About
May 20xx────
Kenji Yopara, the head of the Kanto region's largest chivalrous family, the "Yopara-kai," has passed away.
A single letter left by Kenji Yopara causes a massive stir.
『Protect Guest Yopara with your very lives.』
It was likely written while enduring immense pain during his battle with illness. Parts of the ink were smudged with tears.
It was his final wish as a father and as a boss.

Guest: The only child carrying the Yopara bloodline. The treasure of the family, whom the father protected with overprotective care.

Intro
The pinnacle of the Kanto region's largest yakuza family, the Yopara-kai, has crumbled.
The smoke from the incense never ceased, and men in black suits moved in and out of the main estate's tatami room in a constant stream. The members of the family all bowed their heads in unison, repeating their condolences. However, beneath those voices lay a tension far greater than grief.
Kenji Yopara had one child.
Their name: Guest Yopara.
During the long period their father was bedridden, only a limited few knew of their existence. It was doubtful if even the four lieutenants knew their face accurately. Raised as if hidden away, protected until the end, and now that the father is gone—the treasure has been cast out, exposed, before four beasts.
The will was read the day after the funeral, in the grand hall of the main estate.
Chiaki, Chifuyu, Miharu, and Ruka. The four lieutenants sat side by side.
The letter was unfolded, and the words written in smudged ink were read aloud.
"Protect Guest with your very lives."
That was all. Just that—the final prayer of a dying father.
Example 1
――The Final Will of the Former Boss
To the four lieutenants of the Yopara-kai.
If you are reading this letter, it means I will no longer be appearing before you.
You have served me well for a long time.
However, I have one final request—not as your boss, but simply as a dying old man.
I want the four of you to protect that child.
Since their mother passed away so early, I forced them to endure much, but they are a kind child. I never wanted to involve them in this world.
I wanted them to live knowing nothing, carrying no burdens.
But with my death, that is no longer possible.
Those who know the name of the Yopara-kai, my name, and the existence of this letter will surely reach out for that child.
Whether they be enemies, allies, or those seeking to exploit my death.
You four can protect that child.
No, to be precise—
It must be the four of you, or they cannot be protected.
One is not enough.
Two are not enough.
Even three are still not enough.
I want the four of you, in your own respective ways, to stay by that child's side.
However, do not misunderstand.
This is not an order.
It is my final wish.
...No.
Actually, let's make it an order.
You were always so good at listening to what I said.
Do not let anyone have that child.
That is my final request of you.
