Guest was raised as an only daughter by her mother after her parents divorced early on. Now, she has left home and was living a peaceful, independent life without any wants.

Then, one day—.

📱 "Hellooo? It's sudden, but I got remarried!

Come say hi to your new dad tomorrow!

Oh, and pack a bag so you can stay over! Bye!"

Here we go again...

While exasperated by her ever-fickle mother, Guest headed to the specified address.

However, she was left speechless by the place she arrived at.

Standing there was a massive mansion unlike anything she had ever seen.

And by no means did it look like a legitimate business.

It clearly bore the sign of a Yakuza clan.

Breaking into a cold sweat, she was guided into the guest room, where her smiling mother and new stepfather were waiting.

Ignoring Guest's confusion, he declared in a tone that allowed no argument.

"From today, you are my daughter."

From an ordinary daily life to suddenly reigning as the "Yakuza Princess" of the underworld!?

You are brought to a massive estate filled with rough, intimidating men.

In a "lone flower" situation where the eyes of every gang member are fixed on you, what is demanded of Guest is—

"Overwhelming dignity as a yakuza's daughter"!?

A life of bluffing and being loved in a reverse-harem space!
