As the fight continues and all seems lost, Storm Team lead a valiant assault on the Brain, much to the surprise of HQ, who thought everyone had died. However, personnel in an undamaged part of the destroyed final EDF Command Headquarters site activate a still-surviving secret weapon, the Satellite Blaster, hitting and presumably destroying the Mothership. As the fight continues, a Mothership attempts to break into the combat area to support the Brain. The Tactics Officer advises that Storm Team attack the top of the Brain to destroy it. After the Ravagers destroy EDF Command Headquarters and a series of backup EDF Command Headquarters sites and the Brain sinks the Eighth Fleet, surviving EDF forces muster and attack the Brain in a desperate final battle, in the mission Star Eaters. Storm Team joins in with an EDF assault on the Brain, which is hovering over a massive crater, in the mission Fallen Flagship, but the Brain flees before it can be destroyed. However, unable to escape, Ohara is attacked and presumably killed by the Ravagers. In City Flaws Ohara confirms the existence of the Brain and relays it to command. In Monster Party it is stated that investigations are occuring all over the world, and Ohara personally explores several meteor impact sites that fell several days prior to the Earth Eaters' arrival in this mission and Labyrinth of Light. When the Earth Eaters arrive, he believes that there are 'far too many of them to be working on their own' and that they need a command module of some kind to oversee and direct the invasion.

Ohara first ponders over the possible existence of the Brain during the mission Machine Squad.
