With the ability to utilize SERN's LHC to compress memories into D-mail size, Kurisu completes her 'time leap machine', capable of traveling up to two days into the past. However, Rintar?, still tortured by the threatening texts he has received, decides against performing an experiment, instead suggesting they announce their discoveries to the public. As the lab members decide to have a party, Kurisu comes into conflict with Suzuha, who claims she is destined to become a SERN spy, but Mayuri manages to calm things down. While a bomb threat is televised, Suzuha, after hearing about the lab's connection to SERN, suspects something is terribly wrong and leaves. Just then, the lab is attacked by a group of armed men, led by Moeka who reveals herself to be a SERN spy. Demanding Rintar?, Kurisu and Itaru hand over the time machine and come with her, she decides Mayuri isn't needed and kills her.
