Shouichi Makise

"Why did you have to be so talented!? I detest you! I hate your very existence!"

- Chapter 11

Shouichi Makise (牧瀬 章一, Makise Shōichi), publicly known as Dr Nakabachi (ドクター中鉢), was a scientist researching in the field of time travel. He is later revealed to be the father (and attempted killer) of Kurisu Makise.

Personality
Shouichi is a bitter and resentful man. He hates the greater scientific community for rejecting and mocking him and despises Kurisu for disproving his theories. By the start of the game, his hatred for Kurisu had grown so intense that he desired to use a time machine to erase her existence and attempted to kill her in a fit of rage. He cares more about being proven right then anything else. This being the case, he is okay with taking credit for the work of others if it means he gets the respect he feel like he deserves.

According to Kurisu, he was once a very considerate and kind father. As shown in Babel of the Grieved Maze, his personality used to be similar to Rintaro Okabe, with him being insistent his friend group being referred to as the "Theory of Relativity Transcendence Committee" and using the name "Pr. Nakabachi" out of delusions that his life would be in danger due to his accomplishments. However, over time, the constant rejection & mockery by the scientific community as well as his dream unintentionally being denied by his own daughter eventually warps Shouichi into the person we see in 2010.

Background
In college, he was friends with Yukitaka Akiha, with Yukitaka funding his time travel research early on. In the Alpha Attractor Field, they were both inspired by their mentor and the three of them were known as the "Theory of Relativity Transcendence Committee".

After college, Shouichi got married and had a daughter, Kurisu Makise. He and his daughter would often have discussions on physics together. Shouichi was the one who got her her prizes monogrammed spoon, promising to get her a matching fork the next year. However, things began to change after the deaths of both Yukitaka and Suzu. He began to work on his time travel research more obsessively, vowing to himself that he would use time travel to go back and save their lives. On her 11th birthday Kurisu's genius ability began to show, and she disproved a theory of his for the first time. This caused him to snap at her and leave the house. He went to the Akiha residence with the fork he intended to give her. While there, he left a recording where he laments the deaths of Suzu and Yukitaka and expresses his desire to create a time machine in order to fulfil their hopes and to save them both from their fates. He also expresses his regret at how he behaved towards Kurisu.

However, despite his initial regret, as Kurisu went on to disprove her father's theories one after another, his resentment grew. This, combined with Shouichi's field of study, time travelling, led to the man becoming a laughing stock of the scientific community and heavily strained his relationship with his daughter. He would begin taking his anger out on his wife leading to their separation. However while they separated, they never officially got divorced. By 2010, he had not spoken to Kurisu in seven years.

Wanting to show off his new theory, Shouichi invites Kurisu to his conference at Radio Kaikan in July of 2010.

Plot
The story of Steins;Gate begins with Rintaro Okabe and Mayuri Shiina attending Dr. Nakabachi's press conference about time travel. His presentation angers Okabe, who accuses him of plagiarizing John Titor's research. He loses his temper and yells at Okabe, ordering him to stop. Before the argument can escalate, Kurisu pulls Okabe out of the room. He is uninvolved with the majority of the story after this point.

Alpha Attractor Field
In the Alpha Attractor Field, Dr. Nakabachi cancels his press conference after a satellite crashes into Radio Kaikan, destroying the room he was going to speak in.

He later has a call with his daughter where he refuses to meet with her.

In Babel of the Grieved Maze, he appears on a talk show where he is mocked by the host. Following this Kurisu once again contacts him but he angrily yells at her and tells her that he wants to use a time machine to go back and erase her existence. Later on, Faris gives Kurisu a recording that Shouichi had left revealing that he did regret how he treated Kurisu at one point and why he was so upset at her disproving his thesis. This event gives Kurisu the confidence to go back to the lab and confess to Okabe before the world line changes.

Beta Attractor Field
At the very end of the plot of Steins;Gate, Okabe along with Suzuha Amane, time travel back to the day of the conference to prevent Kurisu's death. Okabe travels to the location of Kurisu's death and sees her enter the room with Dr. Nakabachi. It is revealed that his real name was Shouichi Makise and that he is Kurisu's father. Kurisu reveals to him that she wrote a thesis on the possibility of time travel and wanted to co-publish it with him in order to restore both his reputation and their relationship. Shouichi, while interested in publishing the thesis, refuses to share the credit with his daughter, despite not having actually contributed to the thesis. Kurisu attempts to reason with him, but this ends up further angering him, and he attempts to murder her. Okabe tries to stop him, but unintentionally stabs Kurisu himself. While Okabe is lamenting his action, Shouichi grabs the thesis and runs away.

Shouichi later takes the thesis and defects to Russia. The research documents were later saved from a plane fire by Mayuri's metal Upa, which triggered the metal detector. The thesis is later used as the basis for Russia's time travel research, contributing to the beginning of World War III.

In the Beta continuity shown in Steins;Gate 0, it is revealed that he is more or less kept prisoner in the country to help with research and development of a time machine, and that the published version of the paper is actually an inferior copy written by Nakabachi himself to poorly mimic the theory and is ridiculed among scientists. This aims to distract the rest of the world from the actual research, but also from the chaos ensuing from various organizations tracking down what remains of Kurisu - the paper's actual author, whose existence became apparent when Nakabachi's lack of actual knowledge shone through - in order to properly reconstruct the time machine.

Steins Gate World Line
Events play out the same as in the Beta Attractor Field until Shouichi attacks Kurisu. This time, instead of interfering directly, Okabe taunts the man into stabbing him instead. After stabbing Okabe, Shouichi takes the thesis and flees, later attempting to defect to Russia, like in the Beta Attractor Field. However, with Okabe having arranged things so that the Upa put into the envelope by Kurisu is a plastic one, the metal detector does not go off and the papers get destroyed by the cargo fire on the plane, foiling Shouichi's plan.

He then swore vengeance on the Russian airlines, whom he blamed for the destruction of the research papers and was detained by Russian authorities. He was also investigated for stabbing Okabe.
