Picking up one of his previously built "Future Gadgets" from the lab in order to use its liquid as a substitute for Kurisu's blood, Okabe and Suzuha return to the day of Kurisu's death. First, Okabe makes sure to obtain the metal toy he previously gave to Mayuri ahead of time in order to prevent it from reaching Kurisu and, later, Nakabachi, as it would prevent Nakabachi's paper from being destroyed due to an onboard fire. Finding that the liquid in the gadget has dried up, Okabe provokes Nakabachi into stabbing him before knocking out Kurisu with a taser. Letting Nakabachi escape with Kurisu's theory, Okabe uses his own blood from his stab wound and the unconscious Kurisu to recreate the scene his past self saw. As Okabe returns to the present, Suzuha gives her thanks before she disappears, as she does not exist yet in the Steins Gate world line. After he recovers from his wound, Okabe starts giving out badges to the lab members he recruited in other world lines, saving one for Suzuha, who will be born in seven years. While walking in the streets of Akihabara, Okabe reflects on his experiences and his time with Kurisu, and coming to terms with the fact that she may not remember their time together. Just then, Okabe encounters Kurisu, who was looking for him to thank him for saving her life. Noting that Kurisu appears to have retained memories of the alternate world lines, Okabe accepts their meeting as being the decision of the Steins Gate world line. (Source: Wikipedia)
