In the oppressive Omega Empire ruled by Emperor Duke, Hatsuki tries to survive as an assassin for Psi, the resistance movement led by Edgar, while also pursuing a relationship with the kindhearted local doctor Bruno. Unfortunately for her, Bruno is opposed to violence, and thus she leads a double life. When Bruno accepts an offer to study in the Metti Kingdom, Hatsuki's sense of stability falls away, leading to a number of potential futures depending on the player's actions.
A censored version of the game was published by Sakura Game and released on Steam, under the title Killing Time (not to be confused with the horror-themed FPS by Studio 3DO from 1995); however, this version was delisted in 2022. Another publisher, Shiravune (the people behind the Steam releases of Marco & the Galaxy Dragon and the Utawarerumono series), worked on a new version more accurate to the Japanese original, released internationally through Steam on August 24, 2023 under the title Marauder of Dystopia: The weakest go to the wall.
This game includes examples of:
- "Blind Idiot" Translation: In the (now-retired) Sakura Game version, in addition to translating "Psi" as "Sigma" and "Chloe" as "Coroey", bits of text such as the description of Hatsuki's equipped outfit were not even translated into English.
- Can't Bathe Without a Weapon: Hatsuki's sprite still has her sword even when she's bathing.
- Defiled Forever: At the start of the game, Hatsuki feels that she is unworthy of Bruno because of her history as an assassin. If Hatsuki loses her virginity to anyone except Bruno, she loses any hope of a happy ending for herself. Even if she kills the Emperor and all four of the Wild Trumps, she ends up as a drug-addicted prostitute.
- Depraved Bisexual: Tina runs the Empire's most elite brothel. According to one of the girls working there, she regularly forces prostitutes to service her, and her dialogue with Hatsuki makes it clear that she wants to do things to her.
- Despair Event Horizon: On any of the non-virgin paths, Psi's hideout is raided and most of Hatsuki's peers end up dead, and thus Hatsuki herself falls into a deep, self-destructive depression.
- Elaborate Underground Base: Psi has a multi-floored base underneath a church, complete with telecommunications, an armory, and a general store.
- Elite Four: Emperor Duke has the Wild Trumps - Jack, Tina, Goeb, and Dan.
- Eyes Out of Sight: Bruno, one of the few characters with their own portrait, has a dark shadow covering his eyes despite his hair not seeming to be all that long.
- The Empire: The Omega Empire rules the land of Omega with an iron fist.
- Face–Heel Turn: On the "Empire" path, Hatsuki is blackmailed into working for the Empire under threat of Bruno's death.
- A Father to His Men: Edgar serves as a substitute father figure to Hatsuki.
- Full-Circle Revolution: If Hatsuki kills Emperor Duke without remaining a virgin, the Omega Empire ends up being conquered by neighboring countries who decide to simply rebuild the existing apparatus for their own use.
- Hihi'irokane: Hatsuki's sword Rougetsu and Edgar's sword Shura are both stated to be made from Hihi'irokane, which the game translates as "scarlet gold".
- Honey Trap: One of Psi's top agents, Chloe, specializes in sleeping with targets, either to blackmail them or to assassinate them. If Hatsuki loses her virginity during the course of the game, Chloe trains her as a honey trap. Of course, if that happens, Chloe herself ends up being killed.
- I Have Your Wife: On the "Empire" path, the Empire manages to get one of their operatives near Bruno, and thus they blackmail Hatsuki into working for them.
- Improbable Infant Survival: One of Hatsuki's first meetings with Bruno involved them saving a young girl that was the victim of an Empire carriage hit-and-run.
- Jack the Ripoff: The Act 1 Boss is Jack the Reaper, a member of The Empire's "Wild Trumps" that is also a serial killer of women.
- Kick the Dog: The Empire Street mission on the "Empire" path is one long-ass dog-kicking session, as Goeb forces Hatsuki to publicly humiliate herself in exchange for getting to see Bruno again.
- La Résistance: Psi, a group attempting to overthrow The Empire through assassinations, espionage, and other secret missions.
- The Mole: Early into the game, there's a rumor of one within La Résistance, explaining how Hatsuki's gained a reputation despite her job involving stealth and not leaving behind witnesses. Adolf has been feeding intelligence about Psi to the Omega Empire, compromising several of Hatsuki's missions.
- Multiple Endings: There are multiple different routes and conclusions dependent on if, when, and how much Hatsuki indulges in lewd activities.
- Named Weapons: Hatsuki's katana is named the "Demon Blade Rougetsu".
- Names to Run Away from Really Fast: Hatsuki's nickname is "The Black Death", and at the start of the game, she's one of the most feared assassins in Omega.
- Self-Censored Release: The (now-retired) Killing Time version published by Sakura Game had much of the more objectionable content stripped out or heavily censored.
- Schmuck Bait: Jack the Reaper, upon being defeated, states that the empire forced him into evil work and asks Hatsuki to spare him. This is after a flashback in which Hatsuki was stabbed by someone that pulled the exact same trick, but the player can still choose to fall for it and get assaulted.
- Torture Technician: Goeb serves as Emperor Duke's head torturer.
- Weakness Turns Her On: In the virgin route, Hatsuki is attracted to Bruno because he's kind and gentle. Subverted in any of the non-virgin endings, all of which feature Hatsuki berating Bruno for being such a wimp.
