A non-canon extension of the True End of the original game. Unlike the modern visual novel format of the original game, this retro game perfectly mimics the style of graphical text adventure games from the 8-bit PC era (e.g. PC-88), with the player typing short commands to interact with and explore the game world. It features all backgrounds and characters drawn in a low-color pixelated style with emulated scanlines, chiptune music played through an emulated FM chip, and no voice acting. The premise of the game features Okabe receiving a D-Mail from himself in 2025 that states that he must save the future by reclaiming an IBN 5100 from a person under of the alias "Knight-hart".

Rintarou is an eccentric individual, a self-proclaimed mad scientist and often refers to himself under the alias of Hououin Kyouma, which is also the name he uses to introduce himself to other people. Mayuri and Daru refer to him by the nickname Okarin, a portmanteau of his surname and given name. He is the founder of what he calls the "Future Gadget Laboratory" in Akihabara where he spends most of his time. Rintarou gives off the appearance of being delusional and paranoid, frequently referring to the "organization" that is after him, talking to himself on his phone, and engaging in fits of maniacal laughter. Most of the time he takes on a fairly arrogant personality. He is usually seen wearing a lab coat. <hidden by spoiler settings> The character is 18 years old and a first year student at Tokyo Denki University.

Kurisu is a neuroscience researcher at an American university, and can speak and read English well. Having had her research published in the academic journal Science at the young age of 18, Makise is extremely talented. She skipped a grade in the American school system. She does not get along with her father and has not spoken to him in many years. Okabe often just calls her assistant or one of a number of nicknames he comes up with, such as "Christina", "the Zombie", and "Celeb Sev", none of which she likes. She is considered a tsundere character; she dislikes this characterization as well, strongly objecting whenever Daru mentions it.

Ruka is a friend of Okabe. His appearance is that of a female and he acts in a feminine way due to his upbringing, wearing girl's clothing within and outside his father's temple. He is also a close friend and classmate of Mayuri's and is often asked to try on her cosplay costumes, but as he is quite shy, he generally refuses. He is unsure of his feelings towards Okabe, who calls him by his nickname, Rukako, containing the feminine suffix -ko, to denote his feminine appearance, and thinks of Ruka as his pupil.
