Accelerator manages to escape and he breaks into a nuclear facility where he is surrounded by Hound Dog units. They split into separate squads with the intent of killing Accelerator, Touma, Index and any known witness they see and retrieve Last Order.
While they're chasing after Accelerator, they break into the facility only to have all of the members get slaughtered and brutally gunned down by him and eventually a nearby hospital. Touma tries to shake them off while protecting Last Order but he gets surrounded and cornered by Hound Dog soldiers until they are killed upon Vento's arrival. Touma then tried to get Mikoto to help him while he went face-to-face with Vento and engaged her in combat. Another group of Hound Dog soldiers are with their commander but they are killed by Accelerator during the fight between him and Amata.
In the aftermath of the 0930 Incident, the surviving members from the conflict regroup and are placed under the command of Measure Heart, a former operative of the SCHOOL organization.
