A student currently studying in Tokyo Denki University and also the founder of the Future Gadget Laboratory (未来ガジェット研究所 Mirai Gadget Kenkyuujo). A self-proclaimed mad scientist and often refers himself under the alias of Kyouma Hououin (鳳凰院凶真 Hououin Kyouma), the name which he also used to introduce himself. Mayuri and Daru refer to him by the nickname Okarin (オカリン), a portmanteau of his surname and given name. He is highly dellusional, arrogant, self centered, and always potray himself to be constantly under chase by his made up fictional organization; and seen talking to himself on the phone most of the time. He loves drinking Dr.Pepper, and claims it to be a drink for the intelligent people. Further more, He is always seen wearing a white lab coat, commenting that each scientists should wear a lab coat to prove that they are one.

Despite being arrogant and self centered, he can be a pushover when pressured and dare not go against anyone who is bigger than him. He is also kind and considerate, treating his lab members as friends, and is especially protective of Mayuri Shiina, who he considers her to be a sister figure. Though he is not as smart compared to Kurisu Makise or Itaru Hashida, he spends most of his time thinking up various inventions, although most of inventions ended up pointless, his eighth invention, the Phone Microwave (Name Subject to Change) is proven to be an invention that brought revolution to the science field. His dellusional mindset also gave him the habit to give names to objects, events and people. Especially nicknames, which annoy Makise Kurisu due to his constant attempt on giving her different nicknames.

During the course of the game he is the only character who experienced different, alternative timelines along with blizzare phenomenons with his creation. His repeated experiments on D-Mails can be seen as playing with fire, as he did not realize the consequences of experimenting with cause and effect, and spends half of the time fixing the timeline back to the way it was. By doing so he realize the importance of losing something dear to him, which completely rebuked his personal motto on "chaos and disorder".

.....Hello, it's me. ......what? The article contains the risk on listing too much information about me? Damn, the organization sure is adamant in putting me to shame eh? Can't help it, this in return will make me famous throughout the world, and it has to be the choice of Steins;Gate. So it will be, El Psy Congroo

Difference Between Anime and the Visual Novel

Episode 1

  • In a scene where Okarin met Kurisu again is potrayed differently : In the visual novel, he was shocked to see Kurisu alive, only to check on Daru's handphone later and found out that his message has been divided into 3 different parts, with all getting sent back one week earlier. The order is however the opposite in the anime version.

Episode 5

  • While this is not shown in the game, Okarin had a small game with Kurisu on Rainet Access Battlers, which he had lost to Kurisu.

Episode 11

  • In the VN, the scene where Okarin checking on both Mayuri and Kurisu after getting a threat message was done with a hillarious effect. While the anime version potrayed Okarin in a different way where he remained scared throughout.
