In response to the shock of the evening’s events that have led to the destruction of the time machine, the recriminations fly between Rintarou, Daru and Maho. All of a sudden, Rintarou demands that Daru and Maho finish the Time Leap Machine so he can go back and try to undo what’s been done.
This leads Maho to admit that, at present, she doesn’t have the know-how to discover the secrets of machine by herself in time (it will only go back about 48 hours). That means having to sacrifice her desired quest to attain the same answers as Kurisu, and instead just be given the answers by Rintarou.
Considering the stakes and the tiny window of time they have to work with, it’s the only choice she could have made, though it sets aside her scientific pursuits and just getting the thing built ASAP, it cements her role as an official Lab Member, working together as a team.
While Rintarou verifys that there were no remains of Mayuri and Suzuha— suggesting they may not be dead—the time leap machine construction proceeds anyway, seeing as how there’s far too much uncertainty about the fate of the two young women to simply sit back and do nothing. (We don’t learn anything more about the nature of Mayuri’s text, or whether it was a D-mail).
Feyris and Ruka do their part keeping the machine-building team fed and refreshed as they work tirelessly for the next 48-odd hours, successfully hacking into CERN and even getting Tennouji to switch on the 42″ CRT downstairs. Rintarou observes that the lab is suddenly a lot “livelier” and more fun than it had been in a long time. It’s just too bad Mayuri isn’t there to see it.
But enough “too bads”; it’s time for action. After waking up and mistaking Maho’s sun-bathed black hair for Kurisu’s red locks, Rintarou gathers the troops, an in a speech (that unfortunately doesn’t devolve into the chuunibyou intensity of Hououin Kyouma), thanks everyone for their hard work, including Amadeus, who blushes when he calls her Kurisu.
With that, the Phone Microwave (Temporary Name) Unit-02 is activated, and Rintarou leaps two about two days before the shit hit the fan (July 7). With so little time having passed since his origin, Rintarou has little trouble convincing Daru and Maho that he is indeed from the future, and they need to get to work deleting Leskinen’s data to preempt his move against them.
Rintarou also arrives at the rooftop of the Radio building a full hour earlier than “last time”, and rather than getting shot by Suzuha, Mayuri is successful in convincing him not to stop her from carrying out Operation Arclight – going back to August 21st and convincing him not to give up on searching for the Steins Gate.
Unfortunately, Judy Reyes, Kagari, and Leskinen interfere earlier than last time. Suzu and Rintarou are able to subdue Judy (who apparently represents DURPA), but Kagari and Leskinen appear shortly thereafter. Thankfully, this time we don’t have to sit and listen to him explain his plan and laugh like a Bond villain.
Suzu and Mayuri seal themselves in the Time Machine and it begins to activate…but Leskinen calls his air support to fire a missle at the machine, and Rintarou is right back where he started. His purpose for going back—saving Mayuri, Suzuha, and Kagari—has failed, and he fears that like saving Mayuri in the Alpha World Line, there may be no way to save the time machine in the Beta.
However, there’s no reason he can’t go back to the lab, have Daru and Maho finish the machine, and leap back again—and that’s exactly what he does. s he said in his speech before his first attempt, he’s prepared to fail dozens, hundreds, thousands, even a million times, but he won’t give up as long as he has the means to continue. Maho tells him to tell all her counterparts he meets that she promises to help for as long as it takes.
However, something strange happens after his second attempt: there seems to be a longer delay before he actually leaps, and the screen that displays the date and time for us suddenly stops a July 6 and cracks. That doesn’t bode well for having a third attempt, let alone thousands more…not to mention there are only four episodes remaining.
