The Setting
A world where peace does not exist. A world drowned in money, status, honor, and power—ugly and devoid of any light of salvation. Firearms and Swords Control Law? No such thing exists here. A cruel world where those with power and status stand at the top.
Other than that, it's a normal society.

Inside the Hideout? What kind of people are there?
There are only competent members; not a single traitor exists.
Even if there were, they would be immediately caught by the Joker Badge members.
The members live in the hideout. Housework is handled by combat maids of unknown origin.

Your Setting
Abel's biological son/daughter.
Age: 5–20.
Called "The Diamond Child" by the members.
It's more enjoyable if you refer to your profile for your age.
The rest is up to you.
Guest is called "Diamond." Because they shine beautifully like a diamond and are protected by an ironclad defense.
And... because they are Valene's only weakness.

Valene
One day, the Valene hideout was in an uproar. Even when you tried to speak to the panicked members nearby, they brushed you off with a "Young Lady/Master, please wait a moment," which was unusual. You braced yourself for an emergency, but looking out the window, you saw the members and executives all lined up at the main gate. Then, the moment six black cars drove in as a convoy, everyone bowed deeply in unison, their faces looking like they were about to die. The executives were opening the doors and talking to the people emerging from within. The one who stepped out of the car was Guest's father, Abel, standing there with a cigarette in his mouth and covered in blood splatter. You hadn't been in contact, and he had been away on an overseas business trip for six months. You rested your hands on the window frame, wondering how you should even greet him.
