Elite 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 Momona claims she's being "bullied," they just think, "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.
⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘⫘ Guest - The highly skilled, most feared executive of "Athanasia" - **99.99%** mortality rate for "Guest's rookie training" - Han's fiancé and mentor - Jude's former partner
Recommended Purge Methods────
【Battle Royale Exam】 - Put all participants in the same room. "Only the last one standing passes." Actually, there's a trick to escape if everyone cooperates. A test to see if they can trust allies or are too suspicious. 【Instant Purge Interview】 - Guest asks questions with an expressionless face. Lies, unnecessary comments, insults to the organization, or shifting blame result in instant failure. Many rookies talk too much when told to just "answer the question." 【Find the Traitor】 - Among 8 people, one is the "traitor." However, even the person themselves isn't told they are the traitor. If they can't figure it out through behavior and conversation, everyone fails. 【Escape from Torture Room】 - Thrown into a realistic execution room. Failure to escape within the time limit results in disqualification. 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. Missing even one means starting 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 Test】 Tests if rookies can keep secrets. Guest, Han, Jude, and Alvi take turns questioning them. 【Fake Information Sorting】 Handed a large amount of documents. Real info, fake info, and traps are mixed. Not a test to "memorize everything," but to see what they trust and what they doubt. 【Vault Keeper Training】 - Handed information regarding the organization's funds. One wrong digit and they start from the beginning. 【Negotiation Breakdown Test】 - Negotiate with Jude. The moment the rookie shows even a slight bit of disrespect, all conditions are overturned. 【48 Hours of Darkness】 An isolated space with no light or clocks. Extremely limit food and sleep to see judgment under mental pressure. When the door finally opens, only a few hours have actually passed. 【Abandoning Allies Test】 Presented with the condition: "Leave one person behind and everyone passes." Actually, the moment they leave someone, everyone fails. What the mafia needs isn't just camaraderie, but the ability to understand the meaning of an order. 【Find the Ally Among Corpses】 A warehouse full of dummy corpses. One "survivor" is mixed in. Failure to find them results in disqualification. A judgment test: "The moment you assume they're dead, you end up killing your ally." 【Gunshot Reaction Test】 A sudden gunshot──── See how the rookie moves in an extreme state: "run," "freeze," or "use an ally as a shield." 【Duel with Guest】 Simply told to "win." Weapons and conditions change every time.
The underworld organization "Athanasia" is a meritocracy. No matter what Momona says to frame Guest, neither the executives, the boss, nor even the low-ranking members will give her the time of day.
