Steins;Gate/Characters
Rintaro Okabe
Voiced by: Mamoru Miyano
The protagonist, an 18-year-old 1st-year college student and leader of the Future Gadget Laboratory. He is the first in the series to be conscious of the timeline changes, an ability he calls "Reading Steiner".
- Always Save the Girl: He goes through many timelines to save Mayuri, although it is implied that he ultimately chooses Kurisu.
- Catch Phrase: "I am mad scientist!", "This is the choice of Stein's Gate!", "El Psy Congroo", among others.
- Despair Event Horizon: Burst out crying after countless time-leaps in order to save Mayuri with no success.
- The Determinator
- Do Not Call Me Paul: "Call me Hououin Kyouma!"
- Evil Laugh: Quite good at it, and hilarious too!
- Eyes of Gold
- Fate Worse Than Death: In 2025 of Alpha timeline, he's captured by the Rounders and gruesomely tortured to death.
- Future Badass: Alpha timeline, where he leads an international terrrorist group against SERN in the future and Beta timeline, where he creates the time machine.
- Get a Hold of Yourself, Man!: Delivered by Mayuri.
- The Gift: Reading Steiner.
- Gratuitous English: Uses it constantly. Along with Gratuitous German.
- In-Series Nickname: Refers to himself as "Hououin Kyouma". Mayuri and Daru call him "Okarin".
- Jerk with a Heart of Gold
- La Résistance
- Large Ham: When he's acting out his Hououin Kyouma persona, he tends to be very loud and theatrical. When Okabe himself shines through, he's inclined towards gloominess and is actually fairly mellow.
- Love Makes You Crazy
- Mad Scientist: Or, as he prefers to call himself, the Crazy Mad Scientist "Hououin Kyouma".
- The Nicknamer: Enjoys giving other people nicknames based on their deeds, except Mayuri, who already coined her own nickname "Mayushii".
- Phrase Catcher: "You're the last person I want to hear that from."
- Screw Destiny
- Seen It All
- Tsundere: He's not as blatant as Kurisu, but he fills this category as well, as is cheerfully pointed out by Mayuri.
- Would Hit a Girl: Hits Moeka hard when he believes it's the only way to save Mayuri.
Mayuri Shiina
Voiced by: Kana Hanazawa
A 16-year-old high school student and Okabe's childhood friend. She works at May Queen and is also a cosplay designer. She's killed in most timelines, often by Moeka.
- Break the Cutie: Very much so.
- Catch Phrase: Her "Tuturu~" whenever she greets someone.
- Cat Smile: Justified that she work as a waitress in a cat girl cafe.
- Childhood Friends: With Okabe.
- Cosplay Otaku Girl: She loves cosplay, but is only interested in making the costumes and having others wear them.
- The Ditz: She tends not to understand anything that's going on in the lab and, unlike Daru, doesn't seem to get it even after having it simplified. When Mayuri says that one of the names Kurisu came up for to describe what they're doing was too complicated, Kurisu nearly says it doesn't count because Mayuri is dumb, which Okabe catches her on.
- Gamer Chick: She's a big fan of RaiNet, but there's no indication that she's actually any good at it. Rather, she just thinks the mascot is adorable.
- Green Eyes
- In-Series Nickname: "Mayushii", a nickname she gives to herself.
- Incorruptible Pure Pureness: She's a pretty mild example: while Okabe and Daru are all gung-ho about hacking into SERN and other dubious activities, Mayuri disapproves even when it's clear that SERN is up to some pretty shady business.
- Kill the Cutie: Many times. Okabe went through many timelines to try to save her, but the few times he did ended badly for Kurisu.
- Nice Hat: Almost always wears a wide brimmed, frilly looking blue hat.
- Smarter Than You Look: Despite what her ditzy mannerisms might suggest, she can be very insightful.
- Third Person Person: Always refers to herself as Mayushii instead of using a pronoun.
- Unlucky Childhood Friend: Ambiguous, but implied in the true ending.
- Your Mileage May Vary. There are little to no romantic/sexual implications between Okabe and Mayuri whereas there are plenty of examples between Okabe and the other female characters, including Ruka.
Kurisu Makise
Voiced by: Asami Imai
An 18-year-old Teen Genius killed in the initial timeline, only to reappear alive and well in another. She later becomes a lab member, and starts working along with Daru in the creation of new gadgets. In the final chapters, Okabe has to save her from being stabbed to death by her father. She falls in love with Okabe, and kisses him after listening to his confession.
- Abusive Parents/Parental Neglect: Kurisu's father keeps a distance from her, downright refusing to see her. Justified in that he is Dr. Nakabachi.
- Adaptation Dye Job: Kurisu's hair is brown in the original visual novel, but has red hair in the anime.
- Blue Eyes
- Broken Bird
- Captain Ersatz: Looks very similar to Tsubaki Yayoi (anime only) in terms of appearance, she even has the same voice actor to boot!
- Closet Geek
- Cry Cute: In episode 5, after Okabe, already irate at losing a board game with her, yells at her for calling him by his real name, and then calling her "Christina".
- Guilty Pleasure: Posting on 2channel, dropping internet slang, just to name a few. Often becomes embarrassed when Daru and Okarin points them out.
- In-Series Nickname: Multiple nicknames used by Okabe, mainly "Christina". There's also "The Zombie" or simply "Assistant". There was also the short lived "Celebrity 7" or "Celeb-7".
- Intelligence Equals Isolation: Prior to knowing Okabe and co., though not so much she isolates herself as others isolate her. Her dad no longer wants to see her after she disproved his theory at the age of eleven, and her co-workers are mostly scientist with big egos, who are jealous of her due to her young age. In one fairly comical scene between herself, Daru and Okabe, she unintentionally reveals she's a virgin and has never been on a date.
- Lethal Chef: Her apple pie is considered a lethal weapon.
- My Name Is Not CHRISTINA!
- Omnidisciplinary Scientist: Is a neuroscientist, but is apparently well-versed enough in theoretical physics to conceptualize and build a time machine.
- Pettanko: Maybe only in the anime. In the visual novel, there's a couple of scenes showing she's not that flat-chested.
- Red Headed Heroine
- Sobriquet: "Mother of Time Machine", in the future where SERN rules.
- Teen Genius: From an early age, she studied math and science like crazy at the expense of everything else, which has left her a more respected scientist than her father, even though she's seventeen when the story starts.
- Took a Level in Badass: She's one of the 2 guest characters in the 2D fighting game Phantom Breaker, and is the only normal human, but she can fight an even match against superpowered adversaries using lab gadgets. It should be noted that she's among the only 2 characters who have 2 supers.
- Tsundere: A hilariously stereotypical one, at that. Lampshaded by Daru, much to her dismay and denial.
- Yandere: Just... Listen to this drama CD.
- You Have Outlived Your Usefulness: Implied to be her fate at SERN's hands, after she completed the time machine for them in 2034.
Itaru Hashida
Voiced by: Tomokazu Seki
Okabe's best friend and a hacker. He's Suzuha's father, but he isn't aware of this fact until she leaves.
- Big Fun: He's a big, fat and somewhat messy guy, but he helps keep the mood going with his generally laid back personality.
- Future Badass: He leads the terrorist organization against SERN after Okabe dies in 2025, and manages to create another time machine (it's not complete like Kurisu's though), which he leaves for his daughter.
- In-Series Nickname: Everybody calls him "Daru".
- Lovable Sex Maniac: Whenever a girl lets loose an Accidental Innuendo, he'll ask them to repeat it. He also insists on having all the technical stuff explained to him in terms of eroge.
- Luke, I Am Your Father: He's Suzuha's.
- Megane
- My Name Is Not Hakka: It's HACKER!
- Nice Hat
- Otaku: 2-D girls are the only girls for him! Except when they aren't, of course.
Ruka Urushibara
Voiced by: Yuu Kobayashi
Mayuri's classmate, a crossdresser boy who works at his family's shrine. His family owns the IBN 5100 left by Suzu Hashida, but loses it in following timelines after he sends his D-Mail and becomes a girl. He is the second character that remembers things from other timelines.
- A-Cup Angst: Gets this when he turns into a girl but retains the same appearance.
- Bokukko
- Cry Cute: Even cuter than Kurisu!
- Dude Looks Like a Lady: "But... he's a guy!"
- Gender Bender: After sending his D-Mail, he becomes a full-fledged female in the following timelines.
- Hair Decorations: "But... he's a guy!"
- In-Series Nickname: "Rukako", used by Okabe.
- Miko: Despite being male, Luka seems to work as the shrine miko anyway, which doesn't help when it comes to being recognized as male.
- Pettanko: Keeps the same bust size even after changing gender.
- Purple Eyes
- Shrinking Violet: He's very shy and quiet, so Okabe seems to have taken it upon himself to give him manliness lessons by practice swinging a fake sword.
- Single-Target Sexuality: Okabe. Even when he was male and told Okabe he didn't like him that way, there are still hints dropped that he does have at least a crush on him. He didn't get a lot of screen time to show any interest in anybody else.
- Transgender: Why she sends her D-Mail.
Moeka Kiryuu
Voiced by: Saori Goto
A silent young woman who prefers to communicate through her cellphone. Seems to be searching the IBN 5100 as well. She works for a man named FB, and will do anything he orders.
- Bitch in Sheep's Clothing
- Driven to Suicide: Twice. The first was four years prior, only to be stopped when she received FB's first message. The second is on the timeline after Ruka undoes the effects of her D-Mail, as she hasn't received any messages from FB.
- The Glasses Come Off: She's missing her glasses when she reveals to the lab members that she's an SERN agent.
- In-Series Nickname: Rintaro calls her "Shining Finger".
- Meganekko: Her glasses help her look withdrawn and timid.
- The Mole: She joins the lab group largely because she's also looking for the IBN 5100, and once she has everything she needs, she leads a team to capture them all apart from Mayuri, who is marked for death instead.
- Perpetual Frowner: Her life is pretty empty, so she always looks essentially expressionless and depressed. When in the lab for the first time, she seems intrigued by these people, but since she looks so emotionless, it's a little hard to tell.
- The Quiet One: She hates having to speak, but when using mail, she's a real chatterbox to the point where the frequency of her messages really irritates Okabe. She begins talking just a bit more frequently by the time the movie comes around.
- Rei Ayanami Expy: Has some shades.
- Shrinking Violet
- Tall, Dark and Bishoujo
- Villainous Breakdown: Driven to Suicide after FB drops her for failing her mission in the timeline where Ruka undoes the effects of her D-Mail, typing on her cell phone nothing but endless strings of "FB".
Suzuha Amane
Voiced by: Yukari Tamura
A teen girl who works at Mr. Braun shop. Likes to ride her bicycle and gets along very well with Nae, Mr. Braun's daughter. She's actually a member of the future La Résistance against SERN, and has traveled to past to meet with her father Itaru, a creator of the time traveling machine. She then travels back to The Seventies and leaves the IBN 5100 in the Urushibara shrine.

Faris Nyannyan/Rumiho Akiha
Voiced by: Halko Momoi
Mayuri's coworker at the May Queen Cafe and the owner. After she sends her D-Mail, Akihabara loses everything related with moe culture as her father is still alive. She also is the first character to remember memories from other timelines apart from Okabe and Ruka.

- Girlish Pigtails
- The Ojou: She's extremely wealthy and has quite the wealthy lifestyle, though she keeps this hidden from most people.
- Rose-Haired Girl: Her energetic, playful attitude and pink hair matching is quite possibly not a coincidence at all: as much as she loves anime culture and considering the otherwise natural-ish hair colors, it could be dyed.
- Spell My Name with an "S": "Faris" is apparently the official spelling, but "Feiris" and "Feyris" also see heavy use.
- Verbal Tic: She even ends her sentences with "-nya".

Appears in the 25th episode: she is a woman whom Rintaro initially mistakes for Suzuha. Actually, she is Suzuha's future mother and Itaru's wife-to-be.
- Significant Double Casting
- Strong Family Resemblance: She looks (and sounds) just like Suzuha without the braids.
- Anime version only. Her appearance in the manga Boukan no Rebellion makes it clear that Suzuha takes after her father there.
