Ichise makes his way back to Lux through the air vent helped by Sakimura who has returned to the dead world above.  He discovers that his limbs no longer work.  After he arrives underground he is told that Oonishi has done something to the obelisk to cause the power to cease.  Shinji goes back to the Hill and attempts to kill everyone in the Class.  After killing several, he is killed and then his killed turns the gun on himself.  Oonishi hears a Ran's voice as he approaches the obelisk telling him to kill her.  He stabs the obelisk with his sword as the crowd of people behind him open fire on him.  All this happens just as Ichise shows up.
