Dogma in Ergosphere is the twelfth episode of the anime adaptation of the visual novel Steins;Gate .

Tension builds at the Lab when Makise and Suzuha both show up for the party, but that's just the beginning. As the night draws to a close, armed thugs -- led by a familiar face -- come looking for the time machine.


We see Okabe in what appears to be a barren wasteland. He sees what appears to be Mayuri in the distance. She tells him that they are 70 million years in the past, and that they are going to die, though “their wills” will live on.

The time leap machine has been completed. Kurisu explains how it works, pointing out that they need a human subject to test and see it it actually works. However, Okabe declares that they will go public with the machine instead of experimenting with it on their own. Mayuri, Kurisu, and Daru agree with his decision.

Okabe and Kurisu go shopping for the Lab's upcoming “development conference.” Kurisu expresses her relief that they called off the experiment.

After an embarrassing conversation during their trip, the two make it back to the Lab. Daru is already there, and Mayuri then shows up, along with Suzuha. Sparks fly as Suzuha and Kurisu get into an argument; Okabe tries to stop them, but it's Mayuri who calms everyone down.

After some eating and games, Okabe and Mayuri talk on the roof. Mayuri notes that the Lab has lots of members now. She asks him if she needs to be his hostage anymore. Before Okabe can answer, Daru calls the two of them back down to the Lab.

They all tune in to the breaking news: bomb threats have shutdown the train in the city. Daru tells Suzuha about them hacking into SERN. This startles her, causing her to abruptly leave.

After she leaves, Okabe notices something strange: the hourglass on Daru's desk has... stopped; no sand is flowing from the top to the bottom. Mayuri then notices that her pocket watch has stopped working.

As Okabe worriedly wonders what all these things mean, 5 armed men with masks rush into the Lab, surprising everyone. With their hands above their heads, they look on as a familiar face slowly steps before them: Moeka Kiryu.

She declares that SERN is confiscating their time machine, as well as taking Okabe, Kurisu, Daru into custody. When Okabe asks about Mayuri's welfare, Moeka says she is “unnecessary.” Moeka shoots Mayuri in the head.

Okabe, now in shock, gazes at Mayuri's lifeless body on the floor. He goes to hold her, yelling her name.

He begins to cry, wondering... what is going on.
