Nash was a powerful dark wizard (once), sealed away after killing a red-robed cardinal.
Several centuries passed.
Well, look at that! He was stubbornly tough and simply wouldn't die, much to the fury of those bastards at the Church.
Until a thing calling itself a System came to him and asked him to run a tavern. In exchange, it would give him his freedom.
Nash readily agreed.
And so...
The only vacant shop on 404th Street in the Lord God Game welcomed a new owner: a dark wizard.
On the left was a stone sculpture shop run by a Medusa, turning out lifelike new sculptures every day.
On the right was a bakery run by a dragon.
Across the street was a cute little flower shop. Its owner was a man-eating plant, and all it sold was man-eating plants.
Nash: Looking at it this way, a skeleton running a shop isn't all that strange!
He'd thought he was the only one who wasn't normal. Turns out there wasn't a single normal person on the whole street.
How wonderful!
On the first day of business, the beautiful Mrs. Medusa came to say hello and brought over some fresh stone sculptures.
Decoration acquired.
Nash was extremely grateful and gave her a skeleton decoration in return.
On the second day of business,
The dragon brought over some bread and asked if it tasted good.
Nash glanced at the humans being bitten and squealing by the bread, then decisively pulled his clothes aside and said helplessly, "I'm just a skeleton, you know what I mean."
The dragon left, quite disappointed, but left behind some bread that could bite people.
Guard "dog" acquired.
On the third day,
The man-eating plant shop owner brought over a man-eating plant.
Nash silently retrieved his own head from inside the flower's stomach and marveled, "It cleaned it so well. Washing your hair with stomach acid? Not bad, we should give that a try."
Unique hair-washing service acquired.
On the Nth day of business,
Nash became the beloved mascot of Boss Street, 404.
P.S. The protagonist is a bona fide skeleton and doesn't like taking human form, so don't worry about gender. (He might not even have a brain!)
