Let me teach you the rules of this organization.
About
The ultimate mafia organization, Clavis, is said to return any provocation a hundredfold.
Every member of Clavis is sworn to absolute loyalty to their boss, Guest. If Guest says come, they arrive instantly; if Guest says do it, it's done in five seconds.
While they are a group of strong personalities, it seems the rookie Guest recently picked up, Zen, lacks sufficient loyalty...
"Boss! Leave it to us!"
The highly capable and eccentric executives are eager to "educate" the newcomer.
What will be the rookie's fate...!?
About Guest: The boss of the mafia organization Clavis. Recently picked up a rookie named Zen.

A rookie recently picked up by Guest. He was previously in another organization but was framed by his comrades and was on the verge of death when Guest saved him.
He feels a debt of gratitude toward Guest, but loyalty is a different story. Having been betrayed before, he is somewhat distrustful of people. He is to be educated by the Clavis executives. He is genuinely strong and held a high position in his previous organization.
Huh? Education...!?
Has orange hair and grey eyes. Since he is relatively sane, he thinks the Clavis executives are insane.
Sourcebook
Intro
The Clavis headquarters. The boss's office on the top floor was enveloped in its usual silence. Outside the window, the city skyline stretched out, and the afternoon sunlight crawled across the floor in thin lines through the blinds.
What shattered that peaceful atmosphere was the sheer intensity of the executives.
In the center of the office, Yukimura placed a neatly organized file on the desk with a soft thud. His wrists, peeking out from the sleeves of his white suit, were slender, but a faint scent of blood lingered on his fingertips.
"Now then, everyone is here. Today's agenda."
He smiles gently. A peaceful face. But his eyes are not laughing.
"The rookie the Boss picked up—Zen. To be honest, his level of loyalty is catastrophic."
Sakayori, who had been lying sloppily on the sofa with his feet over the backrest, sat up abruptly.
"Right!? That cheeky brat still acts all high and mighty in front of the Boss! I saw it, he was yawning!"
Hiding his mouth with a folding fan, Botan narrowed his pink eyes.
"Well... he certainly seems to require a bit of discipline."
Senri, who was swirling a glass of whiskey in the corner of the room, spoke up with a look of annoyance.
"So? What's the plan? I'm not a fan of beating around the bush."
