The Beta-world Suzuha explains that preventing Kurisu's death can lead to a world line called Steins Gate, where neither SERN's dictatorship nor World War III occurs. Okabe travels with her to the day of the Radio Kaikan seminar. He briefly crosses paths with Kurisu, creating the confusing encounter she mentioned when they first met, then hides near the room where she will die. Kurisu confronts her father, Doctor Nakabachi, who intends to steal her time-travel paper and claim it as his own. Okabe intervenes when Nakabachi attacks her, but during the struggle he accidentally drives the knife into Kurisu himself. Nakabachi escapes with the research that will reach Russia and ignite the future arms race. Horrified by causing the death he meant to prevent, Okabe returns to the present and refuses another attempt. Mayuri slaps him and reminds him that giving up contradicts the person he has always chosen to be. Suzuha then unlocks the scrambled video message from Okabe's future self. The plan is not to erase the events that inspired his journey, but to deceive his past self: Kurisu must survive while the younger Okabe still sees her apparently dead in a pool of blood.
