Description
Rintaro Okabe, self-styled as Hououin Kyouma, adopted his eccentric "mad scientist" persona following the death of Mayuri Shiina's grandmother. He created this identity to prevent her emotional withdrawal, declaring her his hostage. The persona involved dramatic declarations, maniacal laughter, and claims of battling a shadowy "Organization," exhibiting chuunibyou behaviors. On the Steins Gate world line, this was inspired by an encounter with a time-traveling Kurisu Makise at a train station, where she kissed him. On certain beta world lines, the inspiration came from a time-traveling Kagari Shiina.
He founded the Future Gadget Laboratory above an Akihabara CRT store, naming himself Lab Member 001. Mayuri Shiina became Lab Member 002, and Itaru Hashida (Daru) joined as Lab Member 003. Their experiments accidentally produced the Phone Microwave (tentative name), a device capable of sending text messages (D-Mails or DeLorean Mails) to the past. This attracted organizations like SERN, also researching time travel.
Okabe possesses "Reading Steiner," an ability letting him retain memories across world lines after shifts. It manifested during a month-long fever in late 1999; doctors considered his recovery miraculous. He later theorized the illness activated Reading Steiner due to the Y2K problem.
His initial personality featured social ineptitude, melodrama, and hypocrisy—demanding others use his alias while assigning them unwanted nicknames. He showed poor prioritization, kept others uninformed during crises, and acted forcefully, such as assaulting Luka Urushibara to confirm biological sex. Witnessing Mayuri's repeated deaths shattered his chuunibyou facade, revealing a serious, rational, guilt-ridden individual. Numerous time leaps exacerbated this, causing clinical depression, frantic behavior, and a severe guilt complex where he blamed himself uncontrollably. In one visual novel ending (Suzuha's route), this trauma nearly erased his regard for consequences, though he reverted after confrontation.
After Kurisu Makise's death in the beta world line (*Steins;Gate 0* start), he suffered psychological collapse. He abandoned the Hououin Kyouma identity, ceased lab visits, and lived as a "normal" university student. He developed PTSD, experiencing panic attacks triggered by Kurisu reminders and requiring daily anxiety medication. Consumed by survivor's guilt and believing changing the future dishonored Kurisu's sacrifice, he refused further time travel despite knowing World War III was inevitable. His appearance shifted: neat black dress shirts, blazers, slacks, and professionally combed hair replaced his lab coat.
His *Steins;Gate 0* involvement centered on testing Amadeus, an AI housing digitized Kurisu memories. Interactions with "Amadeus Kurisu" triggered trauma but provided a fragile connection. Through these and friends' urging, he gradually regained determination. He performed over 3000 time leaps from 2036 back to 2010, demonstrating his core trait of enduring suffering to protect others. He ultimately sent a critical message to his past self instructing him to "deceive the world," instrumental in reaching the Steins Gate world line.
In the film *Load Region of Déjà Vu*, set post-main events, he suffered severe time travel side effects: visions of alternate world lines. He distrusted time travel, believing past alterations carried unintended consequences. He preferred erasure over letting Kurisu use time travel to save him. The film concluded with him temporarily vanishing before returning.
Spin-offs like *My Darling's Embrace* explored non-canon romantic routes with Kurisu, Mayuri, Luka, or Faris, often involving mundane issues like lab bills. *Robotics;Notes DaSH* depicted him working in America on "Worldline Theory," reinventing the Divergence Meter and contacting Daru about world line instability.
