Summary
In a world where Humans and Monsters exist together with mild tensions here and there, your only issue is trying to find a place to stay, growing tired of sleeping in your car.

Summary
‘What a day!’ Tanya thought as she drove out of the skeleton’s gigantic mansion driveway with her pretty pink corvette.
She didn’t really expect herself to be moving in with an old friend of hers but what was life without uncertainty and surprises? If her ex hadn’t decided to sell all his possessions — including the apartment they lived in to take a spiritual break in the Himalayan mountains she wouldn’t even be here in the first place! Reunited with her old friend!
Or, a rather dumb take on the anti-harem stories. Usually our antagonist happens to be a girly girl who loves shopping and all whilst the Reader is someone who loves to reads books and is nerdy. So I’ve decided it might be fun to write one where their positions are swapped!

Summary
It’s been a few years since monsters had escaped the underground. At first, people were overjoyed when the monsters were getting rid of the mafia, thinking that they would finally be free.
Only to have that glimmer of hope snuffed out as the monsters established their own mafia.
You tried to stay out of it all. Kept your head down, paid your dues on time, never looked towards any sounds that seemed suspicious. This life was rough. Luckily, there was always a certain feline who always cheered you up.
When your cat escapes your apartment, you’re beyond upset. Missing posters, posts online, asking your neighbors, you do anything to get your precious friend back home.
As weeks pass, you begin to lose hope that he’ll ever be found, only hoping he found a home with a rich owner rather than thinking about the possibility that he's dancing among the stars right now.
You nearly sob in relief when you get a call saying they found your cat. After talking to the stranger and agreeing on a pickup spot, you arrive with a smile, only for the thank you speech you had prepared dying on your tongue as you see just who found your fluffy companion.
The very monster mafia who had taken over your town.-

On the other side, the Vikings, a brutal people, in search of ever more important conquests. They exploited every possible opportunity, to win.

In all this, you are in the middle... What happens when a human with magical powers like you, ends up in the middle of a war, of which you did not want to be a part?
You wanted to stay away from all this... But a pack of very stubborn skeletons will drag you into something much bigger.
