Go To

Cartesio is a murdergame set in an industrial countryside town, where the characters spend a month residing in the motel and exploring the many locations in the town. Every week there’s both a task from the Sergeant that will involve lawbreaking and generally making the townspeople’s lives a living hell, and a murder case that will make all the players face against a culprit in a trial.

The goal of the game is not only to ensure your characters’ survival, it’s also to solve what exactly is going on in the town of Cartesio.


After eight weeks, those who have gained the Sergeant’s approval will be allowed to leave, and there are only two ways to gain it: commit a murder and successfully let a scapegoat be executed in your place, or do what the Sergeant wants you to do and help destroy this town’s peaceful days. The choice is yours!

The Mock Round began on May 6th, 2018 and ended on May 13th. Round 1 began on September 24th, 2018 and ended on November 24th.

This game provides examples of:

  • 0% Approval Rating: As time goes on and the tourists end up damaging more and more of the town both by doing tasks and committing murders, the townspeople's opinion of them starts going down.
  • Accidental Murder: What the sixth case turns out to be.
  • Actor Allusion: Wayne mentions Franciscus looking similar to a younger version of Philip U. Butler. Both of them are, appearance-wise, Expies of Battler Ushiromiya.
    • Also, during his confession in the fourth trial, Franciscus' icon changes to Black Battler and his truthful statements are colored in red.
  • Ambiguous Gender: Kino. Confirmed female as of Week 4.
  • A Birthday, Not a Break: Both Natalie and Osomatsu's birthdays pass while in Cartesio. Oso's even falls on the day right before the final investigation and trial.
  • Bittersweet Ending: The characters escape the simulated town, both living and dead, but they're all just clones of their original selves, and most of them no longer have their friends and family from home. However, most of them are determined to make a new life in this new world.
  • Advertisement:
  • Card-Carrying Villain: Clarisse, as well as Dabi - literally.
  • Cassandra Truth: Kino and Osomatsu attempt to tell journalist Robert Miller the truth about the circumstances of their stay during the Week 4 mission. He publishes their side of the story, but it's clear he doesn't really believe them.
  • The Cavalry: During endgame, part of the town distracts the Sergeant while another group, including the brainwashed mock round characters, tries to drive the visitors out of town. It fails, but they manage to keep up the distraction so the visitors can investigate the Lodge.
  • Cover Innocent Eyes and Ears: Bolin to Sakura during the Week 3 trial.
  • Crazy Enough to Work: In the second trial, Bolin is able to bend enough mud off everyone's bodies to provide comparisons to the suspects' footprints.
  • Culture Clash: Plenty of it, thanks to the characters coming from various different worlds with different types of basic setting assumptions.
  • Dead All Along: Nine, Clarisse, and Oda.
  • Death Is a Sad Thing: As Millium is slowly learning.
  • Deliberately Cute Child: Employed (alongside Crocodile Tears) by Millium against the townsfolk, to limited success. It works well enough with the police chief, but it just causes the journalist to peg her as the mastermind among the tourists.
  • Dirty Kid: Millium, unfortunately for everyone involved. It's mostly to get a rise out of people, though.
  • Disappointed by the Motive: In the third trial, it comes out that both culprits misunderstood the "immortality" motive. Rose expected cryogenic freezing, and Frasier thought it meant metaphorical immortality in the form of enduring fame. Some of the other characters are so annoyed that they volunteer for the execution immediately so they can be done with it and never have to acknowledge the stupidity again.
  • The Ditz: Nine.
  • Don't You Dare Pity Me!: Natalie is prone to this, as is Clarisse once people start digging at her motive.
  • Exact Words: The Sergeant is fond of this, such as when he tells the remaining mock-rounders that the other previous participants have gone home. The reality is that they're still in Cartesio - they've just had their memories altered to believe Cartesio is home.
  • Firefighters Are Useless: They have to be told to put out the burning car in the junkyard that contains Moloch's corpse.
  • Gambit Pileup: Week Five. Just...Week Five. To summarize: After receiving the motive, both Franciscus and Olympia start making plans for murder, Franciscus to bring Sakura with him and Olympia to save Seyfried. Franciscus comes across Azura in the park and manages to fight and kill her and dispose of the evidence before returning to the hotel, while Olympia lures Millium to the roof with a forged note and ends up killing Cian as well when she intervenes. Later, after both culprits have been caught, Keith and Natalie convince Dazai to draw out Olympia's execution so that they can try and break into the Lodge. Meanwhile, Oda decides to take matters into his own hands and kills Olympia himself, and is locked up as her replacement for Dazai's execution.
  • Glory Seeker: Clarisse's motive Week 3.
  • He Had a Name: Millium to Dabi in regards to Bakugou.
  • Hotel Hellion: Arguably every last one of the "tourists," but especially Nine and Millium when they flood the hotel with soap bubbles.
  • Human Ladder: Used to reach the cinema sign during the Week 2 mission.
  • I Meant to Do That: How Franciscus reacts after getting himself covered in butter when messing up a puzzle in the Week 2 mission.
  • Innocently Insensitive: Millium can come across as this due to a combination of her young age and Lack of Empathy.
  • I Work Alone: Kino operates this way, stating that they can't be responsible for anyone else's lives.
  • Jerkass: Clarisse.
  • Laser-Guided Amnesia: The player characters from the mock week return as semi-amnesiac NPCs that believe they live and work in the town.
  • Moment Killer: Keith and Natalie's kiss in endgame gets interrupted by multiple characters, starting with Kino doing a golf clap.
  • More Expendable Than You: Keith tries to argue this as why everyone should vote for him instead of Bolin in the sixth trial. Considering the suspect list also includes Natalie and Osomatsu, no one buys it for a second.
  • My Friends... and Zoidberg: For some reason, the Sergeant seems to feel nothing but vehement hatred towards Clarisse, even while he praises the rest of the group’s progress.
  • My Greatest Failure: Clarisse feels this way about her own death.
  • The Nicknamer: Gant and Millium.
  • No Sense of Direction: Nine, and how.
  • It's Personal: How Millium feels about Bakugou's trial. She's completely distrusting of all the culprits, even the ones she was previously on good terms with.
  • Phone Call from the Dead: They contact the living through their choice of jukebox songs, the names used in video game high scores, zooming in on words using a microfiche reader, and the televisions and record players in the record store. They can also only receive communication back through the same medium.
  • The Pollyanna: Sakura.
  • Powers as Programs: After gaining admin rights, the survivors are able to pick and choose powers from all the captives to transfer to themselves.
  • Public Execution: For murder culprits, although characters can choose to skip watching it.
  • Robotic Reveal: Olympia is exposed as a robot during the second trial.
  • Sadistic Choice: In Week 5, when Olympia's programming wouldn't even let her consider not acting on the motive, killing Millium was the only way she could avoid having to face her suspicion and distrust in a trial again.
  • Socially Awkward Hero: Keith.
  • Shot at Dawn: How murder culprits are typically taken out.
  • Skewed Priorities: Kinzie's reaction after Franciscus confesses.
    Kinzie: God, I finally get laid in this hellhole and it's someone working off murder stress!
  • The Stoic: Kino.
  • Stupid Sacrifice: How Nine's murder of Moloch is viewed.
  • Survivor Guilt: Nine's motive for Week 2. Cian also suffers from this.
  • Token Evil Teammate: Clarisse.
  • Token Mini-Moe: Sakura and Millium.
  • Tomato Inthe Mirror: All the visitors, as well as their hostages for the Week 7 motive, are simply AI copies of the originals. The survivor pool takes this surprisingly positively.
  • Torches and Pitchforks: Wielded by the townsfolk during the sixth week's event, when looking for the kidnapped Davis.
  • Troubling Unchildlike Behavior: Millium frequently exhibits this.
  • Tsundere: Natalie can come across as this.
  • Tyke Bomb: Millium, to the horror of half the cast.
  • The Unhug: Franciscus gives Sakura an awkward hug when he finds her crying after discovering her friends from the mock trial round are still trapped in town.
  • Urban Legend Love Life: An innocent comment about Keith and Cian spending the night together leads to constant discussions from the dead side about their multiple partners.
  • Was It All a Lie?: Asked by Sakura and Osomatsu to Franciscus when he confesses to Azura’s murder.
  • Wham Episode: Case 4. Three well-liked victims, two culprits who killed because of their friendships with the youngest characters (in very different ways), and one vigilante killing a culprit only to be executed in her place.
  • Why Did It Have to Be Ghosts?: Millium and Sakura certainly feel this way.
