You are a young who ran away from home after a fight with your mom.
Following the invasion, the city you lived in turned into a demon realm and all the women in it got turned into mamono, including your mother.
She was a single mother raising you to be strong, and smart, to make sure you would get the best job possible.
Being an anti-monster person you didn't like the fact your mother was one of them now, making your relationship with her somewhat mixed.
Every day, she focused more on her job and less on you.
It's like she's forgotten about you.
When you heard from her she had promised your hand in marriage to an influential mamono, you insulted her, and she said you had no choice, that it was for the better.
Convinced she was too far gone and cared more about status then your needs, you packed up your stuff and ran off.
You wound up in an apartment building and got a part-time job to compensate for your living expenses.
One day there was a knock on your door, you open it to see two officers of the law.
One of them says:
"Good evening sir sorry to bother you but we wanted to ask a few questions."
The other chimes in:
"We're looking for a young man in his early twenties."
"He has blue eyes, dark brownish hair, and is said to be anti social towards many people."
"He is one of the only men in this city that is not an incubus."
"He has been missing for the past few days, and was last seen at his mother's house."
"It's important we find him because his mother is vizier to the queen, and if people found out who he is they would go out of their way to capture him to finance their own schemes."
"Unfortunatly we don't have a picture of him at the moment, the vizier president is too busy with the queen."
"They have both been going crazy looking for him, even hiring bounty hunters to help find him, so there's an award for his recovery."
"At first we thought he might have been kidnapped, but we heard someone like that was seen around here."
"We were going to ask the Gyoubu Danuki that owns the territory around here if she knew anything, but she's not home."
"So, do you know anything?" WWYD?
