This article lists down the different terms and phrases used in each episode of the Steins;Gate anime and its definition.
Episode 01: Prologue of the Beginning and the End[]
Term 1: El Psy Kongroo[]
"El Psy Kongroo" is the password that Rintaro Okabe uses whenever he ends a phone conversation pertinent to his mad endeavors. However, it is revealed that these supposed conversations he ends are simply to himself because Rintaro has his phone turned off for them. The phrase itself is a reference to the meme "La Yohasoh Steana," and possibly something related to the real world John Titor's codeword, "Tempus edax rerum," meaning "Time, the devourer of all things." Translated as "Congroo" in most of the Steins;Gate anime localizations, the official English translation of the visual novel romanizes it as "Kongroo", which is the canon translation. This is supported by the video D-Mail in the final episodes coming from the e-mail address "sg-epk@jtk93.x29.jp", where the initial five letters stand for "Steins Gate-El Psy Kongroo".
Term 2: Organization[]
This is Okabe's delusional agency, supposedly a highly secret group who is sought after by many opposing organizations, whose secrets would be vital to radical change, which nobody but Okabe cares for. This is the initial irony to the series, as something initially imaginary becomes all too real...
Term 3: Metal Upa[]
- OOPA, or OOPArt, is an acronym for "Out Of Place Artifact", a supposedly futuristic artifact found in an ancient archaeological site. The very existence of OOPArts might be evidence of time traveling that has happened before.
- 'Oopa' is an alternative spelling for Upa. 'Upa' is considered canon.
Term 4: Alpacaman[]
This alpaca with a man's face is a character of virtual pet video game: a parody of a SEGA Dreamcast video game named "Seaman".
Term 5: Hououin Kyouma[]
The main protagonist of Steins;Gate, Rintaro Okabe, is a self-proclaimed mad scientist and often refers to himself under the alias of Hououin Kyouma, which is also the name he uses to introduce himself to other people. He also uses this alias when browsing @channel. Its literal translation is "Phoenix-Shrine Madness-of-truth." Mayuri Shiina and Itaru Hashida refer to him by the nickname 'Okarin'.
Term 6: The Choice of Steins Gate[]
- The phrase itself is a reference to the meme "La Yohasoh Steana" (which is "the Choice of the World" there), as it is for "El Psy Kongroo".
Term 7: Bit Particle Cannon[]
The Bit Particle Cannon is one of the gadgets that Okabe and Daru made, named "Future Gadgets"; it is nothing more than a laser gun-shaped TV remote control. Its full name is "Future Gadget #1: Bit Particle Cannon".
Term 8: Landlord[]
Yuugo Tennouji, the manager of a small electronics store specializing in Braun tubes (hence, Okabe's nickname to him of "Mr. Braun") and CRT-based televisions, is also the property owner of the apartment where the Future Gadget Lab is situated. It is shown that he does not dislike Okabe, but finds his antics to be very disruptive to the property.
Term 9: Hostage[]
Explained later on in the series, Mayuri is said to be Okabe's hostage. This is because she was traumatized by her grandmother's death to the point where she would visit her grave daily during younger years. One day in 2005, Mayuri reached up towards the sky to a beam of light, and Okabe ran to hold her as he announced that he wouldn't let her go anywhere because she is his hostage—he was afraid she would be taken into the heavens and she would not be with him. It's a non-affectionate way of saying he will never have him leave her if he can help it, and he later develops the persona of Hououin Kyouma to assist in emotionally protecting her, later realizing that this is possibly detrimental to her sense of independence.
Term 10: PhoneWave (name subject to change)[]
Future Gadget #8. This is the full name of the machine used for the initial time travel-related plot in the beginning of the series. When a message is sent by a phone to the other phone connected to the microwave, it activates it remotely. Originally designed to be a remote-controlled microwave, this became the base concept for the time machine later on.
Term 11: Gelbana[]
During experimentation with the PhoneWave (name subject to change), a banana teleports back to its stalk in a green, mushy form, marking the beginning of the time-themed plot.
Term 12: University Forum[]
Both Okabe and Daru are students from Tokyo Denki University, and to acquire academic units, they attend to a seminar on the Akihabara Techno Forum (ATF) at Dai-Building.
Episode 02: Time Travel Paranoia[]
Term 1: SCIENCY[]
SCIENCY (a parody of SCIENCE) is the most famous scientific journal magazine in the world and is the academic journal of the American Association for the Advancement of Science. At the young age of 17, Kurisu Makise's academic paper was published in the magazine's April 2010 issue, making her the youngest person to perform such a feat.
Term 2: Yanabayashi Shrine[]
This is the shrine where Luka Urushibara lives and helps manage.
Term 3: Youtou Samidare[]
Replica of a katana sold at Bukiya replica weapon shop. Okabe bought it for 980 yen, but treats it as if it's a legendary blade.
Term 4: “But he's a guy.”[]
In regards to Luka, talking about all his perfectly feminine qualities... but he's a guy.
Term 5: "Oh-ha~!"[]
Short for "Ohayou" (Good morning), the line is said by Suzuha Amane. The greeting won the grand prize in the buzzwords contest for 2000, a decade ago, and is significant for its horrible out-of-dateness.
Term 6: @channel[]
This is the fictional equivalent to the textboard 2channel. The only mentioned tripcode user is JOHN_TITOR. People that use a name but no tripcode include 'Hououin Kyouma' and 'KuriGohan and Kamehameha'. In the anime, JOHN_TITOR and Hououin Kyouma "age" the threads while KuriGohan "sages" them.
Term 7: JOHN_TITOR[]
According to the BBS, John Titor is a time traveler from the year 2036. The user posts on @channel about a futuristic dystopia leaded by the SERN in 2036.
Term 8: SERN[]
Short for "Société Européenne pour la Recherche Nucléaire". A supposedly evil agency who works closely with particle manipulation, SERN is an anime counterpart to the real world CERN. In the series, SERN becomes the antagonist faction to Okabe and the lab. They are a major ruling force in John Titor's time.
Term 9: Dystopia[]
In reference to John Titor's time, a dystopia is a world that is put into a forced state of peace, but it's just a veiled dictatorship.
Term 10: Grandfather Paradox[]
The theory that if you were to go back in time to kill your biological grandfather, you would be from a parallel universe created by the death of your grandfather, as you would never have existed to begin with.
Term 11: World Line[]
Throughout time as a linear plane, world lines are variations of reality in which details differ from one world line to another. There is a lot of hopping of world lines, so the more times world lines are traversed, the more varied the reality is; Okabe observes how one D-Mail can change the whole nature of the city of Akihabara. The % of fluctuation can be tracked by the Divergence Meter, and universal events of world lines within ranges of 1% variation are tethered to outcomes governed by attractor fields.
Term 12: IBN-5100[]
An IBN-5100.
An old computer developed by IBN, the in-series IBM, the IBN-5100 is the in-universe equivalent of the IBM-5100. It is a computer made in 1975 that runs very simple coding that is disregarded in future computer models, causing a very short stock to have ever been produced. This apparently is imperative to the use of a time machine, as said by John Titor.
Term 13: Mayushii NyanNyan[]
Mayuri has a part-time position at MayQueen+Nyan² as a catgirl maid, where they all say "nyan~" at the end of their sentences.
Term 14: Forbidden Secret Technique[]
Faris' ancient technique called "Through Shoulder". Her mention of training at the Guiana Highlands is a reference to Mobile Fighter G Gundam Episode 18.
Episode 03: Parallel Process Paranoia[]
Term 1: HENTAI[]
In Japanese, means 'pervert.' Kurisu uses this quite often for Daru. He insists that he is not a pervert, but a perverted gentleman. Pervert gentleman is a @channel meme for a harmless, mannerly pervert.
Term 2: Christina (Kurisu-tina)[]
Another name given to Kurisu by Okabe. He teases her with this name because it is slightly awkward—it is a continent-neutral name of American and Japanese origin. This is because she has been studying in America, and thought that it would be more suited for his 'international conspiracy' delusions. Other conspiracy-related women include Sara, Claudia, and Simone.
Term 3: Lab Mems (Laboratory Members)[]
The members of the "Future Gadget Laboratory"; Okabe formally inducts each one personally.
Term 4: The Zombie[]
One of the many names given to Kurisu by Okabe, due to seeing her dip her finger into a gelbana and taste its contents for analysis. One could suggest that he enjoys teasing her. From Okabe's perspective, this name is retroactively fitting as she was, in a sense, "resurrected" after being stabbed.
Term 5: Time Machine[]
Unlike traditional time machines, the PhoneWave (name subject to change) is only capable of sending a small amount of data as text back into the past; any larger object sent back would become torn apart at the molecular level (hence the gelbanas).
Term 6: Shining Finger[]
- Trivia: The voice actor of Daru had shouted "Shining Finger!" in Mobile Fighter G Gundam.
Term 7: Sanbo[]
Name of a beef bowl (gyuudon) stand in Akihabara. Being known as Akihabara geeks' favorite, it even has its own Japanese Wikipedia entry. No cell phones, no headphones, and no questions are the rules of the shop.
Term 8: LHC (Large Hadron Collider)[]
This is a device used by both real-world CERN and fictional SERN to collide atoms in an attempt to create extreme forces of energy for scientific research. It's the scientific way of "knocking things together until something interesting happens," including generation of a micro-black hole. It runs underground in a ring. In Steins;Gate, the black holes it generates are used to send people and information back through time.
Term 9: Canned Oden[]
In Japan, there are vending machines nearly everywhere for convenience. This does not only include drinks, but quick soup as well; canned oden is a local specialty of Akihabara.
Term 10: RaiNet Sausage[]
Merchandise of the fictional anime series RaiNet Kakeru.
Term 11: "Human is dead, mismatch"[]
During Daru's investigation, a search on missing persons in SERN's database shows articles involving particular test subjects being transported back in time and torn apart at the molecular level; each subject this happens to has their file branded with this phrase.
Episode 04: Interpreter Rendezvous[]
Term 1: Faris NyanNyan[]
Pink haired girl, inheritant of Akihabara. She works in the same maid cafe as Mayuri and is a friend of Daru and Okarin. Daru looks up to her as the only 3D woman with a 2D soul. She often ends her sentences with "nya~" And wears cat ears (as they appear to be). These are all because of her personality of wanting to act like a cat.
Term 2: RaiNet Kakeru[]
Fictional anime series. The story of 13 episodes is introduced in the Steins;Gate visual novel. The story revolves around an elementary-school hero named Kakeru who fights online battles against evil hackers, with his friend Kirari, and his legendary Monster Program called Upa.
Term 3: Nae Tennouji[]
The docile only daughter of Yuugo Tennouji. She treats Mayuri as her older sister, and when the two meet, they often say "Tutturu" at the same time. She really loves her father and is frightened by Daru and Okabe.
Term 4: "I'm a full-fledged soldier"[]
"I'm a grown-up and a soldier" is the subber's mistranslation.
Term 5: Stardust Handshake[]
Something that Mayuri does sometimes, she looks to the sky and places her hand towards the sun. She's done this since her grandmother died.
Term 6: Faris Cup[]
In the maid café, there is a tournament for RaiNet AccessBattlers, a computer-themed boardgame in which the winner gets to request Faris do anything for them. RNAB is considered to be an arranged version of german boardgame Geister!.
Term 7: G-BACK[]
Okabe's strategy of winning his match RaiNet AccessBattlers against Faris. As their agreement was for Faris to tell Okabe what she knew about the IBN-5100 if Okabe joined her in a match, G-Back, or 自爆 (pronounced "jibaku", translated as "suicide-bombing"), ensures that their game ends quickly.
Episode 05: Starmine Rendezvous[]
Term 1: Your Chest is Getting Hot, Isn't It?[]

Term 3: Fireworks[]
A device containing gunpowder and other combustible chemicals that causes a spectacular explosion when ignited, used typically for display or in celebrations. The significance of this is that Suzuha, being from the dystopian future, has never actually seen them before, as all types of explosions she is familiar with have caused her and her allies grief.
Term 4: Lab Coat[]
Token item of clothing for any scientist.
Term 5: Virus Card[]
A card piece used in the imaginary board game Rai-net Access Battlers. Player loses when they capture four enemy Virus cards.

Term 7: Z-Program[]
The series of experiments SERN is performing at the LHC, using the particle accelerator to transport hopeful people back through time.
Term 8: Lifter[]
A triangular flight device that achieves lift by ionizing air molecules, forcing them through its central electromagnetic axis. It functions as a part of the phone-microwave/time-machine in the form of a 42" cathode ray tube (CRT) television, coincidentally placed beneath the floor of the Future Gadget Lab directly under the microwave.
Term 9: Jellyman's Report[]
The anonymous writer of the SERN time-travel reports involving "mismatched" individuals. Or perhaps named because these "mismatched" individuals listed in these reports have all turned to jelly (gel).
Term 10: Laegjarn's Chest[]
Also known as Pandora's Box. Okabe used this to name the Future Gadget Lab's operation that aims to extract information from SERN's computers.
Term 11: Singular Point[]
A point in time and space selected for existing. Once you pass the point, the functions of time and space are switched. In other words, your time is stretched eternally and you can't escape from the point.
Episode 06: Butterfly Effect's Divergence[]
Term 1: Round-Table Meeting[]
A term meaning that members of a group will equally discuss a subject as peers to solve a problem or examine as situation - their table is rectangle, so it's funny. A reference to Arthurian Legend.
Term 2: Nostalgia Drive (Nostalgic Journey that Crosses Over Time)[]
Nostalgia Drive is a fancy term Okabe coined for the e-mails that they plan to send back in time. Because of his unusual naming sense, his suggestion was rejected by majority vote, and Kurisu's suggestion — D-Mail — ends up being chosen as the term to be used for subsequent experiments.
Term 3: The Mail that Leapt Through Time[]
This is Daru's suggestion for a name that would describe the e-mails they send back in time. The phrase is in fact a reference to the movie "The Girl Who Leapt Through Time", a story of a girl who is able to travel back in time. The movie is sad.
Term 4: D-Mail[]
Kurisu's suggestion for the term to be used for the messages they send back in time. It is a shortcut of Mayuri's suggestion "DeLorean Mail" and it eventually becomes the "official" term the Future Gadget Lab would use to pertain to the messages. DeLorean is a reference to the Back to the Future movie series, wherein the car used by the main characters is a DeLorean DMC-12.
Term 5: Operation Urd (Norn of the Past)[]
Operation Urd pertains to the experiment which attempts to revitalize the project that involves sending messages back in time. Urd comes from the Norse Goddess of the same name who governs the past; she also has two sisters named Verthandi and Skuld. Of course, Okabe was the one who created the name.
Term 6: Kerr Black Hole[]
This is a black hole that spins; most black holes do not have an axis, as they 'suck in' all matter and space, practically folding in on themselves (not to be confused with collapsing). A Kerr Black Hole rotates on its axis as it pulls anything, but rather than puling matter immediately into it, it can somewhat orbit matter around itself infinitely. This is why it is associated with time travel, as supposedly the more you can approach the speed of light, the slower time becomes - if you were to somehow go faster than light, time could be transversed in either direction.
Term 7: Event Horizon[]
Basically, the "point of no return" around a black hole - nothing can escape the gravitational pull, not even light. This is the location in which nothing can affect anything outside.
Term 8: My Favorite Right Arm (Dependence on One's Right Arm)[]
In other words, something that cannot be replaced and is absolutely vital. A term to refer to an irreplaceable and useful ally.
Term 9: Super Hacka[]
Daru, self proclaimed "Super Hacker", is called "Super Hacka" by Okabe. The western meme equivalent would be to refer to an internet hacker as 'hax0r', which can be further leetspeaked.
Term 10: Yuri Field[]
Term used by Okabe to describe Mayuri comforting Kurisu when she bumped her head. Yuri is a Japanese term usually reserved for Anime and Manga that roughly translates to "Girls Love" or a sexual/romantic lesbian relationship between two female characters.
Episode 07: Divergence Singularity[]
Term 1: Phone Microwave Second Edition Version 1.03[]
The latest version of Okabe and Itaru's Phone Microwave (temporary name), with name invented by the latter. Unlike the previous version, it can now send messages from any phone using the cellphone that comes with the Phone Microwave. However, it can no longer cook anything, even gel bananas.
Term 2: Celebrity Seventeen[]
Kurisu is given yet another nickname by Okabe in this episode: Celeb 17 (or Celebrity 17). It pertains to Kurisu's well-to-do lifestyle (living in a hotel using her parents' money) that is unusual for someone of her age. Kurisu points out that she is eighteen, not seventeen...
Term 3: Sweets[]
Term 4: Upa Cushion[]
One of the many items that can be found inside the Future Gadget Lab, the Upa Cushion is recommended by Mayuri for people who feel down or is stressed. According to her, a quick squeeze of the soft plush doll from the Rai-Net Kakeru merchandise is enough to soothe one's mind.
Term 5: Tsundere[]
Roughly translates to "hot and cold". It is a term used to describe people (especially women) who act hostile or cold (tsun) and often later show their warm and loving side (dere) towards people of the opposite sex. Example: "It's not like I wanted to see you or anything."
Episode 08: Chaos Theory Homeostasis I[]

Term 4: Low-angler[]
A certain photographer that targets cosplayer's lower part or even from below and photograph them.
Term 5: Venomous Radiowave[]
TBA
Term 6: Pocket Pager[]
Luka Urushibara(the guy more feminine than any woman) wants to send a D-Mail to his mother in order to change his gender, but at the time of his mother mobile phones didn't exist yet. However, there were pagers. Daru converted the message to numbers and sent it to Luka's mother using the "PhoneWave (name subject to change)". The message was: "Eat vegetables for a healthy child" because Luka believed that if a pregnant woman ate a lot of vegetables, she would have a girl, and if meat - a boy.
Term 7: EatVegitablesForAHealthyChild[]
Possibly a typographical error for "Eat vegetables for a healthy child". This was the mail sent by Luka Urushibara to her mother using Okabe's D-Mail invention to change her gender (from being male to a female). However, due to it's limitations, as tested by Kurisu Makisw, spaces between words have been omitted to send the full message to Luka's mother's pager (cellphones weren't so popular in the time of Luka's mother's pregnancy).
Term 8: "Home again, home again, jiggity-jig."[]
In the dubbed version, Mr. Braun speaks this phrase as he steps out of the delivery truck. It is a direct reference to 'Blade Runner'; one of J. F. Sebastian's 'toys' says 'Home again, home again, jiggity-jig' when he enters his apartment.
Episode 09: Chaos Theory Homeostasis II[]
Term 1: Cosplay[]
Cosplay is a type of performance art where participants wear costumes to represent a specific character. Mayuri's hobby is creating costumes for cosplay, and she gets excited at the opportunity to involve any of her fellow lab members. Kurisu Makise occasionally hints at her interest, as she is what many would call a 'Closet Otaku', but she is always quick to brush it off.
Term 2: Physical Time Travel[]
Refers to the hypothetical theory of traveling time and space with the traveller's physical body. For example, Okabe, when he uses the Time Leap, travels with his mind and sends the information to the Okabe on the other world line altering the latter's memories. But if he used the methods of physical time travel (which is proven impossible in any terms) the Okabe from the original world line would vanish because his body (or to be exact, his very existence) would have already left that world line.
Term 3: Gel-Okabe[]
TBA
Term 4: Neler (@channeler)[]
TBA
Term 5: Butterfly Effect[]

Term 8: Nakano[]
TBA
Term 9: 'Could you be more of a Wesley?' (Dub)[]
Owing to Okabe's usual stubbornness, Kurisu calls him a 'Wesley'. This is a reference to Wesley Crusher from Star Trek TNG; furthermore Okabe's comments afterwords when he calls Kurisu 'Madame Next Gen' and says 'Going too boldly, I am?' at her retort, as well as calling her Nurse Chapel (who was portrayed by Majel Roddenberry, wife of Gene Wesley Roddenberry, creator of Star Trek), all pay homage to Star Trek and TNG as well. There is also a subtle hint of foreshadowing with this clever quip; Wesley was often considered infantile and annoying (like Okabe), and yet he served as a 'deux ex machina' of sorts on multiple occasions in TNG - this direct analogy belies Okabe's role as the 'savior' (as mentioned previously by John Titor).
Episode 10: Chaos Theory Homeostasis III[]
Term 1: BlooTu (Blood Tune: The Animation)[]
TBA
Term 2: Mongolian blue spot (Mole)[]

Term 2: Time Leap[]
A modification made to the "PhoneWave (name subject to change)", allows Okabe to send his current memories to himself in the past without changing world lines. This is highly used and specified in the series of deaths of Mayuri, where Okabe tries to prevent her death by using the "time leap". He goes back at least three hours before the time of Mayuri's previous death but his efforts turned out to be futile. He continues to use the Time Leap in a desperate attempt to save Mayuri but ends up being unable to prevent her death countless times.
Term 3: Operation Verthandi ("Norn of the Present")[]
The operation to create the Time Leap Machine. Verthandi is a figure of Norse Mythology, and is also known as the "Goddess of Fate." she is often referred to along with the beings Urðr and Skuld, (also terms thrown around by Okabe) and the three of them were tasked with deciding the fates of people.

Episode 12: Dogma in Ergosphere[]
Term 1: Time Leap Machine[]
A modification made to the "PhoneWave (name subject to change)", allowing the user to send his current memories to himself in the past, it's not the same as the D-Mail because Okabe stays in the same world line when he uses this.

Term 1: Ark Rewrite[]
The journal where Moeka works (fictional).
Term 2: My Fork[]
The writers of this show have a tendency to develop highly complex story-lines, and then only hint to them in the actual main story. As a way for Kurisu Makise to understand that Okabe time-leaped back a few hours prior to Mayuri's death, she tells Okabe that she needs a "fork" to go with her "spoon" in the present, so that when he time-leaps back, she'll believe that Okabe came back from the future to save Mayuri. What was revealed in one of the later visual novels is that the spoon was a gift from Kurisu's father, a figure who spent much of her life psychologically abusing her. According to her, the spoon is a way of telling herself that her father really does love her.
Term 3: Rounders[]
Sleeper agents and assassins that informally work for SERN. On the paper, they are a completely different and independent organization. They are organized, but independent.

Term 6: Alpha World Line, Beta World Line[]
By using the first D-Mail to undo Kurisu Makise's death after seeing that she had been stabbed and was bathing in a pool of blood, Okabe created another world line, known as the Alpha World Line, which differs from his original world line. The previous Beta World Line is Okabe's "original" world line and crossing the 1% divergence barrier is the only way to get back there.

Future Gadget #204.
Term 3: Suzu Hashida[]
After Suzuha Amane travels back to 1975 in order to obtain an IBN 5100, she changes her name to Suzu Hashida. This is because Suzuha traveled back in the time machine that Daru tried to repair, but did not repair successfully, causing her to obtain amnesia as soon as she arrived in 1975. Hashida Suzu was the only thing she could remember, so she called herself that until she regained her memories in 2000.

Episode 17: Made in Complex[]
Term 1: Attractor Field[]
The invisible power that governs the events of world lines with a divergence number within 1% of universal historical changes. Despite relatively minor changes in history, every world line will obey the same destiny, such as the deaths of certain individuals at certain times, by any means. Okabe is currently trapped in a world line governed by the Alpha Attractor Field (0%<α<1%), in which Mayuri is governed by the attractor field to die within a certain time frame. Okabe needs to cause a massively significant change in history to break the 1% divergence barrier to reach the Beta Attractor Field (1% < β < 2%), in which Mayuri will not die. He was originally moved to a Alpha world line through his D-Mails.

Term 4: Mayuri's Dreams[]
Mayuri has dreams in which she always dies in all sorts of horrible ways. showing that she remembers every time she died when Okarin was trying to save her from the inevitable death that awaited her in the Alpha world line.

Term 2: 1% Barrier[]
Okabe needed the Divergence Meter to read a value greater than 1% because it would mean that he is back to a Beta World Line. On the Alpha World Line, it is <1% and Mayuri keeps on dying on those world lines no matter how hard Okabe tries to prevent her death.
Term 3: Relativity Theory[]
The most famous Einstein's theory, Kurisu uses it metaphorically to say time can pass at different speeds.

Term 2: Steins Gate[]
A world line that resides between the Alpha and Beta Attractor Fields. Because of this, it is exempt from events that occur in either field. Its divergence is known to be 1.048596%. Since it is not affected by either attractor fields, Mayuri and Kurisu do not die and neither SERN dystopia or WW3 happen.
Term 3: Serious Paradox[]
Suzuha Amane warns Okabe that if he sees his past self, he'll cause a major time paradox. This could be related to tearing the fabrics of time and space.
Term 4: Doctor Nakabachi[]
He is Kurisu Makise's father and is possibly the one who stabbed her in Episode 01. In previous episodes, it has been revealed by Kurisu that they have a horrible relationship due to her superior intelligence and his jealousy for her. He also stole the time machine paper that Kurisu wrote in the beginning, published it under his name only, and brought it to Russia where a race to create a time machine began.
Term 5: Movie Mail[]
In Episode 01, right after hiding from Kurisu, Okabe receives a strange video message, which he can't view. In Episode 23, Okabe finds out that he can view the message after failing to rescue Kurisu once. It turns out that the message was created by Okabe himself 15 years in the future.
Term 6: C204[]
On the Beta World Line, Okabe creates a time machine in 2025. It has the ability to travel both forward and backward through time, and Suzuha Amane arrives in Akihabara in 2010 in this time machine. With the goal of stopping World War III, she travels back in time to recruit Okabe to save Kurisu. Okabe names this machine C204, the "C" refering to Christina (Kurisu); her death on the Beta World Line and his desire to save her is the driving force behind his creation of the time machine.
This is also a reference to the "real world" John Titor, who claims that his time machine is called the C204.
Term 7: Operation Skuld ("The Goddess that Governs the Future" Operation)[]
The operation involves Okabe seeing Kurisu lying in a pool of blood, destroying the document about time machines (which Kurisu wrote), and prevent World War III. Okabe has to trick himself into thinking that Kurisu is actually dead, and he has to trick the world itself (Okabe being its observer due to Reading Steiner) in order to save her.
Episode 24: The Prologue Begins With the End[]
Term 1: Cyalume Saber[]
Future Gadget #6, 'Cyalume Saber'. It contains a red liquid that Okabe will later use to fool his past self into thinking it is the blood of Kurisu Makise. Unfortunately it hasn't been used in such a long time that the air had caused the red liquid to solidify.
Term 2: Upa[]
Upas are those spherical toys that look like bears. They are from the fictional RaiNet Kakeru series. Okabe bought the Metal Upa for Mayuri in the first episode of the series. This is significant because the Metal Upa was dropped by Mayuri on one of the Beta World Lines and later picked up by Kurisu Makise who placed it in the envelope with her time travel thesis. The thesis was to be stolen by Dr. Nakabachi and taken to Russia, but on the other world lines, the Metal Upa set off the metal detector, thus saving the paper from an on-board fire. By buying the Metal Upa, Okabe's counterpart in the current time line bought Mayuri a Green Upa instead of a Metal Upa so that it would be picked up by Kurisu later on. Since the Green Upa is not made of metal, the metal detector wasn't set off and the thesis was burned in the plane, preventing World War III.
