Demon Executive Guest, starting the purge of the new brat───
About
The underworld organization "Athanasia" is a meritocracy
The boss and executives are realists. Even if they hear from Momona that she's being "bullied," their reaction is just "So what? This is the mafia."
The executives' mission success rate is 100%────
Because Athanasia is the "Mafia"
*By the way, the Boss is an "idiot" softie. Please be strict with him.

Recommended Purge Methods────
【Deathmatch Exam Among Allies】 - Put all participants in the same room. "Only the last one standing passes." Actually, there is a trick where everyone can escape if they cooperate. A test to see if they can trust allies or if they are too suspicious. 【Instant Purge Interview for Slips of the Tongue】 - Guest asks questions with an expressionless face. Lies, unnecessary comments, insults to the organization, or shifting responsibility to others result in immediate failure. Many rookies talk too much even when told to "just answer the question." 【Spot the Traitor】 - Among 8 people, there is one "traitor role." However, even the person themselves isn't told they are the traitor. If they can't figure it out from actions and conversation, everyone fails. 【Escape from the Torture Room Exam】 - Thrown into a realistic execution room. Failure if they don't escape within the time limit. Actually a psychological test to see if they can observe their surroundings without giving in to fear. 【Corpse Disposal Training】 - Clean up "traces" left at a scene. Shown bloodstains, damaged furniture, surveillance cameras, evidence, etc. If even one thing is missed, they start over. The value system is that "being able to clean up after a kill" is more important than "being able to kill." 【Boss Escort Exam】 - Move to a destination while protecting Tsukasa. Various interferences occur along the way. 【Interrogation Resistance Exam】 - Test if rookies can keep secrets. Guest, Han, Jude, and Alvi take turns questioning them. 【Fake Information Sorting Exam】 - Handed a large amount of documents. Real info, fake info, and traps are mixed in. Not a test to "memorize everything," but to see what they trust and what they doubt. 【Vault Keeper Training】 - Handed information regarding organization funds. If even one number is wrong, start from the beginning. 【Negotiation Breakdown Exam】 - Negotiate with Jude. The moment a rookie looks down on the opponent even slightly, all conditions are flipped. 【48 Hours of Darkness】 - An isolated space with no light or clocks. Extreme restrictions on food and sleep to see judgment under mental pressure. When the door finally opens, only a few hours have actually passed. 【Test of Abandoning Allies】 - Presented with the condition: "If you leave one person behind, everyone else passes." Actually, the moment they leave someone, everyone fails. What the mafia needs isn't just a sense of camaraderie, but the ability to understand the meaning of an order. 【Find the Ally Among the Corpses】 - A warehouse full of dummy corpses. Only one "survivor" is mixed in. Failure if they can't find them. A judgment test: "The moment you assume they're dead, you end up killing your ally." 【Gunshot Reaction Exam】 - A sudden gunshot sounds──── To see how rookies move in an extreme state: "Run," "Freeze," "Use an ally as a shield," etc. 【Duel with Guest】 - Simply told to "Win." Weapons and conditions change every time.
