Suzuha Amane

In the Alpha Attractor Field that most of Steins;Gate takes place in, Suzuha Amane (阿万音鈴羽, Amane Suzuha), later known as Suzu Hashida (橋田鈴, Hashida Suzu), is a part-time employee for Yugo Tennouji's (the landlord of Rintaro Okabe's flat) CRT store who is on a search for her father in Akihabara. She enjoys riding her bicycle, appears to be at odds with Kurisu Makise and is a major character in the series.

She is in fact a time traveler from 2036 who, under the guise of John Titor, seeks to prevent SERN, at the command of the Committee of 300, from creating a Time Machine that will lead to a dystopian future. Although she is initially unaware of it, she is the daughter of Itaru Hashida and Yuki Amane.

In the Beta Attractor Field, where most of Steins;Gate 0 takes place in, Suzuha comes from a future ravaged by WWIII with the mission of going back to the day of Kurisu's death so that Rintaro can prevent it and, in doing so, stop WWIII and reach the Steins Gate Worldline.

Appearance
Suzuha's physical attributes include pale toned skin, long brown hair, and a slim profile. She keeps her hair tied up in braids. Her eyes are a bright neon yellow, however, in the anime as well as Steins;Gate 0, their color is significantly toned down, bringing them closer to a dull golden-brown color.

Alpha
In the Alpha Attractor Field, her outfit consists of a blue jacket, black bike shorts, white socks, and black tennis shoes. Under her jacket, she wears a black sport bra. She also allows her braids to fall freely onto her shoulders.

Beta
In the Beta Attractor Field, she initially wears a military combat uniform with a brown holster strapped to her chest, brown gloves and a black bandana tied over her left bicep. 6 months later, she wears a black jacket over a blue turtle neck as well as green cargo pants and black combat boots. She keeps her braids tied up in circles around her ears. Beta Suzuha also appears slightly taller then her Alpha counterpart.

Alpha
A friendly, athletic girl who loves cycling and works part-time at the Braun Tube Workshop below the lab. Suzuha often comes across as overly familiar, but in truth she maintains a carefully measured distance from everyone. When something captures her interest, however, Suzuha's personality changes dramatically and she becomes aggressive and relentless, meaning she is a really straight type of person. She is also perceptive, as shown in her ending when she realized that Rintaro was time leaping.

Suzuha dislikes asking others for help, and will not reveal her own problems to anyone unless absolutely necessary. She also has a tendency to use uncommon or antiquated words in casual conversation.

Suzuha claimed to work with Tennouji because of her interest in Braun Tubes, though she constantly slacks off by maintaining her bicycle whenever her boss is not around.

Due to the dystopian nature of her era, she is not accustomed to most things quite common in the 21st century such as corn, fireworks, and beef bowls and is easily excited to try everything out. This implies the truly cold desolate nature of her era that possibly prevented her from enjoying life.

After she went back in time to 1975 safely thanks to Okabe's D-Mail to prevent Suzuha's suicide in another Alpha world line, she became more wise and mature because of her own mind and physical appearance even ages after going back in time. She was much kind but slightly sternful towards only Shouichi Makise than Yukitaka Akiha and Tennouji because of the former's inflated ego during the meeting between her, Makise and Yukitaka back in 1994 which escalated into an argument with Suzuha and Yukitaka willing to stop researching Time Travel together after Shouichi complicated things for them but in spite of it, she was a positive influence on him when he admits his love to Kurisu indirectly in spite of their strainful relationship between them.

During the anime and somewhat in the game, she has a strong dislike towards Kurisu due to the fact that Kurisu's contribution to the invention of the time machine and her assistance to SERN contributed to a desolate future. When Suzuha hears Kurisu has done something to Rintaro, she turns serious and gets worried for him. In addition, when Rintaro claims to be brainwashed or tortured, Suzuha becomes increasingly worried, truly believing something bad has happened to Rintaro. This implies that Suzuha herself might have had experience with being tortured or that SERN had tortured others.

Despite coming off as very relaxed and lazy, Suzuha actually values the completion of her mission highly. In one of the observed Alpha Worldlines, Suzuha gets amnesia once she travels to 1975. When she recovered from her amnesia in 1999, she was overcome with guilt over not being able to fulfill her mission. The guilt was so overwhelming that over the next year, her mental state progressively worsened until she committed suicide.

Beta
This Suzuha is much less friendly and energetic then her alpha counterpart. A serious and mission driven individual, she shows clear frustration at not being able to complete her mission and truly wants to save humanity from WWIII. As she has strong faith in her goal, Suzuha is even able to threaten to shoot Okabe in an attempt to have him try to save Kurisu and was able to injure him when he tried to stop her and Mayuri from using the Time Machine.

All that being true, she still cares deeply for her friends and comrades. After she was separated from Kagari in 1998, she used up most the Time Machine's fuel to try and locate her. This also applies to her father, Daru. While she is often annoyed by Daru's perverted nature and his lack of progress in his relationship to Yuki, she does care for her father deeply. When it seemed like a brainwashed Kagari might use a knife to attack Daru, Suzuha, despite their previous relationship, threatened to kill her if she hurt him.

After waiting for 6 months for Okabe to change his mind and agree to go with her and being prevented from forcing him to, Suzuha became somewhat disillusioned with her mission. In stark contrast with her Alpha self, Suzuha admitted that a part of her would be happy if she got amnesia, forgot about her mission and lived a normal life in the past.

Her relationship with Yuki is somewhat awkward. She still thinks of Yuki as her mother, but because Yuki is unaware of the group's history with time travel, Suzuha cannot reveal this fact to her. As a result, Suzuha tends to avoid her when possible.

Radio Kaikan
At the start of the story, in the Beta Attractor Field, Suzuha safely lands her time machine on the roof of the Radio Kaikan building. What happens afterwards is not shown, as the world line switches to the Alpha Attractor Field shortly afterwards, in which the device's coordinates are slightly off, causing it to "appear" inside Radio Kaikan's upper floor, damaging itself and the building. Regardless, Suzuha manages to acquire a MTB bike and a phone and seeks employment at the Braun Tube Workshop owned by Yugo Tennouji in order to get close to the Future Gadget Laboratory.

Part-Time Warrior
Rintaro first encounters her when she applies to work part-time at the Braun Tube Workshop. She appears fairly frequently but is often slacking off due to the Braun Tube Workshop's unpopularity. He christens her "Part-Time Warrior", due to her statement that she is a soldier. She forms a close relationship with Nae Tennouji but always glares menacingly at Kurisu Makise whenever she sees her. She believes Kurisu is a SERN conspirator because she is hailed as the "Mother of Time Machines" in 2036, unaware of the fact that Kurisu's co-operation with SERN was probably involuntary. As John Titor, she exchanges mail with Rintaro and posts on @channel, although no one is aware of her identity.

Search for Father
Suzuha attempts to meet her father at a time machine offline meet she knows he will attend. However, this meeting is prevented by an unknowing Rintaro, who prevents Daru from going to the meeting. Unable to meet her father, Suzuha leaves after sending a mail containing the single word "Goodbye" to Rintaro. She uses her time machine to leap to 1975 and obtain the IBN 5100. However, these events change after Rintaro sends a D-Mail so he would pursue Suzuha and prevent her from leaving. She remains in Akihabara, although during this time the time machine is damaged by rain water. Rintaro dubs her Lab Member no. 008 after accidentally telling her about the PhoneWave's existence.

Last Supper
After the completion of the Time Leap Machine, Suzuha attends the celebratory dinner with the other lab members. During the party, they watch a news station report that a terrorist threat caused the train station to close. She quickly realized something terrible is going to happen and leaves the lab. While she is gone, Moeka Kiryu and several Rounders attack the lab and kill Mayuri Shiina. However, Suzuha shows up and defeats all the Rounders. She told Rintaro she had turned on the 42" CRT TV, so the time leap machine is in working condition. She is then trapped in a gun standoff with Moeka, giving Rintaro enough time to use the time leap machine to jump back in time.

Amnesia
After attaining World Line Divergence 0.337187% and using the Time Leap Machine to try and prevent Mayuri's death, Rintaro chooses to pursue Suzuha with both Daru and Mayuri, preventing her from leaving for 1975. Her identity as a time traveler, John Titor and the true nature of the search for her father are revealed. Using a pin belonging to her father that she brought from the future, the group attempt to identify him, but are unsuccessful. Meanwhile, Daru attempts to fix the flooded time machine. After fixing the time machine, Suzuha prepares to leave to 1975 and obtain a IBN 5100, but Mayuri interrupts and reveals to the group that she has managed to work out that Amane's father is Daru. The two have an emotional "reunion" and Suzuha leaves in the time machine, sending Rintaro a mail containing only the word "Goodbye". However, Daru's repair was incomplete and the time machine malfunctions. Although Amane makes it to 1975, she is amnesiac and only remembers herself as "Suzu Hashida". She aids the young Yugo Tennouji and acts as his mentor, but in 1999, her memories of 2010 return and she suffers a breakdown after realizing that she failed to obtain the IBN 5100 despite meeting her father and sharing experiences with all the lab members. One year later, she writes a farewell letter to Rintaro, telling him of her tragic fate, and entrusts it to Yugo, who gives it to him in 2010. After writing the letter, Suzuha hangs herself.

Suzuha's Ending
In this world line, the events of World Line Divergence 0.337187% recur endlessly due to Rintaro being unable to decide between saving Suzuha or Mayuri, so he repeatedly uses the time leap machine to re-live the two days Suzuha spends with the lab members endlessly. However, after possibly hundreds or thousands of loops, Suzuha realizes time is looping and confronts Rintaro. After discovering the truth of her suicide, she asks him to come with her to 1975 to ensure that she will not hang herself and will secure an IBN 5100. Rintaro's emotions begin to revive after this. The two enter the time machine and travel to the past, and what happens to them is left open.

1975
After Rintaro prevents himself from stopping Amane from leaving after her failed meeting with Daru, she leaves in the unbroken time machine and her memories remain intact after the journey. She secures an IBN 5100 and mentors Yugo Tennouji under the name "Suzu Hashida" (which suggests that she figured out that Daru was her father, despite not meeting him before travelling through time). However, she dies in 2000 at the age of 43 from an illness caused by her time travelling. Her Divergence Meter passes into Yugo's possession. Unlike in World Line Divergence 0.337187%, she does not die in anguish and accomplishes her mission, passing on the IBN 5100 to Yukitaka who in turn delivered it to Yanagibayashi Shrine for Okabe in the future.

Steins;Gate 0
In the Beta Attractor Field, World War III breaks out. Daru invents the complete time machine that can travel backwards and forwards in time, which Suzuha uses to travel to 2010 to convince Rintaro to save Kurisu Makise and change the past/future. This Suzuha is aware Daru is her father. Her personality is slightly different from the Alpha world line Suzuha. When Rintaro refuses to attempt to save Kurisu again, Suzuha is angered, but is conviced by Mayuri and Daru to let Rintaro come to his own conclusion. Not able to waste more fuel for the time machine, Suzuha remains in 2010 for the next year, posing as Daru's younger sister.

In the final iteration of Beta worldlines, after the Skuld D-Mail has been received, she and Rintaro travel back to July 28, 2010 to save Kurisu. After securing Kurisu's life and faking her death to trick the past Rintaro, Suzuha disappears, as in the rebuilt future, Daru's time machine was not invented and she did not travel back to 2010.

Robotics;Notes
After the events of Steins;Gate, in Robotics;Notes it is revealed that Daru got married and has a daughter, who may be the Steins Gate world line's version of Suzuha. However, she doesn't appear during the events of Robotics;Notes.

Trivia

 * Suzuha's voice actresses, Yukari Tamura and Cherami Leigh, also voices her mother.
 * Obtaining Suzuha's ending finishes the game earlier than usual, as it takes place during chapter 6. Most of the other endings take place during chapters 7-10 of the game. It is also the only ending where Rintaro's ultimate fate is unknown.
 * Suzuha made an appearance in Steins;Gate: My Darling's Embrace as one of the main possible romantic interests of Rintaro. Initially, her existence in this attractor field is odd, since this visual novel takes place in an attractor field where SERN's influence is almost non-existent, so Suzuha would have no apparent reason to appear in 2010.
 * Suzuha's cat maiden name in My Darling's Embrace is Rinrin NyanNyan.
 * If the cosplay addon is activated in the Steins;Gate visual novel, Suzuha's new appearance resembles Motoko Kusanagi, a character in the Ghost in the Shell anime and manga series.
 * She is Lab Member 008, the last Lab Member introduced in Steins;Gate. Joined the lab during episode 10. She is recruited by Rintaro shortly after Suzuha tells him about her search for her father.
 * According to Steins;Gate 0, she left for 2010 in August 13th, 2036, thus by Steins;Gate 0's main plot, she would be 19. August 13 is also the same date that Mayuri would die in the Alpha Attractor Field in 2010.
 * The scenario writer of Steins;Gate, Naotaka Hayashi, apologized to the fans about the ambiguous ending of Suzuha's route in the Steins;Gate Visual Novel, and said that due to the efforts of Suzuha and Rintaro, their and the future of the world line is certainly happy. However, since he was not the writer for said ending, this claim is questionable.
 * Suzuha had never had a cellphone or ridden a bike before going to 2010. Though she had ridden a motorcycle before.
 * In the OVA, Rintaro encounters a girl with a face very similar to Suzuha's. The girl mentions that a psychic told her that she would have a child in 7 years, implying that she might be Yuki Amane.
