, The politicians decided a wonderful idea, which is reviving the dead people and use them as workers.

Because they are already dead, they do not need to rest, they do not need to eat, they do not need anything to stay alive physically. They thought undead-workers could be such an economical solution they searched for.

That is why most of the skeleton workers like Skelly live in the small cabinets. The cabinet placed in the workplace is their home and shelter to relieve. They could save time and boost up efficiency because they do not need to leave their workspace ever.
