Revenge of Time Clam

The Revenge of Time Clam event, also known as Blood Clam who leapt in the Steam port, is a rare event that more or less serves as a glorified crash handler in case logic errors occur. As the circumstances for obtaining this event aren't intended to arise, this event doesn't unlock anything. In fact, after the event ends the loop is terminated entirely and the player will be booted back to the Setup screen as if nothing had happened.

The player will receive no experience points from a loop terminated by this event regardless of how the loop had gone up until that point. Furthermore, any progress made in regards to levels, skill acquisition, etc. during that loop will be undone due to the universe's oblivion beyond oblivion. Fortunately it's nigh impossible to stumble into this event unintentionally, and if someone were to manage it they were likely trying to find a creative way to lose in the first place.

Obtaining the Event
In order to see the Revenge of Time Clam event, the AI must encounter a fatal logic error during the discussion phase. To do this, the player must create a paradox wherein humans can be declared Definite Enemies, Gnosia can be declared Definite Humans, or something else inexplicable and unresolvable occurs. This can be achieved in any number of ways, but must involve the presence of an Engineer or Doctor. Specifically, the player must play as one of these two roles and fail to declare their role on Day 1 after a false claim has been made.

While the specifics of the scenarios can vary, the two overall methodologies are:

Doctor Method

 * 1) The player is the Doctor and does not come forward with their role when prompted.
 * 2) Only one false Doctor claim is made.
 * 3) Someone judges the false Doctor to be a Definite Human.
 * 4) Contradictions arise over the course of the loop until a paradox occurs.

Engineer Method

 * 1) The player is the Engineer and does not come forward with their role when prompted.
 * 2) Only one false Engineer claim is made.
 * 3) Someone judges the false Engineer to be a Definite Human.
 * 4) The player investigates and eliminates the Bug at night.
 * 5) When the fake Engineer gives their report, they report not having investigated the Bug.
 * 6) Alternatively, contradictions simply pile up as in the Doctor method until the game can no longer proceed.

Tips

 * It's easier to get this event once you've reached the postgame as completing the game gives you options that allow you to "savescum" until you've identified the Bug (Engineer Method) or otherwise made things play out in your favor.
 * Setting the number of crew members and Gnosia to a high number will give you more wiggle room for contradictions to occur.
 * If you're using the Engineer Method, disable the AC Follower. If you're using the Doctor Method, you may want to disable the Bug as well. These roles can both lie, which can make it difficult to achieve the goal of only one false claim for your role coming forward.
 * If the Bug is enabled, request that the Engineer/Doctor (whichever role you aren't using) step forward before doing anything else. This should lure the Bug into fake claiming that role and ensuring that only one fake claim is made for your role.

Event Description
After a paradox occurs, the player will suddenly be unable to act, only able to select Wait and See. One of the crew members will suddenly speak up and spew gibberish while using a "skill" called "Revenge of Time Clam". Another character will join in, prompting the player character to question what's going on. LeVi will chime in to announce that the ship is experiencing strain on its yummy noodle bing-bong, confusing the player character further.

Raqio will then appear, even if they were put into cold sleep or otherwise eliminated. They (sort of) explain that due to an error in calculations, "the universe kit must've gone funny". Two more Raqios then manifest and begin laughing maniacally, at which point a system message appears informing you that you've broken reality by failing to claim your role promptly.

The universe is irreparably destroyed, and the player and Setsu move on to their next loop.

Trivia

 * Yuriko is the only character who speaks normally during this event, expressing awareness that the universe is coming to an end.
 * This event can be obtained a limitless number of times like standard loop endings.
 * Though Bugs also end the universe when they win, but unlike this event you'll still retain any progress you made in regards to levels, skills, etc. It can be a fun experience to use the Engineer method to safely eliminate the Bug and save the universe... only to immediately end the universe yourself as a result.
 * The game vaguely alludes to the existence of this event, warning you in numerous places that it's dangerous not to claim your role:
 * The in-game How to Play guide admits that you can refuse to come forward when a false claim is made, but ominously proclaims that if you do so "You may be in for trouble."
 * Reveal Own Role's description states that if you don't use it after a false claim, "things can get really difficult for you later!"
 * Due to a visual glitch, Blood Clam who leapt has text cutoff, with the full name of the command being Blood Clam who leapt through time.
 * This name is a reference to the time-travel novel, The Girl Who Leapt Through Time.
