I'm the Mafia Heir, Pay Up!

I'm Zhongyuan Xiao, and I grew up in an ordinary single-parent family.

My dad's name is Zhongyuan Zhongye. He's a corporate wage slave, and apparently the president of some company. His greatest wish is for me to study hard, preferably getting into Tokyo University to make up for the fact that he started working for someone at fifteen and never got a proper education.

Don't ask where my biological father went. He jumped off a building for his unattainable first love. I don't have a father like that: D

My everyday life was perfectly ordinary. The Yokohama specialties of mafia shootouts, ability users brawling, and the government chasing criminals all seemed a world away from me. I was just a bystander watching the drama.

Until one day, I got caught up in a mafia fight, and my classmate and I were only a tiny bit away from dying on the spot.

Yokohama's largest port organization put on an immediate show of welcoming its Dragon (Young) King (Master) home.

Oh my god, I'm the Port Mafia's young mistress.

I'm Zhongyuan Xiao. I used to think I was just an ordinary rich girl, but I never imagined I was a rich girl in the Port Mafia.

Aunt Hongye, who went to amusement parks with me, was an executive in the organization.

Mr. Sen, my family doctor, was the predecessor to the previous boss.

Sister Yin, who picked me up and dropped me off at school every day, was the boss's secretary.

And my dad, the ordinary wage slave in my eyes, was the current boss of the Port Mafia.

People used to joke that I must have a throne to inherit because I turned down so many suitors. I never imagined my family really had a throne for me to inherit!

The uncrowned king of the underworld, more or less, isn't that a throne?

This is going to kill me!

[Bonus scene?]

One day, Zhongyuan Xiao, now the young mistress, texted an online friend:

Me, the mafia heiress. Send me the money! Seven billion! When I take over as boss, I'll make you the most respected executive!

The recipient was former Port Mafia guerrilla captain, Nakajima Atsushi, wanted for seven billion, now working at an orphanage: ...?

1. The female lead is Zhongye's daughter. Dazai jumped off a building from the start. Zhongye, his surviving spouse, raises their daughter and runs the organization. Dazai lives on in conversations and memories. (He isn't entirely dead, actually.)

2. An ABO setting, to provide a reasonable explanation for Xiao's birth.

3. The female lead is actually not a good person.

4. The female lead has no love interest.

5. This is a prequel to The Years I Stirred Up Trouble in Yokohama.
