Chapter 01: -Time Travel Paranoia-

Story summary [Heavy-spoiler]

Got New CG: Rintaro looking at screen with Mayuri & Daru at background Rintaro staring at the screen, explaining about the Future Gadget Laboratory: the location (in Akihabara on the second floor of CRT shop building) and the members (Lab Mem Number 001 - Okabe Rintaro Hououin Kyouma, Lab Mem Number 002 - Shiina Mayuri, & Lab Mem Number 003 - Hasida Itaru). Then he show the Future Gadget Laboratory homepage which showcase eight gadget they've created so far. Rintaro step back, revealing he playing game named 'Alpacaman 2', where you speak to Alpacaman through mic and watch him react. Frustrated from the silent treatment from the game, Rintaro smack the TV and it got short circuited. The CRT TV won't come back to live no matter what Rintaro do, so he lie down on couch and recalling what just happen an hour ago. Rintaro panicked at suddenly empty street, devoid of people and vehicle and Mayuri who stand him didn't seem to share his confusion about the situation. Looking around for clue, Rintaro look at the Radio Kaikan top floor and saw the satellite that supposedly sitting on top of rooftop now crashed at the floor where the Doctor Nakabachi's press conference was held. Police appear and asked Rintaro & Mayuri to leave the premise. Rintaro ask the police about the mass disappearance & Kurisu was stabbed inside the Radio Kaikan but the police dismissed him for the nonsense and quickly escort them to the UPX, which packed with people because of the blockade. After that they come back to the lab and the news on internet only talking about the satellite, nothing about the mass disappearance nor Kurisu stabbing. Rintaro finally concluded everything was Organization cover up and drank Dr P soda for celebration. Rintaro open the curtain to reveal another room, the development room, and ask Daru if he knew what's wrong with the Gadget No. 8, PhoneWave (name subject to change). PhoneWave is remote-controlled microwave, calling the phone attached to the microwave to start it from afar. Daru still cannot figured out the freezing phenomenon that Mayuri accidentally found (the microwave refrozen the chicken Mayuri try to warm) and failed when trying to copy what Mayuri did, but when trying with banana it turns weird (turning to gelbanas according to Mayuri). Rintaro want to experiment again, grab bunch of Mayuri's banana and use his phone to call PhoneWave. After hearing the guidance, recorded using Mayuri voice, Rintaro deliberately mess up the input and enter '120#'.

Not long after the chapter start, the game will cue you to use your phone by dark-orange symbol at the end of text.
It was cue for pressing 'Phone Trigger' button and used as mean to branching story; use your phone for choice A and not using your phone as choice B.
But not all cue lead to branching story and I'll skip non-branching choice in this guide.

To continue, you need to call the PhoneWave listed on the contact list and then asked to input number to start the experiment.
Don't follow what Rintaro said for 10 times to get an achievement.

Story summary [Heavy-spoiler]

Leaping was successful and Rintaro wait until Kurisu finish upgrading PhoneWave. As soon as Kurisu finish, Rintaro announce he won't experiment and send Mayuri & Daru home while keeping Kurisu at lab. Kurisu was upset about Rintaro declaration thus she didn't believe he successfully leap. Rintaro used the passphrase the future Kurisu gave and she finally believe him. After explaining everything, Kurisu conclude that using time leap won't safe Mayuri. They need to find the cause to change the result and Kurisu tell that their machine had maximum range of 48 hours, meaning the farthest leap he could go was at 2 PM on 11th, 2 days before the machine was completed. Rintaro heard noises from outside and from the widow he saw Suzuha pale face then she ran away with her bike. Rintaro chase her after considering she act suspicious and probably know something. Rintaro lost sight of Suzuha at the station entrance and try to call her, Suzuha pick up and saying sorry & goodbye to Rintaro. Like last time, Rintaro cannot find her and head back to lab to leap then stopped Suzuha before she run away. Suddenly there's commotion and everyone looking up at the satellite that start lighting up.

Rintaro ask is the satellite was time machine and she is a time traveler, Suzuha confess that she's John Titor. They exit the building through another exit and Rintaro began questioning her again. Suzuha was John Titor who posting @channel & most of the post were true, and she run away because she though it was her fault neglecting her mission that SERN start making move. Rintaro pressed further and Suzuha agree to tell everything, to Kurisu too. Back to the lab, Mayuri and Daru was there to throw party for completing time leap machine. Rintaro try to make them leave again but Suzuha want to tell them too. Rintaro agree if Suzuha want it but ask her not to mention about Mayuri incoming death. Suzuha began explaining she was John Titor who posting @channel, part of Resistance who fight SERN and come to change the dystopian future controlled by SERN. Kurisu remind everyone that SERN was research institution and don't have political power, thus revealing her @channel username as 'KuriGohan and Kamehameha'. Suzuha explain SERN still a research institution in 2036 and the world was controlled by the SERN secret backer, The Committee of 300. Kurisu become the mother of time machine and Rintaro was famous terrorist. Kurisu won't believe she work with SERN and Suzuha think she was used by SERN. Rintaro bring out Rounders, Suzuha explain they were an independent technology research firm on paper but they actually do the dirty work for SERN all over the world. Kurisu ask about the many-worlds interpretation model to Suzuha, it was one of the lie she write to cover her track. The scientists in 2036 successfully modeled the structure of the universe, Attractor Fields model. The universe made up of worldlines and attractor fields, the worldlines exist side by side and converge to one point, the shared point of convergence called an attractor field. In order to change the future they must escape the attractor field in the moment they diverge, Suzuha learn the major divergence occurs in 1991, the collapse of Soviet Union; 2000, the year 2000 problem, and 2010, the creation of the first time machine. The worldlines aren't parallel worlds, just possibilities that exist simultaneously and Rintaro power to observe the difference between worldline was key to escape Attractor Fields Alpha. Kurisu asked how Suzuha know so much, she learned it from her dad's will who are one of the founder of the Resistance. From the will, Suzuha's dad think that the first email they sent through the time machine was the cause. They must find the email that got intercepted by SERN using their echelon and erase it from their IBN 5100 database. Suzuha mission was to get IBN 5100 to Rintaro and need to go back to 1975 to get one, but the problem is her time machine was broken, probably from the rain, and she don't know how to repair it. The rain happen more than 48 hours ago and Daru suggest to repair it. Rintaro make Mayuri & Daru to buy food and tell Kurisu & Suzuha that he'll leap back to 2PM on 11th and began repairing the time machine after Suzuha explain everything again. Kurisu & Suzuha agree and Rintaro leap before Mayuri return. Rintaro was successfully doing consecutive two leap for the first time. He quickly tell Suzuha about the time machine and go to see it to confirm the story. After believing Rintaro, Suzuha explain everything to everyone and everyone agree to repair the time machine. But Mayuri stopped everyone, she want to help looking for Suzuha's dad while they repair the time machine. Suzuha touched by Mayuri and told everyone that her father was in Akihabara in 2010. Barrel Titor was his codename at the Resistance and she only had the metal pin as her lead. Everyone agree to help Suzuha finding her dad and Suzuha stated if they didn't find her father by the time the repair was done, they need to give up since her mission was top priority. Everyone heading to the satellite while Kurisu stay behind to complete the time leap machine. Daru checking the satellite and notice it was built like PhoneWave, Rintaro asking if Daru could repair it for two days and he'll try his best after some convincing. It's night and Rintaro head back to the lab after find nothing about the pin. He browse the internet to find more information about the pin and when to sleep. Next morning, Kurisu woken Rintaro because Suzuha want to show something to him. She brought a divergence meter made from nixie tubes and it was made by Rintaro 11 years from now. It works like Reading Steiner and probably only Rintaro know the number change. Suzuha told Rintaro to reach 1% divergence, arrive to the Beta worldline and Mayuri will be saved. And she hand over the meter to Rintaro. Rintaro running around stores in Akihabara to find pin that matching Suzuha. He saw a accessory street vendor on his way back to the lab and the owner was foreigner. Rintaro ask about the pin to him but he didn't know and leave his contact if the owner know. Suzuha appear and giving Rintaro cola while commenting it's her first time seeing foreigner because there's no overseas travel in the future.

The future Rintaro was one of the founder of Resistance and killed by SERN at 2025. Suzuha never know about Daru but heard legend about 'wizard-class hacker'. Rintaro remember that he hasn't told Kurisu about the 42 inch CRT as the lifter and mail her.

Suzuha tell Rintaro her father name, Barrel Titor.

Chapter 05: -Dogma in Event Horizon-

Story summary [Heavy-spoiler]

Rintaro having nightmare about being stranded on the earth 70 million year ago with Mayuri. Awake now, the phone start ringing and it call from Faris
Action: Answer call from Faris Rintaro pick up the call and Faris reporting she hasn't get any information about IBN 5100 after the fantasy conversation ended.	Action: Not answer call from Faris Rintaro ignore the call and Faris called Mayuri instead. Rintaro tell Mayuri that he don't want to talk with Faris and Faris passed the information to Mayuri. After call ended Rintaro approach Mayuri and got info that Faris hasn't get any information about IBN 5100.
Rintaro frustrated that he hasn't obtain IBN 5100 yet. Daru who in the middle of combing SERN's database is surprised that they had direct line to SERN. Rintaro & Daru think SERN was the one who set the line, but thanks to direct line Daru could control the LHC in real time. Kurisu emerge from the development room and figured out how PhoneWave work. The microwave & phone electromagnetic wave was fused together during the PhoneWave construction and using the phone range, the electromagnetic waves could cover Tokyo. Inside the microwave, the phone electromagnetic wave accelerated the hydrogen atom collision near speed light, like LHC. But Kurisu still don't what act as the lifter for PhoneWave because the black hole produced by it turning into Kerr Black Holes, proved by gelification phenomenon. Rintaro thinks that they need to know more about LHC and ask Daru to explain it to him. After the explanation, Rintaro ask everyone if PhoneWave can beat SERN to achieve physical time travel. Kurisu propose two problem, setting destination and lifter. Setting destination was proved possible by D-Mail they sent so far but Kurisu warn not to accept that without verification. And Kurisu don't think they'll find the lifter since she already looking around for days. Rintaro got idea to turn human into data and compress into 36 bytes for save time travel. Daru don't think it's impossible but Kurisu think it could by using black hole to compress the data automatically for them and send memories instead of physical body. In her thesis, Kurisu told how she managed to find which nerve impulse that store memories and her university had technology to convert nerve impulse to data. Combine them and the could send memory to the past and Kurisu dubbed it time leap for differentiation. Rintaro excited the prospect of time leaping and tell everyone to start upgrading PhoneWave to time leap machine.
Kurisu Route Mayuri and Daru leave the lab while Kurisu and Rintaro still at the lab. Kurisu pondering what will happen when they use the time leap machine. Rintaro also think the same but told Kurisu to upgrade it first and think about it later. Kurisu trying to talk to Rintaro about her father and he agree to hear it in order the time leap machine got upgrade in schedule. She began to talk about her relationship with her father, from a daddy girl who want to understand his work to winning each theory argument they had and stop talking to her. Her father and her mother start fighting and stopped going home, then her mother suggest Kurisu to study abroad. Rintaro push Kurisu who hesitate to reconcile with her father and promise to accompany her facing her father. Kurisu dumbfounded at first but accept Rintaro offer to help her and they'll go after done upgrading the PhoneWave to Aomori.
Next day, Rintaro & Mayuri shopping for part Kurisu needed for upgrading the PhoneWave. Rintaro also need to pay extra attention to watch Mayuri who tend to wander around.

Story summary [Heavy-spoiler]

Rintaro & Mayuri finished shopping at heading to the station. Rintaro asked her why she's not working for this past few days, Mayuri took few days off to finish her costumes. Mayuri saw Moeka at the crowd and she had disheveled appearance. Moeka ask about the PhoneWave and Rintaro telling her they're in the middle of upgrading it to time leap machine. Moeka ask a little aggressive about what time leap machine is and Rintaro explain how it works. She's back squatting down after hearing the explanation and ask when it will be done. Rintaro giving estimate for about a week if nothing disturbed them. Moeka start laughing and leave the area, leaving Rintaro & Mayuri confused on Moeka behavior. Rintaro & Mayuri separate ways, Mayuri need to deliver the costume for her friends. Back at the lab, Rintaro caught glimpse of Kurisu browsing @channel which she try to hide. Rintaro quickly open back the minimized window and openly call her @channeler. Kurisu resort to @channel to feel Japanese when she's at America and ask him not to tell anyone about this. Rintaro don't think it's necessary since everyone in the lab are otaku and don't think Kurisu could keep it secret from anyone. It's already night and Mayuri staying behind at the lab later than usual, making Rintaro asking her about it. She need to finish sewing her costume and already got permission to stay at the lab after she mention that Kurisu will here. Kurisu who working at the PhoneWave heard the conversation and don't want to spend night in here if there's Rintaro in here. Rintaro refuse to leave the lab and think he managed to convince Kurisu then head to convenience store to buy dinner. On the way back, Rintaro browsing @channel and notice John Titor stop posting since week ago. Then he got another threat mail, quickly deleting it and hurriedly run back to the lab. Back at the lab, Rintaro notice Mayuri & Kurisu are nowhere to be found and start to panic, thinking they were kidnapped. He heard noise from the shower and think they killed like in horror movie. Rintaro quickly open the shower door and found Kurisu & Mayuri taking shower together. Rintaro relieved that they were unscathed and Kurisu angrily told him to leave hurling soap bar at him. Rintaro quickly retreat and wait until they're done showering. Two days has passed and they're still in the middle of upgrading PhoneWave and they'll use LHC to create mini black holes for the data compression. Rintaro was tasked to find the PhoneWave lifter since Kurisu found nothing inside the microwave that could act as it. Rintaro ask consult Daru about the threat email, but Daru assure him that SERN wouldn't notice his hack. Kurisu almost done upgrading the PhoneWave and need to activate it for final adjustment. Rintaro was send off to face Tennouji and appease him for the consequences turning on the PhoneWave. Rintaro head inside Braun Tube Workshop and saw Suzuha, Tennouji and Nae watching TV from the massive 42 inch CRT. Suzuha greet him and Tennouji quickly ask him to buy CRT which Rintaro decline. Looking at the shop Rintaro though there's might be something inside here that act as the lifter and start looking around while thinking the excuse what the incoming shaking on the building. Suzuha drag him away from Tennouji and reminding him again to be careful around Kurisu, telling him Kurisu connection to SERN and the credit for inventing time machine fall to her. Rintaro in disbelief but at the same time feels something off by the way Suzuha talk. The building start to shake, Tennouji was pissed off and raise Rintaro rent. Rintaro try to talk out about this but the way was closed when a CRT knock over. Tennouji trying to protect the 42-inch CRT by switching it off and the shaking stopped. Confused, Rintaro trying to switch on the TV again and the building start shaking again. He realized the 42 inch CRT was the lifter and dashing back to the lab after promise Tennouji to pay the raising rent and the broken CRT. Back to the lab, Rintaro tell everyone about the lifter. They do quick search about cathode tube, it used electron gun to accelerate electron and turned it into beam hitting the phosphor layer to make image on the screen. The electron gun clearly works as lifter and that also explain the PhoneWave only work at the time when the store was open. And by miracle, the electron gun have the right level of discharge to create Kerr Black Hole. Kurisu send Rintaro to face Tennouji again because they still need to do the final adjustment. Rintaro going outside to go to the store and saw Suzuha and Nae sitting on the bench outside, waiting for Tennouji to calm down. Nae was worried because Tennouji hit him hard and Rintaro assure her that he was okay. Rintaro asked Suzuha help to distract Tennouji for a moment and she agree to help. Heading inside the store, Suzuha start distracting Tennouji at Rintaro command, using her jacket to cover Tennouji face and Rintaro switch on the big CRT TV. The building start shaking and Rintaro going back to the lab, leaving Suzuha to face Tennouji alone. Back at the lab, Rintaro watching baseball to kill time and Mayuri ask him to help holding the costume she's working on. After altering it, Mayuri finished her costume and apparently she had race with Kurisu who will finish first. Kurisu congratulate her and she also finished with the upgrade. Everyone gather and Kurisu start explaining how the time leap machine work. The headgear attached to time leap machine used to record the nerve impulse around the temporal lobe and get converted in data. Then the data was sent to LHC at France to be compressed by their black holes and send it back to the time leap machine to be sent to the past like D-Mail. When arrived at the past through call, the data decompressed and automatically decode back nerves impulse, and goes straight to the brain through the earpiece. The memory could be send at time when you had the phone and the sender & the recipient must be the same person. Done explaining, Rintaro ask what to do next and Kurisu advice to hand it over to government and let it taken care by professional researcher. After some deliberation, Rintaro agree not to experiment and make public announcement about it. Everyone didn't touch the Time Leap Machine after and Rintaro ask Daru to order pizza while he & Kurisu snack shopping for celebration. While walking, Rintaro ask Kurisu if she upset with his decision but she's relieved Rintaro make that decision. Back to the lab, Mayuri also back from from visiting Luka and Suzuha come not long after for the party. Mayuri reporting that Luka & Faris couldn't come, Faris had RaiNet tournament & Luka was embarrassed to come. Then Mayuri ask Kurisu to come to ComiMa and trying to cosplay which Kurisu pretending not to interested about it. Suzuha pick fight with Kurisu, Mayuri ask Rintaro to stop them but failed and Mayuri managed to stop the fight. Peace back to the lab, Mayuri and Rintaro start talking about the growth of the lab while watching TV. Since there are more lab mem, Mayuri think to buy more chair to accommodate everyone and new microwave to warm her chicken. Mayuri think Rintaro isn't lonely anymore and told him she doesn't need to be his hostage anymore. Before asking what Mayuri means, emergency newsflash about bomb threat at the train station can be heard and all the line pass through Akihabara. Suzuha immediately leave after confirming the time leap machine was done, her strange behavior making Rintaro paranoid that SERN might come to eliminate them. Suddenly the lab door force opened by armed people with Moeka and she'll taking the time machine along with Rintaro, Kurisu & Daru to follow them. Everyone in disbelief and try to talk to Moeka but she won't listen then shot Mayuri as warning. In rage because of Mayuri's death, Rintaro was furious at Moeka and try to attack her. Moeka shot missed him by Suzuha intervene and she start knock everyone out in a flash then had standoff with Moeka. She tell the 42 inch TV was on, Kurisu understand first and ran to the development room followed by Rintaro. He stop Kurisu and insist to time leap to save Mayuri. Pressed with time, Kurisu start the machine and let Rintaro to leap.

While Rintaro setting up the time leap machine and recalling Suzuha explanation about Attractor Fields Theory. He want to believe that Mayuri's death was already prevented but the number at divergence meter tell him not. Rintaro done preparing the worst, he finish setting up the time leap machine, had remote control to turn on 42 inch CRT below through the hole on floor, and Future Gadget No. 4 Moad Snake (the humidifier) on hand. Rintaro worst case scenario happen, Moeka & other Rounders launching raid & this time Suzuha isn't here to save them. Rintaro activated the Moad Snake and white smoke fill the room, then grab Mayuri while running to development room. Rounders start to shoot and it hit Mayuri, she's dead once again and Rintaro keep moving forward despite his head grazed by the bullet. Kurisu and Daru was caught at the time Rintaro turn on the CRT then he leap. Rintaro try to think what should he and try to consult to Kurisu. Sitting on bench outside, Rintaro explain what happen so far to Kurisu. After hearing everything, Kurisu think Rintaro will achieve 1% divergence the instant he erase the D-Mail from SERN's IBN 5100 database and he'll get IBN 5100 automatically when back to the worldline Rintaro get it. Rintaro summaries that he need to undo all the D-Mail they've sent so far and Kurisu noted if he didn't withheld valuable information from her. Rintaro don't get the one day delay on Mayuri's death and Kurisu think it's either changing in divergence or Butterfly Effects then warn Rintaro not to die if he intend to save Mayuri. Agree with Kurisu hypothesis, Rintaro leap again to when the time machine almost completed.

Got New CG: Nakabachi at TV news The reporter interviewing Nakabachi, he seek asylum using the time travel thesis that saved from fire because metal Upa inside the envelope set off the metal detector. Mayuri recognize the metal upa was her and Suzuha apologies to let Rintaro go through Kurisu death but it was part of the plan. Rintaro ask what the plan is and Suzuha tell him to look at the video mail he already received before. The video is from the future Rintaro, he talk about the need to failed to save Kurisu in order to link the causality between them. Then explain how to reach Steins Gate, save Kurisu & destroy Nakabachi Paper, without changing the established events by deceiving himself. Video ended and Rintaro doesn't believe he still spouting chuuni nonsense into adulthood. He embraced it back and explain to Mayuri & Daru how to deceive the world, his past self must seeing Kurisu lying in pool of blood, but this time he will make sure Kurisu stay alive. Suzuha remind him about destroying Nakabachi Paper and Rintaro assure her not to worry but he need 30 minutes preparation. Rintaro making his plan while waiting for Mayuri to come back to get things from the lab. It was Future Gadget No. 6, the Cyalume Saber, it had function to make fake blood to make sword fight more realistic. Rintaro will use it as stand in for Kurisu's blood and once again they travel back in time. After arriving, Rintaro head to the capsule toy first at 7th floor to get the upa first. Rintarou quickly move after hearing Mayuri's voice approaching the capsule toy and down to the 4th floor. After checking he getting metal upa, he quickly turn around and saw Kurisu.

Kurisu appear and pick up the Upa and put it inside the envelope after cannot find its owner. After Kurisu walk upstairs, Rintaro also go upstairs and hid at the end of hallway. While waiting Rintaro shake the Cyalume Saber to activate the reaction making the fake blood. Kurisu appear and Rintaro recall his plan to use the saber once Nakabachi start pulling out his knife then stun Kurisu using stun gun he bought. Nakabachi appear and when they start talking, Rintaro peek inside the saber and surprised the fake blood already coagulate. It must be defective and Rintaro began panicking that his plan was falling apart. There's one way to reproduce the pool of blood and Rintaro gambling on it. Rintaro step out from his hiding spot when Nakabachi start strangling Kurisu. He let go of Kurisu and start provoking Nakabachi to attack him. Rintaro let himself get stabbed by Nakabachi and start threaten him using the stun gun. Kurisu try to help Rintaro and goes unconscious after Rintaro stun her while Nakabachi run away without forgetting to bring the paper with him. Looking the blood wasn't enough, Rintaro open his wound wider to get more blood and let out screams. Suzuha appear and surprised that Rintaro was pretty wounded. Got New CG: Kurisu lying on pool of blood After putting Kurisu on top of the poll of blood, Suzuha carry Rintaro back to the time machine. While travelling back to the present, Suzuha thanking Rintaro before she disappear once they arrive. Video playing: True Ending A month has passed and Rintaro finally discharge from the hospital. His wound are deep enough that it require surgery and the doctor told him he'll be dead from blood loss if he come to hospital late. Rintaro walking around Akihabara while carrying around the copy of pin that Suzuha brought from future, he had Daru make it while still hospitalized. He head to Yanabayashi Shrine to meet Luka and talk about his success debut at cosplay then give him the pin. Next, Rintaro head to the MayQueen and Faris told him she's about to open MayQueen second location. Faris also start participating on RaiNet tournament and Rintaro give her the pin. Heading back to the lab, Rintaro surprised to see Moeka and Tennouji introduced her as part-timer at his shop.

Mayuri and Daru at the lab, and they get another microwave after Daru repair the one he found. Mayuri a bit upset that Rintaro left the hospital without waiting for her and easily appeased with promise to buy her food. Rintaro give the pin to Mayuri & Daru, and Mayuri ask about the initial M, K, & A she didn't knew. Rintaro didn't tell Mayuri & Daru about Kurisu, Moeka, & Suzuha, and remember that Suzuha really did disappear when he get back. He'll hold onto the pin for Suzuha and give it later.
